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.

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

Your Eye of Kilrogg is no longer stealthed and can now place your Demonic Circle. The casting Warlock must be within line of sight of the Eye of Kilrogg to place the Demonic Circle.

In addition, the movement speed of your Eye of Kilrogg is increased by 50% and allows it to fly in areas where flying mounts are enabled.
