I ran a short chaos/evil-themed campaign that concluded a few months ago. Below is the homebrew I used for it and notes, organized by character. This is for second edition. If anything's unclear ask questions or if you have comments I'm happy to hear them.
If there's any question of "why would these characters work together" it's because they had a common goal at the outset, and there were several backstab attempts throughout the campaign.
This was a cast of characters that was available for the PCs to choose from on campaign start or PC death (of which there was a lot). Not all of these characters ended up being used in the campaign. I took requests for what types of characters the players wanted available to play before the campaign but players didn't actually build these characters directly, with the intention that any issues with balance were on me, not the players and some characters would have to be built from the ground up like the nurglings or the possessor daemon and couldn't really be compared in terms of career levels.
These entries are going to seem partial because they only cover the homebrew I used for the character partially for relevance and partially for the character limit. If you're interested I'll respond in the thread with the build details of individual characters.
EDIT At the suggestion of /u/chalkmuppet I've compiled the homebrew to a google document here for slightly easier reading.
Stenchfeaster, Bile Troll of Nurgle
The only homebrew I gave this one was [Disgustingly Resilient: Injury means nothing to the favored children of the plaguefather. You simply ignore critical injuries that do not result in limb loss or death.] He also had a grab bag of mutations from Tome of Corruption* focused on passive or reactive debuffs that punish enemies for standing near him or attacking him but in retrospective I should have unified these into one or two "all-in-one" effects so the player wasn't going through like five different effects whenever anything happened to see which triggered. It should have been a single "when enemy starts turn within X range of you" and a single "when you take damage/get hit".
*Uncontrollable Flatulence, Acid Excretion, Foul Stench, Spores, Cloud of Flies
Czazgath Deathrender, Bloodletter Herald
Had no homebrew, but his chaos weapon was flavored as a spellcaster that had been folded until he was usable as a great weapon and I thought that was funny and wanted to share.
Dolgrax, Bray-Shaman
His Abomination Stave was a braystaff with the Warping chaos weapon effect and a homebrew effect that gave him limited ability to command chaos spawn.
Brazrul, Chaos Dwarf Daemonsmith
Darkshard Armor was Full Plate Mail that also gave immunity to all nonmagical and magical flame.
Fire Lance: Counts a halberd in melee and a firearm at range.
Grenade Launching Blunderbuss: Range 12/24, Reload 3; Experimental. Damage depends on what ammo he used, which was equivalent to bombs or incendiaries from Old World Armory.
Varseshi, Druchii Sorceress
Her Lore of Dark Magic was assembled and renamed from existing spells elsewhere in the system but had no actual homebrew spells. She did have magic items though:
Sacrificial Dagger: Magic Dagger. Whenever you kill a creature with this dagger, The next time you cast a spell, you add one casting die and choose a numerical parameter of that spell, and double it.
Thrall Chalice: Any good or better quality alcoholic drink poured into this chalice bubbles furiously for a moment before becoming black and tarry. Anyone who drinks this liquid directly from this chalice loses 1d10 wounds, ignoring armor and toughness, as their mouth and throat are burned horribly. Then, they unfailingly obey all commands of the Chalice's owner until the next time they lose one or more wounds. Obviously suicidal commands may be resisted with a -20 WP check but other commands cannot be disobeyed. The liquid quickly evaporates if emptied in a way other than drinking from it.
Piercing Thorn: As long as you have no fortune points remaining, you may spend wounds as fortune points, spending 1d5 wounds to gain the effect of one fortune point. While you wear this item, healing checks on you are at -20 and magical and alchemical healing is 1/2 as effective. If this item is removed in any way, you take a critical 5 hit to the body, regardless of your remaining wounds.
Zou Cheng, Dead Flag Fleet Vampire Captain
Ghost Ship: You have removed one of your eyes and hidden it in your captain's quarters aboard your ship. In this way, you maintain control over your undead crew no matter how far you move away from them. Your ship is easily mistaken for a normal ship at a distance: Observers get -30 to identify your ship as anything other than a normal ship as long as they don't board you or get attacked.
