Abilities that grant a power increases (such as Evocation) were changed to guarantee a consistent number of ticks of regeneration at the increased level. For Evocation, this means that as soon as the spell is cast, a single tick of mana regeneration will be awarded at the normal level, then exactly 2 seconds and every 2 seconds after, the 1500% of mana regeneration will be returned, guaranteeing a full 4 ticks of increased regen every time. Previously, with unfortunate timing, increased mana would be returned on only 3 ticks.
Animation changed to the new cyclone spell effect.
Patch 1.11.0 (2006-06-19): This spell is no longer a talent, and can instead be trained at Level 20 from any mage trainer. Cooldown reduced to 8 minutes, down from 10 minutes.
