World of Warcraft®

Requires Demonology.

Teaches you the ability Dark Apotheosis.

Dark Apotheosis
You imbue yourself with demonic energies, reducing physical damage taken by 13.85%, reduces magic damage taken by 15%, and allows the use of various demonic abilities.

In addition, Soulshatter becomes Provocation which taunts your target, Twilight Ward becomes Fury Ward which will absorb all schools of damage, Shadow Bolt becomes Demonic Slash, and Fear becomes Sleep.

Improves your demon's special abilities:

Your Imp's Firebolt cast time is reduced by 50% and fires in bursts of three.

Increases your Voidwalker's total armor by 10%.

Your Succubus's Seduction ability also removes all damage over time effects from the target.

When your Felhunter uses Devour Magic, you will also be healed for that amount.

Increases your Felguard's total health by 20%.

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

Increases the swim speed of targets affected by your Unending Breath spell by 20%.

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

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