Has a good base for the game in general. Obviously the Corruption System needs more work, far too much RNG grinding in order to get the passives for each body part.
My recommendation for the corruption system would be to have actions like "Showoff Butt I" or "Showoff Abs III" that will have the enemy you're targeting focus on that body part (To varying effectiveness (% chance) based on the action's Tier (I, II, III, IV, etc)). You would unlock the tiers along with specific passives (So no "Showoff ___" on a fresh save) so that it's easier to reach corruption levels that you've already hit previously. This way you aren't getting fucked over by RNG while also waiting 15-20 turns for a random body part to finally hit 20 corruption.
