Ancient Kaa the Soulless is a Super Unique Unraveler found in Tal Rasha's Tomb. He can be spawned in any one of the false tombs, and not necessarily next to the treasure trove. He is never spawned in the true tomb. His tomb is much larger than the other five false tombs. There is no quest or special reward associated with Kaa, but he has achieved semi-legendary status in the game thanks to the sheer number of minions he can spawn with in Hell, and is sometimes sought by bold players, like a tourist attraction that can kill you.
His special abilities make him one of the more dangerous monsters.
- From his nature of not appearing in Tal Rasha's real Tomb but in one of the other tombs in the Canyon of the Magi, where the mummified bodies of seven of the greatest Horadrim were buried, and the sheer number of special abilities he possesses, Kaa appears to be one of the seven who were originally buried there.
- His name is derived from the Egyptian word ka, which means lifeforce. Kaa the Soulless is essentially a description of what he does with the undeads: the ancient lifeforce that controls the soulless.
- The tomb, in which the Ancient Kaa appears, is considerably larger than the other false tombs, just like the true tomb. The monster always appears in a room with a crescent-like arrangement of braziers on the floor.
