Bythos

Creature 16 (uncommon) — aeon, monitor

The bythos is a guardian of space and time and ever seeks those who misuse planar and temporal magic. A bythos is a roughly humanoid creature with four arms and a body made of swirling clouds and mist. Despite their appearance, their body feels like dry stone. A bythos seeks out paradoxes caused by irresponsible planar or dimensional travelers and repairs breaches where the barriers between planes have become thin or damaged. If the mortals responsible remain in the area and cannot be convinced

Abilities

Envisioning — When a bythos conveys information, it does so wordlessly through psychic projections. This acts as Telepathy with a range of 100 feet but is understandable to all creatures regardless of whether they have a language. The meaning to non-aeons can be vague and is often mysterious. A bythos can use this ability to communicate flawlessly with any other aeon on the same plane.
+1 Status to All Saves vs. Magic
Regeneration 15 (Deactivated by Spirit) — Regeneration
Confusing Gaze (aura, divine, emotion, incapacitation, mental, visual) — 30 feet. A creature that ends its turn in the aura must attempt a DC 34 Will save. If it fails, it's Confused for 1 round (or 1d4 rounds on a critical failure).
Temporal Reversion (fortune) —
Aging Strikes (divine) — The bythos make two fist Strikes against a single target. If both Strikes hit, the target attempts a DC 37 Fortitude save. Creatures that don't get weaker with age or don't age are immune (GM's discretion). If a creature becomes clumsy 4, drained 4, and enfeebled 4 due to Aging Strikes, it dies of old age. **Success** The creature is unaffected. **Failure** The creature becomes Clumsy 1, Drained 1, and Enfeebled 1, or increases each of these conditions by 1. This effect is cumulative with other aging strikes from bythoses, to a maximum of clumsy 4, drained 4, and enfeebled 4. **Critical Failure** As failure, but the creature becomes Clumsy 2, Drained 2, and Enfeebled 2, or increases these conditions by 2.
Focused Gaze (concentrate) — The bythos focuses its gaze on a creature it can see within 30 feet. The target must attempt a save against the bythos's confusing gaze. A bythos can't use this ability against the same creature more than once per turn.
Temporal Flurry — The bythos makes four fist Strikes. Its multiple attack penalty increases normally with each attack.
Temporal Strike (divine, incapacitation, teleportation) — The bythos touches a creature or object to displace it from time. The target attempts a DC 37 Fortitude save. **Critical Success** The target is unaffected. **Success** Time flows around the target; the target is Slowed 1 for 1 round. **Failure** The target disappears from the present moment and reappears in the same location 1d4 rounds later as if no time had passed for it. If a creature or object occupies that space when the target returns, the target appears in the closest available space to its original location. **Critical Failure** As failure, but the target is Slowed 1 for an extra 1d4 rounds after it returns.
