Special Abilities

Demon Hunter (Ex) A mythic ylyrgoi gains a +10 racial bonus on caster level checks to penetrate the spell resistance of any demon. Its attacks are treated as cold iron, epic, and good against demons.

Draining Maws (Ex) The fanged maws that cover a mythic ylyrgoi’s body automatically deal 2d4+4 points of damage plus 1d4 points of Constitution damage per round to any creature the mythic ylyrgoi constricts.

Fast Healing (Ex) A mythic ylyrgoi’s fast healing ability is equal to twice its current number of stingers (minimum fast healing 8). This fast healing applies only to damage inflicted on the mythic ylyrgoi’s body.

Gestation Aura (Su) A mythic ylyrgoi’s aura accelerates diseases and biological infestations, including pregnancies. All such afflictions and conditions active within the mythic ylyrgoi’s 30-foot aura have the onset time reduced to 1 round and the frequency reduced to 1/minute. Impregnated creatures inside this aura gestate completely in 2d4 minutes. As a swift action once per round, a mythic ylyrgoi can expend one use of mythic power to accelerate the frequency of all diseases and biological infestations, and the gestation period of impregnated creatures by 1 minute. If the affliction is still during its onset period, the onset period automatically ends, and the creature immediately suffers the affliction’s effects. Saves made due to the mythic ylyrgoi’s gestation aura ability do not count toward curing a creature’s original affliction, nor do failures count when determining consecutive saves.

Horrific Appearance (Su) Creatures that succumb to a mythic ylyrgoi’s horrific appearance become captivated for 1d4+1 rounds by the scintillating rainbow of colors that cascades across its form as hundreds of its eyes blink in an array of mind-bending patterns. A captivated creature takes no actions save to approach the mythic ylyrgoi, which it does not regard as a threat, via the most direct route possible and remain adjacent to it. If this path leads it into a dangerous area, such as through fire or off a cliff, that creature receives a second saving throw to end the effect before moving into peril. A victim that is attacked by the mythic ylyrgoi gets a new saving throw as a free action during each of the mythic ylyrgoi’s attacks to overcome the effect. A captivated creature’s ally may attempt to shake it free of the effect as a standard action, which provides the captivated creature another saving throw to end the effect.

Implant (Ex) A mythic ylyrgoi’s stingers contain eggs that it can inject into Medium or larger creatures when it strikes with a sting attack. The target can resist being implanted with a successful DC 24 Fortitude save. If the save is unsuccessful, the egg gestates and becomes a fetal shoggti qlippoth that begins consuming its host after the onset period. When the host is reduced to 0 Con, a shoggti bursts from the host’s body in a shower of viscera and gore, as much a transformation of the host body as a destruction of it. Creatures killed in this fashion can only be restored to life by miracle, wish, or similar magic. The egg or fetal shoggti can be cut free of the host’s body with a successful DC 25 Heal check, which takes 1 hour and deals 3d6 points of slashing damage to the host creature regardless of success or failure. Remove disease (or any similar effect; DC 24) also kills an implanted egg or fetal shoggti.

Ylyrgoi Egg: Infestation—injury; save Fort 24; onset 1 day; frequency 1/day; effect 1d4 Con damage until host dies, then a shoggti emerges. When the shoggti emerges from the host, it is stunned for 1 round. The save DC is Constitution-based.

Regenerate Stinger (Ex) When a mythic ylyrgoi’s stinger is severed, two stingers regrow in 1d2 rounds. A mythic ylyrgoi cannot have more than twice its original number of stingers at any one time. To prevent new stingers from growing, at least 16 points of acid or fire damage must be dealt to the stump (a touch attack to hit) before they regrow. Attackers must overcome the mythic ylyrgoi’s resistance to these types of energy to inflict this damage. Acid or fire damage from area attacks can affect stumps and the body simultaneously. A mythic ylyrgoi doesn’t die from losing its stingers until all are cut off and the stumps seared by acid or fire. As an immediate action, a mythic ylyrgoi can expend one use of its mythic power to immediately regrow two stingers from a stump.

