ウロボロス Ouroboros
Ouroboros are the embodiment of eternity. Though they're prevalent as a symbol, often scrawled across the margins of alchemical tomes, few know that the beasts actually exist in the Astral Plane , where they fly through the silvery-gray void like a serpentine wheel. The ouroboros is usually depicted as a snake devouring its tail. This circular symbol is synonymous with infinity, self-sufficiency, and eternal unity.
An ouroboros' form exemplifies the unfathomable concepts of forever. Its undulating body is composed of smaller serpents, who are in turn composed of ever smaller serpents, continuing indefinitely. These smaller components are recycled as the ouroboros devours its tail, existing in a perpetual, cyclical process of creation and destruction. It is a massive creature, forming a loop roughly 50フィート in diameter and weighing hundreds of tons.
An ouroboros's most striking feature is its ability to almost instantly grow new flesh and heal from nearly any wound. This profound regenerative ability comes in part from an ouroboros's magical blood, which is rumored to have many miraculous properties.
Through their inscrutable behavior suggests that an ouroboros is mindless, the creatures boast crude intellects and can understand speech, though they have no way to speak. They possess an instinctive, almost obsessive will to survive and defend themselves ferociously if threatened in even the slightest way. Often these perceived threats take the form of another creature simply existing within the ouroboros's line of sight, leading other Astral creatures to give these powerful beings a wide berth. The only creature an ouroboros reliably ignores is another ouroboros, but they're so incredibly rare that these meetings occur only once an age.
Being entirely self-sustaining, an ouroboros rarely deigns to emerge from its consumption to engage with the Material Plane . Yet, the creature remains capable of inflicting tremendous devastation that far surpasses what it could wreak leveraging only its massive size alone. Left to its own devices, an ouroboros is likely to simply roam the Astral Plane in eon-spanning cycles, following some pattern too long and large for any mortal to even chart, much less fully comprehend. When conjured to the Material Plane, however, an ouroboros eagerly begins to initiate the cycle of renewal for which it is best known, beginning with that cycle's first step: destruction.

Unfathomable Infinity／Unfathomable Infinity (オーラ、無力化、精神、視覚) 100フィート. 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. When a creature ends its turn in the aura, it must attempt a DC 41 Will save. The creature is then temporarily immune for 1 minute.
大成功 The creature is stupefied 1 for 1 round.
成功 The creature is stupefied 1 for 1 minute.
失敗 The creature is stupefied 1 for 1 minute and stunned 3 .
大失敗 The creature is stupefied 3 and stunned, both for 1 minute.
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).
Sanguine Spray／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).
Where the blood falls upon ground、it coagulates into magical snakes that bite at anyone who passes. This is hazardous terrain deals 17 piercing damage and 5 poison damage to any non-ouroboros creature that moves through the square or ends its turn there. A creature that avoids all the piercing damage doesn't take the poison damage. After 1 hour、a blood patch permanently becomes a living snake、typically an emperor cobra .

While the ouroboros is consuming itself, its regeneration can't be suppressed, and it is immune to drained, enfeebled, fatigued, persistent damage, and sickenedconditions. 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フィート. 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.
