I don't play the mod nowadays because of The Division and necromancers but I still like to see new content dropping to wiki and I wanted to contribute with an idea that is synergic to the new items.

Token of Death

+ All skills (based on life)
Health is maxed to %30
-50 to all resistances
Replenish life -300
%100 chance to cast level 120 12 bone spirits on death (can make a different concept for this, i was thinking about bone spirits bursting from body)

Should be a very rare drop from Malthael. Good players already know why this item would be so good.
