Flicker An onryo's erratic movement makes them difficult to target. If an onryo moves at least 10 feet during a move action, they gain concealment until the start of their next turn.

Onryo's Rancor [>] (curse, enchantment, mental, occult) Requirements The onryo's last action was a successful claw Strike; Effect The onryo attempts to instill its need for vengeance into the creature. The onryo, with their touch, casts a 5th-level geas on the creature they hit (DC 30 Will). On a failure, it's forced to seek and slay loved ones of the onryo's wrongdoer and anyone who attempts to defend them for up to one week. On a critical failure, the duration is 1 month and the creature gains Onryo's Rancor, which it's also compelled to use by the geas. Regardless of the outcome, the creature is temporarily immune to Onryo's Rancor from this individual for 1 year.

Vengeful Suffocation[two-actions] (incapacitation, occult, necromancy) Frequency once per hour; Effect The onryo channels their boundless resentment, manifesting it as a tangled clump of wet hair, a clot of rancid swamp mud, or other disgusting mass of matter in the throat of a creature within 30 feet. The creature must attempt a DC 32 Fortitude save. Critical Success The creature is unaffected.Success The creature becomes sickened 1.Failure The creature becomes sickened 2.Critical Failure The creature becomes sickened 3 and the mass fully blocks the creature's airway. The creature begins suffocating (Core Rulebook 478)
