Beckoning Dance [>] (concentrate, enchantment, incapacitation, mental, primal, visual) The riekanoy sways in a compelling fashion. Each non-fey creature within a 300-foot emanation that can see the riekanoy must attempt a DC 38 Will save. The effect lasts for 1 round, but if the riekanoy uses Beckoning Dance again on subsequent rounds, the duration extends by 1 round for all affected creatures. Once a creature succeeds at any save against Beckoning Dance, that creature is temporarily immune for 24 hours. Success The creature is unaffected.Failure The creature is fascinated and must spend each of its actions to move closer to the riekanoy, avoiding obvious dangers. If a beckoned creature is adjacent to the riekanoy, it stays still and doesn't act. If attacked by the riekanoy, the creature is freed from captivation at the end of the riekanoy's turn.Critical Failure As failure, but if attacked by the riekanoy, the creature can attempt a new save only at the start of its next turn, rather than being freed at the end of the riekanoy's turn.

Constrict [>] 3d10+12 bludgeoning, DC 41

Entangling Hair A riekanoy can have up to eight creatures grabbed within their hair at a time.

Waving Hair [>] The riekanoy attempts an Acrobatics check against each grabbed creature's Reflex DC. The riekanoy moves each creature they succeed against up to 10 feet and each creature they critically succeed against up to 20 feet. This movement must all be within reach of its hair.
