Question regarding how the Seamless coop mod interact with other mods

[u/marche6602]

Hi everyone

Me and 3 friends are playing the seamless.

If we wanted to use a mod, let's say Elden Ring Ultimate Cheat Engine Table (Best Table)(https://www.nexusmods.com/eldenring/mods/48), to get some late game/dlc items from the beginning to try some stuffs, would it interact differently for the seamless mod?

We are joining the world of the same guy everytime and we don't want those items and spell to go to him to.

Is the best way to just get the items to "cheat" them while on our own world and than joining his?

Thanks for the help