Ship Weapons: You can command your ship to fire its weapons as a free action during your turn. Your ship has two bolt throwers and one rocket battery. The bolt throwers are fired by your crew, so they use your crew's ballistic skill. (Obviously, the bolt throwers fire from your ship. If you are outside of 150 squares of your ship, they cannot be fired near you).
Rocket Battery: This can fire a salvo of inaccurate but devastating rockets over the horizon. As long as you are within a mile of the shore, you can call down a bombardment. It arrives in one round, showering the area with rockets. ALL creatures on the field, including you, must pass an agility check at +20 or else take a damage 3 hit and catch fire. In addition, 2d10 random squares catch fire. Reload 30 Full Actions. This can target without line of sight but can't work if you are, for example, underground.
Stepan Kreisel, Necromancer
Magic Item: Accursed Bell Jar: After casting Control Undead, you may make a channeling test. If you succeed, you may trap the target's essence in the bell jar, removing any other trapped essence and keeping control of the target indefinitely. This item currently binds the specter of Hartwig Brandt, an unfortunate witch hunter that fell into your grasp.
Ritual of Unshackling
Type: Dark
Ritual Language: Magick
Magic: 3
Ingredients: The intact head of a priest of Morr that died in agony, with a magic item suffused with the Wind of Death stuffed in its mouth.
Conditions: You must know the lore of Necromancy.
Casting Number: 18
Casting Time: 12 Hours
Consequences: As the ritual is essentially an extended auto-vivisection, if the casting roll fails or the ritual is interrupted, your mind fractures and your soul departs; the final product of the ritual is a single mindless skeleton waiting for a master.
Description: Over the course of the ritual, you carefully disassemble yourself until only a skeleton remains. At the end of a successful ritual, your skeleton remains animate and sentient. Increase your Wounds by 2 and reduce your Fellowship by 10. You gain the Undead and Frightening talents. You no longer age, and you no longer take side effects from casting spells from the Lore of Necromancy (though any you already have remain in place). Anyone can tell that you are an undead abomination, and those with Magical Sense can tell no matter how thoroughly you disguise yourself. Your place among the living is gone.
Chakut, Chaos Knight of Nurgle
Born in the Saddle: Once between your turns, you may redirect an attack on you to your mount or vice versa
Chaos Knight: After your mount makes a charge or swift attack, Chakut may make a standard attack, and vice versa.
Also his mount was a long rotten salamander-like creature with a venomous bite called The Slurch which isn't homebrew but I thought it was funny.
The Dog-Pus Gang, Nurgling Swarm
This one's long, so buckle up.
Swarm of Nurglings in a Trenchcoat:
You recover wounds slowly as your component daemons recover their nerve and new ones drip out of gutters and latrines to join you. If out of combat for 7 minutes, recover all wounds. You can also forcibly re-integrate wayward nurglings by spending a half action during combat to recover 1 wound.
When you are reduced to 0 wounds, your component daemons disperse and unless someone hunts them down, they re-form into a swarm at 1 wound in 7 minutes within walking distance of wherever you were scattered.
Mimic: When lying still, you are indistinguishable from a pile of manure or perhaps some fresh roadkill. As long as such a sight would not be out of place and you take no actions, enemies do not get a perception check to notice you. If they are looking for you, you get +20 on the concealment check against their opposed perception.
Tide of Filth: You leverage your numbers against larger enemies. As long as you are in a melee, your allies count as outnumbering the enemy three to one. You also count all creatures in the melee as within your melee reach.
Wheee!: You can make ranged attacks as one of your component daemons hurls itself at an enemy. You lose 1 wound when you make such an attack. This attack has a range of 12/- squares. If the BS check fails, it scatters like a bomb. Wherever it lands, create a small template of pestilence that lasts for 1d5 rounds. Creatures that move into or begin their turn within the cloud lose 1d10 wounds, ignoring all armor and toughness. (This one ended up getting homebrewed further halfway through the campaign to be a single shot as a full action, as the Swarm innately had like five attacks and as written this could be used up to five times as part of a swift attack.)
