Cerberus

Cerberus is a level-318 Giant Hellhound Boss that requires both a Slayer level of 91 to kill and a slayer task of Cerberus itself or Hellhounds. Cerberus is located deep beneath the Taverley dungeon near the Hellhound area which is found beyond the and Poison spider areas.

He has a slim chain of dropping Primordial, Eternal and Pegasian crystals, which can upgrade the current best-in-slot boots for melee, magic, and ranged. In addition, he also has a slim chance of dropping a Smouldering stone that, when combined with a Dragon axe or Dragon pickaxe, can add a "heat element" to the tools, allowing the Dragon axe to become an Infernal axe and the Dragon pickaxe to become and Infernal pickaxe.

There is also a slim chance to obtain a Hellpuppy pet.

It has 690 health and spawns shades, there is no way found to safespot the shades so far.
