Abyxcos

Abyxcos is one of the always spawned bosses when you zone into Sleeper's Tomb. He is located on the 2nd set of ramps leading down to Kerafyrm. Killing Abyxcos has an approximately 1 in 35 chance of spawning Real Abyxcos. Abyxcos drops a considerable amount of Essence of Norrath if farmed consistently, with this common loot being Tier essences and TOFS Essences 1-4

Abilities

Abyxcos has one ability he does one time per fight, an unsurviveable area-effect direct damage spell, which he always triggers almost immediately upon being pulled. This effect must be mitigated.
