Chokers speak Undercommon.

Combat

A choker likes to perch near the ceiling, often at intersections, archways, wells, or staircases, and reach down to attack its prey.

Haste (Su): Although not particularly dexterous, a choker is supernaturally quick. It can take an extra partial action each round, as if affected by a haste spell.

Improved Grab (Ex): To use this ability, the choker must hit an opponent of up to Large size with a tentacle attack. If it gets a hold, it can constrict.

Constrict (Ex): A choker deals 1d3+3 points of damage with a successful grapple check against Large or smaller creatures. Because it seizes victims by the neck, a creature in the choker's grasp cannot speak or cast spells with verbal components.
