Channel Energy (Su) A caen channel energy as a 10th-level cleric, choosing each time it uses this ability to either channel positive energy as a good cleric or channel negative energy as an evil cleric. A caen does not require a holy or unholy symbol to channel energy, instead holding forth its tail.
Create Spawn (Su) Any corporeal creature that dies while grappled by a caen rises immediately as a fast plague zombie. This zombie is not under the caen's control, but will not attack the caen unless somehow controlled by another creature and directed to do so. Each time a caen creates a plague zombie in this manner, the caen heals 1d6 points of damage per Hit Die of the creature that died and became a zombie.
