Hey,
The thing you just described would fit more as a "bleed" effect. Also you have to remember, that it will change for the player poison cards as well.
Yeah the gold stealing will probably get a bit nerfed. Currently all attacks steal gold I think, mixing none stealing attacks into it could help.
I assume with static "corpses" you mean just not animate some enemies? Not sure if the mix of animated and non animated enemies would look good.
Just to make sure we're on the same page, when you mention the bleed, you mean the idea where enemies apply DoT with an attack, right?
With "corpses" I more meant that enemies, instead of simply vanishing when defeated, would be replaced with a non-animated, non-interactive "dead" image. Kind of like Darkest Dungeon, if you've played it (except the position is unimportant so the corpse is just visual).
My reasoning is that "corpses" would kind of be the next best thing to have instead of enemy tf.
Sure, it wouldn't have the same thematic relevance as inflicting your enemies with the same thing they inflict upon you, but at least it rewards the player with lewds without multiplying the animation number.