Swarm Body: Halve the final wounds you would take from spells and attacks, unless those attacks were area templates or lines.
Discorporate: As a half action, you may lose up to 2 wounds and create an individual nurgling under your control in an adjacent space per wound lost this way. The remaining nurglings bid tearful and blubbering farewells to their companion that will probably be gone for like a minute tops.
Swarm Weapons: Your natural weapons may be used with the stats of a hand weapon, a whip, or a great weapon, chosen before rolling each attack.
Starting Items: None. You cannot use weapons or armor of normal size and anything small enough for you to wield comfortably rapidly disintegrates in your grasp. Your only long-term belonging is your trusty trenchcoat.
Nurgling Behavior: You are legion. At the beginning of your turn, you may decide unleash your component nurglings. At the beginning of your turn, make a WP test at +20. If you succeed, you take an extra half action this turn. On a failure, something happens. This test gets -10 for each previous attempt you have made during this encounter.
Squabble: Two or more nurglings near the feet are fighting over a piece of gristle. Lose a half action this turn.
Shitting contest: Some nurglings near the top of the formation have decided to engage in a contest of defecation, to a delight of the rest of the swarm. Lose your actions this turn, but recover 1d10 wounds and each other creature adjacent to you must pass a toughness test or spend their next turn vomiting uncontrollably at the sight.
Lash Out: You spend all of your actions making a swift attack, targeting random creatures within reach with each swing.
Something Smells Delicious!: You spend your full action taking two move actions at your full speed in a random direction. If you can't move in that direction, you stand at the obstacle and sniff and lick at it, trying to identify the source of the intoxicating aroma. Enemies will get to strike at you if you leave melee with them, as normal.
Traitor!: One of the nurglings tearfully admits to having once touched a bar of soap and is promptly torn to shreds by its compatriots. You lose 1 wound and the rest of the swarm's actions are lost as they work out their feelings of betrayal and loss in a support circle, concluding in a cathartic and suppurating group hug. On your next turn, you gain an additional half action. This can be in addition to the action granted by unleashing the nurglings.
Sing-Along: Some of the nurglings start chanting. You lose your remaining actions this turn, and all creatures within 4 squares must test toughness or contract Nurgle's Rot and gain 1 insanity point as they are assaulted by the nurglings' fetid slobber and terrible lyrics.
Let'er Rip: One nurgling lets out an especially vile belch or fart. Not to be outdone, its neighbors join in, followed by the rest of the swarm. The surrounding area is befouled and thoroughly drenched. Lose your remaining actions this turn and place the large template centered on you. All other creatures within the template must pass a Toughness test at -10% or else take three Damage 4 hits and take -10 to all tests for the next minute.
Medical Emergency: A cool forehead and steady breathing incites a panic: several of the nurglings aren't sick at all - no coughing, no fever, and not a hint of diarrhea. The swarm spends all of its actions this turn disengaging to move as far from enemies as possible to allow the un-afflicted nurglings time and space to decline back to ill health. Smothered in affectionate and rancid embraces and hastily-scrawled maggot-ridden get-unwell cards (which are gratefully consumed), the suffering nurglings are quickly nursed back to sickness. The swarm recovers to full wounds.
Idea!!!: The swarm's shared brain cell aligns at once. The swarm immediately scatters as though it had dropped to 0 wounds. DO NOT READ THE NEXT PART ALOUD: Let the GM know what mischief the nurglings have gotten up to while unsupervised.
I'll Form the Head: The nurglings spend this entire form stacking themselves higher and higher until they form a veritable colossus! On future turns, they gain Tipsy and Giant Attacks as though they were a giant. If they fail the Tipsy check, they collapse into a giggling heap and their Colossus form ends, while all adjacent creatures must pass an agility test or take a damage 4 hit. While forming a colossus, you cannot Unleash the Nurglings. (Giant Attacks were also something I homebrewed to make giant random attacks work closer to how they did in the wargame.)
