Lifesteal

The Lifesteal bonus is an offensive stat bonus that shows the player what percentage of the damage they deal is returned to them as health. Unlike previous mechanics similar to it, the bonus is applied on every hit and works with every combat style. For example, if a player has a lifesteal bonus of +15% and deals 20 damage to their target, then they are healed for 3 hitpoints.

Weapons and Equipment

Blood spells in the Ancient spellbook also provide the player with a lifesteal bonus but do not list the percentage on the equipment screen.
