World of Warcraft®

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

You restore 20% of your total health after you kill a target in Demon Form that yields experience or honor.

Teaches you the ability Imp Swarm.
Requires Demonology.

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.

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

Your Soul Shards no longer display while out of combat.
