Zoltun kulle

Zoltun Kulle  was one of the founders of the Horadrim, but turned towards the side of darkness after the creation of the Black Soulstone. He was the most powerful mage in all of Sanctuary, and the Horadrim realized this. The forces of Sanctuary then banded together and severed Kulle's body into two jars of blood, his head, and his body.

The Horadrim
Kulle was one of the founding members of the Horadric order with the assistance of six other powerful mages. He had a great talent in alchemy, and was a member of the Ennead Clan. After the capture of Mephisto, Diablo, and Baal, Zoltun Kulle began an invention which could imprison the Great Evils and the angels of the High Heavens, the Black Soulstone. The creation of it drove him mad, and all he could think about was completing the soulstone. Jered Cain then realized that Kulle has learned the secrets of immortality; Cain and the Horadrim hunted down Kulle and killed him, severing Kulle's head from his body and collecting two jars of his blood. These artifacts were then hidden in vaults under the Desolate Sands.

The Final Lords of Hell
Belial and Azmodan began to plot to overtake humanity. A group of nephalem battled their way through the Legion, and meet a witch, Adria, who told them of a soulstone that could trap all the Great Evils inside of it. However, they would need to find the head, blood, and body of Zoltun Kulle in order to find it. After finding the blood and fighting through the Archives of Zoltun Kulle, they came across the soulstone chamber. Kulle double-crossed the group, and the nephalem were forced to kill Kulle once and for all and take the Black Soulstone for themselves.

Kulle is one of the six handpicked Boss monsters to feature an Uber appearance. His Uber appearance himself has changed little in strategy, but there are a couple things to be aware of. Firstly, he has the aid of the Savage Behemoth, which can cause trouble even for the best equipped of heroes. Secondly, his Slow Time bubbles are much worse compared to his canon encounter in Act II; they mercilessly destroy a hero's attack speed and movement, leaving him/her relatively helpless, and should therefore be escaped from as soon as possible.
