Imp Swarm
Summons 5 Wild Imps from the Twisting Nether to attack the target.

The Wild Imps passive effect is disabled while Imp Swarm is on cooldown. Imp Swarm's cooldown is reduced by spell haste. Also increases Wild Imp's cooldown by 4 sec.

You receive 100% more healing from using a healthstone, but the health is restored over 10 sec.

Your Carrion Swarm no longer knocks targets back.

Your Felsteed and Dreadsteed can cross water while running and leave a trail of flames.

Your Hand of Gul'dan can now be targeted at a location.