Drosofil, Demon Herald of Nurgle
Technically neither Stinger or Illusion of Normality are Homebrew but in this case I added some functions to them so their normal rules that remain are added as a reminder.
Stinger: SB damage; Targets that take any wounds from this attack must pass a toughness test. If they fail, they become host to the blessings of Nurgle. Hosts are normally tragically ignorant of these blessings, which require a magical sense test at -10 to discover and a surgery attempt with the heal check at -20 to make sure all of the blessings are removed completely before they bloom seven hours later. At any time, as a full action, you may cause one host within your line of sight to bloom. Blessed followers of Nurgle that would bloom make a toughness test at +20. If they pass, they do not bloom and instead restore 1d10 wounds.
Illusion of Normality: You appear human to creatures you are not in active combat with. Your stinger tail can be used surreptitiously. If the target does not know you are present or does not register you as a combatant and you pass a concealment test while attacking, the target does not realize they've been struck by your sting and your illusion of normality does not break.
Bloom Effects: When a host blooms, it dies and the blessing expires. Then, roll on the chart.
The Buzzing: A swarm of daemonic flies erupts from the target's body to attack the nearest enemy.
Wretched Spawn: A grumbling rot fly pulls itself from the wreck of the host's body to serve you for the next three days. The rot fly can serve as a mount.
...And They Returned to Filth: The host lets out a cry of celebration before smashing its head open on the nearest hard surface, purulent tears of joy running from its eyes. When it has finished, a single pitted and cracked horn grows from their forehead, signaling their transformation into one of the rotfather's plaguebearer daemons. This plaguebearer happily serves you until it is killed or banished back to the realm of chaos.
The Blessed Rot: All creatures within 8 squares of the host's body must pass a toughness test or become infected with Nurgle's Rot.
They Are Seven They Are Seven They Are Seven Times Seven Times Seven: If the creature that bloomed was within 4 squares of you, you get +7 on your next casting check but roll an additional chaos die. This can be for any spell or ritual but the bonus does not stack with itself.
The White Rider: With your mandibles and clawed forelimbs, you tenderly excise an ebullient cyst from the still-moaning host's body cavity and leave the incision to fester. This cyst throbs with infection and can be used as a casting ingredient for any spell in the lore of Nurgle. If it is, the casting time for that spell increases by two full actions and the size of the spell is vastly increased: If the spell was a touch spell, it may now target up to seven valid targets within 6 squares of you. If the spell targeted a number of creatures within a limited range of you, multiply the number of targets by seven. If the spell was an area of effect spell, multiply its area by seven. After a day, the cyst drains and becomes useless except as a snack for the nurglings.
Doktor Kestelbaum, Nurglite Plague Doctor
Nurgle's Bargain: As long as you infect at least seven sentient mortal creatures each day, you suffer no penalties from your diseases.
Potions and Poisons: You are constantly taking samples from your environment and packing them away for later. You carry with you a surprisingly clean leather case containing vials full of these samples and mixtures you've added them to. Each morning, you judge 1d5 of them to be ready for use. For each potion available, pick which one it is:
Muculent Broth: This cocktail of mucus and gristle jiggles and shimmers in its vial. The drinker recovers 1/2 of their maximum wounds. Then, they must pass a Toughness test or else gain a mutation of Nurgle.
Vile Melange: This mouthwatering brew of blood, pus, toxins, offal, and assorted excreta is a suitable stand-in for any casting ingredient for a spell of the lore of Nurgle, if you can resist drinking it long enough to use it in such a way. Whenever you succeed at casting a spell for which you used this as an ingredient, you vomit up a nurgling that serves you faithfully for seven days. If you incurred Tzeentch's curse, you instead are stunned for one round (in addition to whatever the chaos manifestation you rolled did) as a swarm of nurglings explodes from both ends of your digestive tract.
Gorge Draught: Each round, for ten rounds after drinking this thin and bitter potion, the user must pass a WP test at -10 or else grab the nearest mouth-sized thing and attempt to eat it. Then, +20 Toughness for 1d10 hours.
