Chakanaj

Telepathy 100 feet (aura, magical) — A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.

Constant Spells — A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

+4 to Perception to Sense Motive —

Ear for Secrets — A chakanaj knows when a creature within 30 feet lies unless that creature critically succeeds on its Perception check to lie to the chakanaj. This ability doesn't reveal the truth.

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

Retaliate —

Bond with Host (concentrate, move) —

Interpose —

Peel Away (concentrate, move) —

Skip Between (divine, teleportation) — The chakanaj sahkil moves from the Material Plane to the Ethereal Plane or vice versa, with the effects of Ethereal Jaunt except the effect has an unlimited duration and can be Dismissed. A summoned sahkil can't use Skip Between.
