World of Warcraft®

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.

While off cooldown, your Dark Soul ability passively grants you 10% of the active effect, but reduces the power of Dark Soul by 10%.

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