Influence Effects

Multiplicity Nyogtha can exist in multiple places at the same time. When its influence is first established, only one avatar of Nyogtha is active. As that avatar feeds, Nyogtha gains the ability to manifest more than one avatar at the same time, appearing at any point it desires within the area of its influence. See the statistics for Nyogtha’s avatar below for what can cause it to manifest a new incarnation.

Special Abilities

Duplication (Ex) Whenever Nyogtha kills a creature by reducing it to powder (either with its oblivion ability or after swallowing a creature whole), a new avatar of Nyogtha manifests within the Great Old One’s area of influence at any point chosen by the Great Old One. This duplication effect can only occur once per day, regardless of how many avatars are currently active. Up to 10 avatars of Nyogtha can exist at a time in a single area of influence.

Oblivion (Su) Whenever a creature takes damage from one of Nyogtha’s bites, there’s a chance that the victim is fully subjected to the impossibility of the Thing that Should Not Be. This chance is equal to 2% per bite when Nyogtha’s influence is at stage 1, 5% per bite when the influence is at stage 2, and 20% per bite when the influence is at stage 3. The chance of being subjected to oblivion doubles if the bite is a successful critical hit. If the victim is so subjected, it must make a successful DC 27 Fortitude save to resist taking an additional 100 points of damage. If this attack reduces the creature to 0 hp or less, it is slain immediately and reduced to powder. The save DC is Charisma-based.

Swallow Whole (Ex) A creature swallowed whole by Nyogtha takes 20d6 points of damage per round. If this damage reduces a creature to 0 hit points, it is immediately slain and reduced to powder. If a creature manages to cut its way out of Nyogtha, the Great Old One’s body flows together after the victim escapes— additional swallowed victims must cut their own way out.


Nyogtha is called the “Absence of Light” and the “Thing That Should Not Be.” While it takes a definite shape (if malleable), it is a negativity—a sort of hole in creation. It is covered with blind mouths and sharp teeth, though its utterly black outline seems blurry to mortal eyes.

Nyogtha inhabits the depths of a planet normally, but it has no fear of the surface. Light does not harm it—instead, Nyogtha absorbs any light directed at it. Worshipers of Nyogtha make their shrines at entrances to the underworld or build subterranean complexes for their god to roam.

Nyogtha in Combat

Nyogtha can exist in multiple places at the same time. Thus, while Nyogtha assaults enemies deep within its lair, it can also block the entrance to prevent them from escaping, and attack their home town all at once. If one of its avatars is killed (not an insuperable task), there are many more—indeed, Nyogtha can replicate itself infinitely.