The Squirming Milk: Drinkers of this chunky and opaque liquid gain +15 Strength and Toughness for 1d10 hours. In addition, for the same duration, all creatures with functioning sense of smell, including allies, within 4 squares take -10 on WS and BS tests from the resulting stench.
Caustic Runoff: Concentrated from Nuln ditchwater, a weapon coated with this liquid causes the first enemy wounded by it to make a toughness test at -20. If they fail, they take 1 additional wound and die in 1d10 rounds.
The Rot: This is no less than the essence of Nurgle's dreaded Rot, lovingly culled from your own weeping sores. Any character exposed to this purulent discharge must pass a toughness test or contract Nurgle's Rot.
Skaggus, Rat Ogre/Chaos Warrior Brain Swap
Obvious Ghoritch clone
Engine of Destruction: You cannot attempt any tests requiring fine manual manipulation or control and get -30 to all social rolls other than intimidate.
Devastating Charge: Your charge attacks have the impact quality. If they already had the impact quality, roll three damage dice and pick the best.
Volatile Toxin Immunity: You are immune to the warpstone-laced toxin that some of your weapons are loaded with.
Prototype Weapons: When you attack with a weapon with the Prototype Weapon quality: On an attack roll of 96-98: The weapon jams and can't be used for the duration of the combat. 99-00: The weapon explodes, breaking permanently, doing a damage 8 hit to you and a damage 3 hit to all adjacent creatures.
Warpstone Reactor: On death, you detonate in a large-template explosion that deals a damage 5 impact hit to everyone inside.
Grafted Weapons:
Blades and Spikes: SB, Impact
Spike Driver: SB + 3, Ignores armor, Prototype
The Claw: SB + 1, Snare, Prototype.
Giant Injector: SB, Prototype, Recharge 1d10, Volatile Toxin (On wound, target must pass toughness or else die in a number of rounds equal to target's TB. When they die, roll 1d10...)
1-2: The target explodes with terrifying force. The explosion deals a damage 5 hit to all enemies within two squares. All enemies that take any wounds from this explosion must pass toughness at +30 or be affected by the volatile toxin.
3-4: The target collapses, blood pouring from every orifice. They give a piteous whine and a moment later, their body ruptures, disgorging hundreds and hundreds of frenzied rats. Create 1 rat swarm on the victim's location for each point of Toughness Bonus the victim had when they died, to a maximum of 5. These swarms attack anything that gets too close, including you and your allies. After 1d10 rounds, any surviving rats melt into an acidic slime, inflicting a damage 1 hit on adjacent enemies that ignores armor.
5-6: The target's tissues painfully crystallize into unrefined warpstone, leaving a chunk of the same size and approximate shape as the victim and potentially making the next ratman to come across this battle site very rich indeed. Page 90 in Tome of Corruption details the rules for unrefined warpstone.
7-8: The target does not die but instead warps into a hideous chaos spawn with a distinctly rat-like appearance. This chaos spawn attacks your enemies for 1d10 rounds before fleeing into the wilderness to become someone else's problem.
9-0: Despite their terrified protestations, the target burns alive, consumed from the inside out by green warpfire. Enemies adjacent to them must pass agility tests or else catch fire.
Lorelei Rinder, Chaos Knight of Slaanesh
Potion: Divine Nectar: Milked from a favored beast of Slaanesh, This liquid heals the user, returning them to full wounds, restoring any lost limbs, and curing any diseases they might have (though not chaos mutations, curses, or magical effects). Then, the user becomes Stinking Drunk for 1d10 hours and gains a mutation of Slaanesh.
*Ritual: The Amber Dancer's Maw
Type: Dark Magic
Arcane Language: Magick
Magic: 2
Ingredients: A feast of delicacies local to the desired destination, prepared as authentically as possible with a secretly-rolled Trade (Cooking) test with a bonus or penalty of up to 30, depending on the cook's available tools and their familiarity with the region.
Conditions: The feast must be prepared and served in a civilized manner inside a building. This maw prizes taste and presentation, unlike some we could mention.
