Easy to Call A sahkil's level is considered 2 lower for the purpose of being conjured by the planar binding ritual (and potentially other rituals, at the GM's discretion), but it is always free to attack or leave instead of negotiate unless the primary caster's check is a critical success.

Feed on Fear The kimenhul regains 30 Hit Points at the start of its turn as long as any frightened creature is within 100 feet of it.

Eternal Fear [>>] (divine, emotion, enchantment, fear, incapacitation, mental) The kimenhul contorts its faces and presents itself to its enemies in a terrifying and traumatic display that causes lingering fear. Each creature within 100 feet that can observe the kimenhul must make a DC 42 Will save. They are then temporarily immune for 10 minutes. Critical Success The target is unaffected.Success The target becomes frightened 3.Failure The target becomes frightened 3 and is fleeing as long as it's frightened. Even after recovering from the initial experience, the trauma is lodged in the target's mind for 1 year. Once per day, the kimenhul can communicate telepathically with the target for 1 minute as long as both creatures are on the same plane. Any time a creature under the effect of Eternal Fear is in a stressful situation (such as combat or intense social pressure), they must succeed at a DC 11 flat check or become frightened 2. While Eternal Fear lasts, the target always becomes fleeing as long as it's frightened, regardless of the source of the fear. The target can attempt a new saving throw each week to remove these effects, but they can otherwise be removed only by powerful magic such as wish.Critical Failure As failure, but the effects are permanent and the target doesn't get to attempt a weekly save to end the effect.

Frightening Flurry [>>] The kimenhul makes one jaws Strike and two claw Strikes against a single target, in any order. The target becomes frightened with a condition value equal to the number of Strikes that hit it, to a maximum of frightened 3 if all three Strikes hit.

Rend [>] (claw) (page 306)

Skip Between [>] (conjuration, divine, teleportation) The sahkil moves from the Material Plane to the Ethereal Plane or vice-versa, with the effects of ethereal jaunt except that the effect has an unlimited duration and can be Dismissed. A summoned sahkil can't use Skip Between.

Snatch Between When using Skip Between, the kimenhul can bring along any creatures it has grabbed.

Unsettled Mind Any creature affected by any of a kimenhul's mental spells or abilities becomes stupefied 3 for the duration of that effect and for 1d4 rounds thereafter.
