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.
AC 36; Fort +22, Ref +28, Will +25
HP 300; Immunities fear effects; Weaknesses holy 15
+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
Trigger A creature within the chakanaj's reach attacks its host
Requirements The chakanaj is Bonded with a Host
Effect The chakanaj makes a leg Strike against the triggering creature. If the chakanaj was Impersonating clothing when it makes this strike, the Impersonation ends.
Speed 10 feet, fly 40 feet
Melee Leg +29 (agile, finesse, magical, unholy), Damage 3d6+14 slashing plus 2d6 spirit
Requirements The chakanaj is adjacent to a willing creature
Effect The chakanaj enters the space of the creature (thereafter called its host) and covers a suitable surface on the host, such as the face or back. The chakanaj occupies the same space as its host and moves with its host. It doesn't impair the host's senses or movement. While worn, the chakanaj establishes a constant Share Life effect with its host. Attacks that target the chakanaj target the host instead, but use the higher AC or saving throw values between the chakanaj and the host. Area effects apply to both the chakanaj and the host, as normal for an area of effect.
Interpose
Requirements The chakanaj is Bonded with a Host
Effect The chakanaj interposes itself between the host and its foes, granting its host a +2 circumstance bonus to AC until the start of the chakanaj's next turn.
Effect: Interpose
Peel Away(concentrate, move)
Requirements The chakanaj is Bonded with a Host
Effect the chakanaj removes itself from its host, peeling off the host's body and enters an adjacent space.
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.
