World of Warcraft®

Your Corruption spell will heal you for 0.5% of your maximum health when dealing damage.

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.

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

If you use Demonic Leap while falling, you slam into the ground rapidly and will not die from falling damage.

Your soulwell glows with an eerie light.

Your Felguard will equip a random two-handed axe, sword or polearm from your backpack.
