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%.

Your Soul Shards no longer display while out of combat.

Splits your Shadow Bolt into three smaller attacks.
