Potion of Jincrimination

Wondrous item (potion), rare (requires attunement)

Upon attuning to this item you can bind one of your sins, mistakes, regrets, etc. inside it. Until it is drunk you are unburned by what you've done, as you forget what you've done and how terribly it turned out. 

Upon being drunk, the memories, trauma, regret, and stain upon the soul that the original sin is doubled and settles into the soul of whoever drank the potion.
