I don't know if it's because it also is poison enchanted (does that always hit?) but due to Black Death's ability to reduce max hit points when they hit you, it just seems impossible for me to kill that guy — see screenshots: http://uppix.net/D2GWGZ.png ; http://uppix.net/JvLKON.png
Note: while not cursed, this character has 347 max hit points. Going down to 17 max is just o_O
Even if I try to attack him with a bow or spells, it will automatically shoot poison back at me, since it does even when he walks through one of my firewalls
Perhaps there should be a cap on their curse's effect, let's say for example they shouldn't be able to remove more than half your vitality or hit points.
This is exaclty the case from the list of suggestions, #75 which you said you dont understand (im sorry if it was beacuse of not proper enough english). Posion paddles werent mentioned there, but Flash and charged bolt were. Go back there and change your vote for #75 please.
And yes, im by the way for changing that, Black deaths should reduce max hp ONLY by melee attacks.