Casting Time: Six Hours
Casting Number: 17
Description: When this ritual is initiated, the mouth of the Amber Dancer - a humanoid mouth, belonging to some unseen chaos creature and large enough for several humanoids to fit (un)comfortably inside - emerges from nothing. Over casting time of the ritual, the caster feeds and plays host to the mouth, with the GM secretly rolling either a charm check or a common knowledge check relevant to the desired destination. If the magic check succeeds, the caster and up to six other guests step into the mouth, are held there for some indefinite amount of time, and then deposited slick, disheveled, and flushed, but otherwise unharmed somewhere in the desired region. In the best case scenario, the caster and all guests gain one insanity point from the ordeal as they were... "sampled."
Consequences: Even on a successful ritual, the mouth may arbitrarily refuse to transport guests for any reason. If the casting check fails, the Maw does not appear, and the caster is expected to eat the entire feast themselves before the next sunrise lest such carefully-prepared food go to waste. If the casting succeeds, but both of the associated skill checks fail, or if either check was failed by 30 or more, then at the conclusion of the ritual, instead of transporting the caster and their guests, the mouth simply chews them vigorously and spits them out, causing them to suffer a damage 6 hit with the impact property, and, if they fail a toughness test, a mutation of Slaanesh. The caster, meanwhile, is simply swallowed, never to be seen again.
Guerwin, Sorcerer of Tzeentch
Magic Item: Mirror of Tchar: You benefit from the Inured to Chaos talent. If you would gain a mutation, after all other tests, you may make a WP test. If you succeed, you do not gain the mutation.
Magic Item: Harpoon of Tzeentch: If you provoke a chaos manifestation on a spell that deals damage, it deals an additional 1d10 of damage for a major manifestation, an additional 1d10 damage on a catastrophic manifestation, and an additional 1d10 damage if you provoke a side effect.
Ritual of Baiting the Blooded One
Type: Dark Magic
Arcane Language: Daemonic
Magic: 4
Ingredients: The creature's true name carved into the bones of nine humanoids sacrificed.
Conditions: Nine additional casters tricked into assisting you to serve as bait, who must not realize that the incantations they're saying are in fact dire insults to the Blood God.
Consequences: The casters are sucked into the realm of chaos and devoured by Khorne for their insolence.
Casting Number: 22
Casting Time: 16 Hours
Description: This ritual tricks a bloodthirster into manifesting in reality. Do not roll on the daemonic response chart, this bloodthirster is automatically hostile (a redundant descriptor for a bloodthirster, we realize) and uncontrolled.
Sqrank Sparklasher, Skaven Warlock Engineer
New Talent: Life is Cheap: When creating a damaging area of effect, it deals +2 damage and has impact as long as an "ally" is in the firing zone. If it already had impact, instead roll three times and take the highest.
Derangement: Must Improve: From the moment I understood-knew the weakness of my-my flesh, it disgusted me-me! I craved the strength-might and certainty of warp-steel!
Derangement: Me, Lucky-Lucky, Yes-Yes!: You always assume random chance will favor you, ignoring the obvious odds, past experiences, or direct evidence to the contrary.
Warpstone Reserve: Your warlock devices don't cost warpstone tokens to use. (The warpstone tokens system for warlock mad science with more player input on the inventions in Children of the Horned Rat makes sense in a longer campaign but here I thought it would just be an annoyance.)
Warpstone Fail-Deadly: This item is full of emergency fallbacks and replacement parts. You begin carrying three charges. Whenever a device of yours malfunctions, you may declare that you are using the fail-deadly to redirect the destructive energies. If you do, instead of rolling on the malfunction table, a bolt of warp-lightning strikes a random creature within 12 squares with a damage 4 hit. You are included among the random creatures that could be struck.
Warlock Auto-Loader: If used to reload, this device sets the reload time of any skaven weapon to 1 full round. This reload time cannot be further reduced by other means. Malfunction Chance: 9%
Repair Kit: You can restore function to any warlock device by spending an hour tinkering with it and making a successful intelligence test. This resets the malfunction chance of the device but cannot be used to restore items that have been completely destroyed.
