Leech is a new minor attribute introduced in Warlords of Draenor. It causes players to gain health from a proportion of outgoing damage and a larger proportion of outgoing heals. Having 1% of Leech will let you gain 1% of the damage done as heal. Any Warlords-level gear looted or crafted has a slim chance of spawning with up to one minor attribute, including Leech.
