Black Rock Sword (Azrael's)
 

Anyone from 1.1 or perhaps later remembers Azrael rping and pretending to use a sword called black rock sword (on Graal and chat) that sucked the soul out of people and stored it in a gem or something of that nature.

I think it would be cool if we had something like that, except instead of sucking someones soul it sucks their hp. Perhaps it would do less damage than a normal sword (5 damage perhaps) but heals the attacker hp equal to the total damage done after armour and resistances.
