From HGWiki

Orcus is typically described as having the head and legs of a goat, although with ram-like horns, a bloated body, bat-like wings, and a long tail.

Orcus cares for nothing save himself—not even his devotees and undead servants—and focused only on spreading misery and evil. One of his most identifiable symbols was the artifact known as the Wand of Orcus, a skull-topped wand with the power to slay any living being. Orcus also wielded a powerful artifact known as the Orcusword.

Overview

Thanatos is the 113th layer of the Abyss. It is a frozen necropolis, cold plane of ice, with thin air, black, moonlit sky and a place that belongs as much to the undead as to the tanar'ri.

Main threats

• Cold Electrical Negative are the most common damage types.
• Fire Divine is necessary for mini-bosses which are Balors.
• All Undead here heal on Negative making this an unsuitable damage type for your primary weapon.

  • No noteworthy special abilities, but quite resilient: Use Piercing, Positive and Fire, summons more creatures frequently including Balor aplenty.

Orcus as a Prince Strategy

Spoiler Warning!

Similar to the non-prince Orcus fight although use of +16 enhanced weapons is required to pierce his damage resistance, however (and this is probably the biggest however you'll encounter in the mod!) he spawns with his high priest Quah-Nomag who's sole purpose is to cast Greater Restoration repeatedly over and over on Orcus to heal and restore any vulnerabilities that may have been inflicted on him. If you are unable to stop him doing this either by counterspelling or multiple contiguous Death of Magic Epic spells you Will lose this fight. Quah-Nomag is relatively small and can be difficult to target in the mobs that spawn and he has a habit of positioning himself underneath Orcus himself making counterspelling more tricky especially if you get disrupted and have to re-target. Effective use of Epic and Paragon spells is critical to winning this fight as you need to keep your counterpeller up and active not dominated or dead.
