[20] Devourer of Souls (Horde Warlock):

Speak with Cazul in the Cleft of Shadow.

The time has come for you to learn more of the summoning magics. You will learn to summon a succubus, a creature of incredible mental powers. It can lull those of weak minds into its servitude--but have no fear! I feel certain that you will be equal to the challenge.

A succubus can only be summoned when baited with an item that represents great devotion and love. I leave it to you to find such an object.

A suggestion? Speak with Cazul... There seems to be little the ancient warlock does not know.

Cazul: I have dedicated my life to the search of flawless draenethyst spheres. A lifetime, tauren!

Cazul: Hm... Zarm. You are still new to your path, but I sense the possibility for greatness in you.

You were born with gifts, Zarm. See that they do not go to waste.
