Starfall is a level 34 Balancedruid ability. It is a non-channeled area of effect spell that deals arcane damage to enemy targets in a target area within 40 yards of the caster. Although it does not cause an especially high amount of damage, it is a 8 second buff that does not require player interference, which allows a druid to have it up while casting other spells and abilities. The buff itself cannot be dispelled or spell stolen.
In PvP, Starfall becomes a valuable, albeit dangerous ability; when used against large crowds it can deal massive damage. It can also be a notable single target damage boost.
Starfall can be used on a boss fight to deal additional damage without much if any deficit, as the Global Cooldown used to cast the spell will be made up for in the amount of damage it deals, provided you are in range of the boss or mobs for the duration.
