things i thought of that will never be added because they are too complicated to code or just too hard for new players (i will edit this to be longer if i think of something else)
(note if i say "assuming you have _____ corruption" i am saying if you have all the corruption of that monster girl)
revenge cg: ending your turn on a dazed enemy's tile triggers a revenge cg, where you yourself fuck the monster girl
ram kiss fight: (assuming you have ram horns) a quick mini game has a chance to happen if you dash into a ram, where you and the ram lock horns and try to out kiss eachother, if you dominate the ram, the charge does double damage, if equal the dash does normal damage and if you lose your turn is skipped and the ram immediately uses heavenly chord
instinctual response: (assuming you have wolf corruption and have bust corruption) hypnotizing monster girls now gives you the option to breastfeed them dealing two damage for each stage of the bust corruption (medium: two, large: four, huge:six) (small:none but if your a wolf why would you tone down your bust?)
playful devil:(assuming you have imp corruption) if an enemy (somehow) survives your knight shift you now take their clothes and peg them with your tail
shrines and frenemies: shrines now have different effects to the foxes inhabiting them(attack boosting shrine, ghost infested shrines, shielding shrines and enhancing shrines (enhancing shrines passively gives echo), forgiving shrines (forgiving shrines save the fox form being defeated for every ghost or undestroyed statue near them) and yes it can happen to the shrines of the elite foxes too) and (assuming you have fox corruption) foxes now start off with friendly unless you attack them and you can now co-habit their shrines or take over them (depending on the shrine you take over)
a harpie's annoyance: (assuming you have harpy corruption) a monster girl destroying your egg now triggers 'harpy annoyance' for four turns in those four turns if you manage to catch the offending monster girl, you now also give them eggs just like how the harpies did to you when you destroyed one of theirs
