Reduces target's mana by X and charges you with Arcane energy for 10 min. This effect stacks up to 3 times.
A blood elfracial ability used in combination with Arcane Torrent. This ability was removed in patch 3.0.2., partly due to lore reasons - in the closing hours of Burning Crusade the Sunwell was reignited and began to feed the elven addiction for magic again, thus removing the need to tap mana from other creatures. The practical reason however was that while it had its uses, such as a ranged cornerpulling tool for blood elf paladins, the mechanic to maintain three charges to release arcane torrent was deemed too much of a hassle, especially in raids and other content that required more attention to other functions. It is still referenced by Emotes done by female blood elves.
