Mana Leech Support

For the game mechanic, see Leech.

Mana Leech is a support gem. Attack Skills supported by this gem will leech mana back to the player, based on how much damage they deal.

Unlike most sources of mana leech that only count physical damage, the leech from this gem considers all attack damage types when determining how much mana the attacker will gain. However, it will not work on damage over time effects.

This gem is one of the few ways to get mana leech on a skill that deals no physical damage. Other sources are Warlord's Mark and Pain Reaver.
