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)

Haven't gotten to play either of these yet, but I might someday.

1. Aberrant Mind sorcerer, race tbd. Basically, was an eldritch abomination who got bored, and turned itself into a mortal for a change of pace. We're talking "Had 30 Int and Wis" levels of abomination. So now it's stuck in a limited mortal form with all this knowledge, and no ability to use it. Can't even pronounce its own name anymore.

2. Incubus/succubus (reflavored tiefling) paladin of redemption. Nommed on the wrong soul and got purified, and now trying to atone for their past misdeeds. They're virtually starving themselves, which is why they're using a tiefling statblock instead of the normal one, only having the ability to switch sex, and the draining kiss that they never use save to keep themselves alive with a consenting travelling partner.

Silver Dragonborn Ancients Barbarian - I wanted to try a tanky build again, after not liking my attempt with paladin. He was Con primary, Str secondary, using a Warhammer and shield, and I was excited to see how the path of the ancients intersected with things like shield Master or sentinel. He was from a tribe of remnant Dragonborn after Abeir split back off. His tribe used to rely on shamans that communicated with their ancestors, but the last one had passed in his grandfather before he was identified as a new shaman. His sister died in a horrible accident, and his communication with her spirit was how he was identified. No one in the tribe knew how to help with his gift, so he went out into the world, accompanied by the spirit of his sister, to see what he could learn. His rage manifested as an icy white cloud rolling over him and falling to the ground, slowly revealing the spirits that accompanied him. I planned for him to notice and get to know more and more of his ancestors' spirits as he got more powerful - including his grandfather, a taciturn half-dragon, and a happy-go-lucky silver dragon. Unfortunately, I had to bow out of the campaign just as we hit level 3, so I never got to experience any of it. ☹️

It's been so long, either a Mega Juicer or Titan Juicer from RIFTS. https://rifts.fandom.com/wiki/Juicer . Essentially a steroid user but with super science. Massive person. Think Strong Guy from X Factor https://en.wikipedia.org/wiki/Strong_Guy . He loved western wear, but often got into situations where mega damage would destroy his outfit, so he had cargo crates full of the same black cowboy hat and duster. He became a juicer to save his sibling, they were both poor kids and sibling needed medical help, so he answered an ad for experiment subjects.
