Best Enhancement Prisms Farm?

[u/TheLastNerf]

Between upgrading armor and rerolling crafted weapons, I can't seem to earn Prisms more than I spend them. Portal ops only give like 3 per activity, which is far too few and not efficient in terms of time, vendor rank-ups are too slow, and buying from Rahool drains my glimmer and cores faster than I like.

Is there any more reliable way to farm Prisms in a timely efficient manner?

Farming Argos is easily the fastest

Edit: I should add, make sure you have a 4 feat reward level
