A couatl is about 12 feet long, with a wingspan of about 15 feet. It weighs about 1,800 pounds. Couatls speak Celestial, Common, and Draconic, and also have the power of telepathy.
A couatl uses its detect thoughts ability on any creature that arouses its suspicions. Since it is highly intelligent, a couatl usually casts spells from a distance before closing. If more than one couatl is involved, they discuss their strategy before a battle.
Constrict (Ex): A couatl deals 2d8+6 points of damage with a successful grapple check.
Improved Grab (Ex): To use this ability, a couatl must hit a creature of up to two size categories larger with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can constrict.
Poison (Ex): Injury, Fortitude DC 16, initial damage 2d4 Str, secondary damage 4d4 Str. The save DC is Constitution-based.
Psi-Like Abilities: At will—aura sight, cloud mind (DC 15), detect psionics, read thoughts (DC 15); 3/day—mental barrier (2 rounds*), metamorphosis, psionic plane shift, thought shield (power resistance 19*). Manifester level 9th. The save DCs are Charisma-based.
*Includes augmentation for the psionic couatl’s manifester level.
Powers: A couatl manifests powers as a 9th-level psion. It can choose its powers known from the psion list and any one psionic disciple per couatl.
Change Shape (Su): A couatl can assume the form of any Small or Medium humanoid.
Ethereal Jaunt (Su): This ability works like the ethereal jaunt spell (caster level 16th).
Telepathy (Su): A couatl can communicate telepathically with any creature within 90 feet that has an Intelligence score. The creature can respond to the couatl if it wishes—no common language is needed.
