Reborn tabaxi artificer armorer with a mechanically different though RP similar “living armor”. The living armor is the reason i was “reborn” as its keeping me alive longer but the curse of the living armor is of divine nature as i stole it from an evil cult, so removing it required a monumental effort (high level NPCs basically didnt exist).

The character reached an actual satisfying conclusion as there was an “enlightenment” challenge we managed to find that was heavily skill based and artificers are obscenely good at skill challenges (dm also liked tool checks where relevant, and was lenient with the skill training rules, reborn helped too, resulted in being able to roll d20+stat+prof*expertise+int+guidance(d4)+reborn(d6) on checks i needed to push). The enlightenment ultimately lead to access to enough divine power to break both the curse of the armor and of my undeath.

Ultimately though, despite how fun the RP around it was, it was one of my more OP characters considering how much it trivialized skill checks which that DM really loved.

I tried and failed to tone it down with my next character, which thanks to party dynamic became the single most OP BS i ever made even if it wasnt crazy good alone. Wanted to make a magic infiltrator and went with changeling + aberrant mind sorcerer. Ended up getting a shadowfell shard too. Mindsliver leading to a subtle quickened shadowfell shard boosted CC spell (fav was psychic lance since it wasnt concentration and almost nothing is immune to incapacitated, though hold person, and hypnotic pattern, and the like were also thrown frequently too) was an obscenely powerful combo, and since another new player made a DPS rogue+gloomstalker build, the only way for anything to have any chance of living is lots of legendary resistance and an obscene health pool. This was also a crazy fun build, that the power of it ended up being its downfall as everything we fought ended up being several CR higher than anyone of our level had any right to tangle with. (also yes, i know you can’t normally subtle + quicken, read the Psionic Sorcery power of aberrant sorcerers)
