Incanter's Absorption
Incanter's Absorption(3 ranks)
Arcane, Tier 4
When your Mana Shield or Mage Ward absorbs damage your spell damage is increased by 10/20% of the amount absorbed for 10 sec. In addition, when your Mana Shield is destroyed, all enemies within 6 yards are knocked back 12 yards.
Incanter's Absorption is a Magetalent in the Arcane tree. When you absorb damage with Mana Shield (original) or [Mage Ward], this talent turns a percentage of that damage into spell power, placing a buff on you. Also when Mana Shield is destroyed enemies within 6 yards are knocked back 12 yards.
Notes
This talent is very usefull on fights with static aura (especially arcane/fire/frost) which deals damage to player like Sindragosa. At 80 level with 250 ilvl gear Mana Shield and Mage Ward absorbs about 4000k. With simple math [(2*4000)*0,2]=[8000*0,2]=1600 You get 1600 bonus spell power for 10 seconds!
Also with recent changes in Patch 4.0.1, which added knockback effect this talent it's much more useful in PvP environment.