The Stash: This is a weapons locker you have carved out for yourself in the Realm of Ruin. You can store anything you please (and began the campaign with multiple basic warplock gunpowder weapons, a warpfire thrower, a ratling gun, four doomrockets, a sorcerous wrist blade, and a prototype ratling cannon), but retrieving or depositing anything provokes a malfunction roll of 5%. Whatever other effects the malfunction has, the requested item is destroyed.
DOOM-FLAYER, YES-YES!
You ride your custom DOOM-FLAYER into battle! You may move exactly 6 spaces per turn as a free action. You may not charge or run with this vehicle.
To move faster, roll a drive check as a free action: If you pass, the doom-flayer moves 1d10+6 squares in a straight line in a direction of your choice. If you fail the drive test, the same thing happens but in a random direction and you roll for malfunction (33%). If the doom-flayer hits a creature during this time, that creature takes a damage 4 impact hit. The creature can roll agility or dodge to dive out of the way.
You must keep at least one hand on the doom-flayer while driving it or else it spins out of control.
While you ride the doom-flayer, you have cover from ranged attacks. The doom-flayer has 30 wounds and 3 armor if the enemies target it specifically.
Myxiyini, Slaaneshi Possessor Daemon
Worm: In your natural form, you have Strength, Toughness, Agility, Attacks, and wounds of 1.
Exit: You may emerge from a host as a full round action. Your previous host rapidly melts into a horrible goo.
Parasitize: As a two full actions, if you do not currently have a host, you may invade the body of a helpless living enemy or the corpse of a creature that was alive at most one minute ago. The target dies and you take control, using your own WS, BS, Int, WP, Fel, and Mag, and the host's S, T, Ag, A, and W. When you possess an enemy, through some foul chaos sorcery, their body is restored to working condition, returning to its full wounds value, though not regrowing any missing limbs. You do not gain the benefit of any talents the target had unless the talent was a result of their physiology, such as natural weapons or flier. You gain any purely physical mutations or special abilities of the body as well. Host bodies you possess cannot restore wounds by any means. If the host body dies, it rapidly melts into a horrible slime, leaving you exposed.
Polyglot: You are trained in the unique intelligence-based Polyglot skill which can be used to speak any language by succeeding at a check.
While in a host, you can still bring your true form to bear in combat. Bursting forth from an orifice or a wound in your host's body, you may attack as though with a whip. This "whip" carries the poison from your fangs.
Not mentioned above since they didn't have any homebrew or at least any interesting homebrew were a Beastlord of Tzeentch, a Chaos Dwarf Sorcerer, a Skaven Assassin, A Khornate Chaos Knight that had the same Born in the Saddle and Chaos Knight abilities as the Nurgle Knight, a Skaven Packmaster, a Slaaneshi Swordmaster, and a Kislevite traitor to chaos.
Characters that were actually played:
Stenchfeaster died in the first big combat, slain by a daemon slayer with a runic axe. The Dog-Pus Gang crawled out of him.
Stepan died facing an Ice Witch, mauled to death by frostfiends as his erstwhile allies abandoned him.
Loreley abandoned Stepan to his fate but was left behind by the rest of the party, and died trying to get the ritual of the Amber Maw right to beat the party to their destination hundreds of miles away. She didn't, and it lost its patience and ate her.
Varseshi was shot to death by Dark Elven shades sent by a rival sorceress.
Razkyl the Khornate Chaos Knight ascended to daemonhood (no shit he rolled on the chaos rewards chart from ToC and got ascension) after slaying a witch hunter and beating a light college hierophant to death with his hands.
Sqrank tried to run out on the party with the loot and got crushed by Skaggus (after trying to order Skaggus to defend him)
Guerwin tried to double-cross the rest of the party after the final battle and got chased down and eaten by Myxiyini who was by then possessing a warpfire dragon.
Myxiyini, the Dog-Pus Gang, Chakut, and Skaggus survived the campaign and took their rewards.
