This skill steals life from a victim and provides it to the attacker (similar to that provided by devourers), it:

• Drains life at 50% but does not use your weapon (compared to 3% for life stealing which does).
• Wont work against something undead or not alive (e.g. golems).
• Is protected from by both Drain and Life_stealing resistance (which ever is higher).
• Wraiths restore food through life stealing too (which is otherwise very slowly used up)
