I have a small idea.
What if, at a very advanced point in the game, all enemies (zombies, skeletons, slimes, haunted knights, etc.)
develop "magical mutations" due to the potions, and the enemies practically have the same effects: huge tits, huge asses, thick bellies, thighs, etc.?
But! There's another potion that will be "invisibility."
But the effect it would have would be to make all the clothing and weapons of the victim who took the potion vanish, ensuring the enemies with "magical mutations" victory.
