I think she's already got an ability to reduce max HP, one of her rares that costs 6 or 5 upgraded and shaves off 1/4th of their max and gets lowered in cost every time it gets drawn.

I can't remember Ethereal cut off hand, is that just one of those life Loss cards? Because those things are usually great as is since they pierce enemy shields most of the time [Some modders have it say life loss but it still hits the shields though :d ]

Max HP damage is useless unless it is done on first round, that is why shorten life have so big cost at start. The only monsters that heal themselves are the time eater and the awakened, and the last one reset it to a bigger value after reborn (otherwise i would remove life swap from the game)

Ethreal Cut/Swipe are powerful because cuts through everything, that is why i made it don't interact with Str/Vulnerable, as an extra Weak.

Thank for responding, just thought that would a thematic and unique mechanic, though guess if it happens, it would be for her boss. Thanks though, and also, I really like the minimalistic art of our scythe lady
