Your Moonkin Aura also causes affected targets to gain X% haste and you to gain Y% of your spirit as additional spell damage.
Improved Moonkin Form is a talent in the Druid'sBalance tree, you will need to spend 34 points in Balance to max it. Improved Moonkin Form gives everyone in your party and/or raid 3% haste and grants you 30% of your Spirit as Spell Power while in Moonkin Form when maxed.
The haste from this talent does not stack with other talents that grant 3% spell haste or more. It will also overwrite any other raid wide spell haste buff that is lower than 3%.
Tips and Tactics
Because PvP gear generally doesn't have very much spirit on it, this talent is rarely used in pure PvP builds.
