It's a necromancer icon that gives -50hp. I have an extra if you want to buy it from me... I've seen these go for huge ranges in price, so leave an offer if you want... or just do the pain in the ass long quest and get one as a reward.
AFAIK there are no hp reducing one handed weapons, only icons get -hp. It is possible to get random blue/purp/gold drops with -hp... but I've only seen those get up to "32" once... not the -50 from the mission one. So I suppost theoretically you could get one higher, but it would be extremely rare. And yes, as of now the 55 hp build is the lowest.
well all i was sayin is that i once got an axe that said 15%>50 -15health...... so i thought there were more like this... had i know the use i would have kept it but instead i sold it to merchant for 244g lol
that is no lie... i am about 90% sure it had a negative health affect.... i will admit i could be wrong, but im pretty sure it did, it was a golden axe
