Incanter's Ward is a talentedmage ability, available at level 90. This talent envelopes a shield around the mage, turning a set amount of damage absorbed into a hefty mana gain. The talent's passive effect increases mana regeneration and spell power while Incanter's Ward is off cooldown.
Patch 5.3.0 (2013-05-21): Now allows the Mage to gain up to a maximum of 15% increase to spell damage, down from 30%, but the effect now lasts 25 seconds, up from 15 seconds.
Hotfix (2013-03-15):Incanter's Ward is no longer transferred to a Mage who Spellsteals it, but is dispelled from the target.
Patch 5.2.0 (2013-03-05): Can now be removed by magic dispels.