Stunning Shriek (Su) A mythic ylyrgoi can emit a stunning shriek in a 30-foot-radius burst centered on itself as a standard action. All creatures in the area, other than the mythic ylyrgoi, must succeed on a DC 24 Fortitude save to avoid being stunned by intense pain for 1 round and deafened for 1d6 rounds. A mythic ylyrgoi can expend one use of mythic power to emit a stunning shriek as a swift action. The save DC is Constitution-based

Tongues (Ex) All of the maws that cover a mythic ylyrgoi’s body can extend a thin, sticky tongue. These tongues are secondary attacks with reach equal to twice the mythic ylyrgoi’s normal reach (30 feet for a huge mythic ylyrgoi). A tongue deals no damage on a hit, but can be used to pull Large or smaller creatures closer. While it has a tongue attached, a creature cannot move away from a mythic ylyrgoi. As a standard action, a creature can escape from a tongue with a successful DC 20 Strength check, DC 25 Escape Artist check, or by severing the tongue. A tongue has AC 21, 12 hp, and DR 10/epic, lawful, and slashing. At any one time, a mythic ylyrgoi can only use a number of its tongues equal to its current number of stings.

As a free action, a mythic ylyrgoi can chew through a tongue that has caught a creature. Severed from the mythic ylyrgoi’s maw, the tongue wraps around the captured creature and attaches to the ground or other nearby hard surface or object (such as a wall, large rock, or tree). The creature is no longer subject to that tongue’s pull attack but must succeed at a DC 24 Reflex save or be entangled for 1d6 rounds. Even with a successful save, the creature can move only at half speed. Huge or larger creatures are unaffected by this attack. A flying creature is not immobilized, but it must succeed at a DC 24 Reflex save or be unable to fly (assuming it uses wings to fly) and fall to the ground. The save DC is Constitution-based. A mythic ylyrgoi regenerates a severed tongue over the course of 24 hours.

Ylyrgoi Traits (Ex) A mythic ylyrgoi can be killed by severing all of its stingers or slaying its body. Any attack that is not an attempt to sever a stinger affects the body, including area attacks or attacks that cause piercing or bludgeoning damage. To sever a stinger, an opponent must succeed at a sunder attempt with a slashing weapon. A stinger is considered a separate target with hardness 10 and hit points equal to the mythic ylyrgoi’s HD; slashing weapons that are both epic and lawful ignore the sting’s hardness. To sever a stinger, an opponent must inflict enough damage to reduce the stinger’s hit points to 0 or less.

Severing a stinger deals damage to the mythic ylyrgoi’s body equal to the mythic ylyrgoi’s current HD. A mythic ylyrgoi can’t attack with a severed stinger, but takes no other penalties. If a severed stinger remains within the gestation aura of a mythic ylyrgoi for 1 round, one of the eggs it contains gestates. The gestation period is 1 day; if the severed stinger remains within the aura for another round, however, it transforms into a shoggti in an explosion of ichor.

Ylyrgois are enormous, pale-blue, hydra-like worms that writhe up from the depths of the Abyss to slay demons and use demon corpses to spawn more qlippoth. Their serpentine bodies are 30-feet long and riddled with hundreds of tiny, fanged jaws interspersed with blinking eyes, each a color of the rainbow. The shrieking maws covering their bodies begin devouring any creature caught in an ylyrgoi’s coils even as it is still being crushed to death. Each of these mouths can also extend a thin, sticky blue-gray tongue that an ylyrgoi uses to pull its prey within range of the dripping black stingers that, instead of heads, top each of its 10-foot long necks. They weigh 2,000 pounds.

The ylyrgoi’s purpose on the Abyss is the extermination of the demonic scourge. They contribute to this goal not only by efficiently slaying most demons they encounter, but by infesting their opponents’ bodies with eggs that swiftly gestate into fetal shoggtis. Typically, if the demon survives the encounter with the ylyrgoi, the fetal shoggti feeds on the demon for several days before finally emerging, shortly after its host dies, as a fully-grown shoggti. If the demon doesn’t survive the encounter, the transformation from corpse to shoggti is swifter, occurring after around 2 days. The ylyrgoi is a disinterested mother; it doesn’t care for the shoggtis, but nor does it consume them.

Advancing an ylyrgoi by increasing its Hit Dice also gives it one additional stinger and a +2 increase to its natural armor for each added HD, in addition to the standard increases to the ylyrgoi’s statistics. An ylyrgoi’s CR increases by +1 for each Hit Die it gains.

Habitat and Society
Ylyrgois are solitary creatures, and typically remain in the deepest qlippoth-held layers of the Abyss. Following their recent discovery, it is theorized that the fates of the poor souls enslaved by shoggtis in other realms and dragged back to the Abyss may be as offerings to the shoggtis’ ylyrgoi progenitors.
