Ability

Ability

Circumstance: Trigger: The ostovite's bone chariot is destroyed;

+1 status to all saves vs. magic

 

Ability

Attack of Opportunity [Free Action]

Incalculable fangs only. Because the ouroboros contains an infinite number of snakes that act independently, its Attack of Opportunity is a free action (though it can still use only one per trigger).

 

Ability

Critical Failure

The creature is stupefied 3 and stunned, both for 1 minute.

 

Ability

Critical Success

The creature is stupefied 1 for 1 round.

 

Ability

Devour Tail

An ouroboros spend most of its life eating its own tail, which perpetually regrows at the same rate it's consumed. The ouroboros places its maw around the end of its tail and begins devouring its own body. While the ouroboros is consuming itself, its regeneration can't be suppressed, and it is immune to drained, enfeebled, fatigued, persistent damage, and sickened conditions. If any of these conditions is in effect when the ouroboros takes this action, the condition immediately ends. While eating its tail, the ouroboros can't make maw or tail strikes, and its Speeds are 50 feet. It continues devouring its tail even while dying, unconscious, stunned, or otherwise unable to act. To end this effect, the ouroboros must first be immobilized, then a creature must successfully Grapple it, which tears the maw free in addition to its normal effects. The ouroboros can also cease Devouring its Tail with a single action. Either of these tears the maw free of the tail, causing the stump to spill blood as described in sanguine spray.

Ability

Regenerative Blood

(contact, curse, incapacitation, poison, polymorph, primal, transmutation) The regenerative and transmutative properties of ouroboros blood regenerate and mutate a creature's body into ouroboros-like snakes. A creature already affected by regenerative blood is immune to additional exposure. Saving Throw DC 42 Fortitude; Maximum Duration 24 hours; Stage 1 regeneration 5 (deactivated by fire), slowed 1, and clumsy 2 (12 hours); Stage 2 regeneration 5 (deactivated by fire), slowed 2 and clumsy 4 (12 hours); Stage 3 The creature's body transmutes into a mass of writhing snakes, with the effects an 8th-level animal form spell but with an unlimited duration.

 

Ability

Sanguine Spray

When the ouroboros takes slashing or piercing damage, or when Devour Tail ends, blood gushes from the wound in a 15-foot cone. Each creature in the area takes 5d6 acid damage (DC 41 basic Reflex save). A creature that takes any damage is exposed to the ouroboros's regenerative blood (see below).

 

Ability

Success

The creature is stupefied 1 for 1 minute.

 

Ability

Unfathomable Infinity

(aura, incapacitation, mental, visual) 100 feet. The ouroboros is the embodiment of perfect infinity, and this concept pulls at the threads of mortal minds, desperately straining the limits of their comprehension.
