A set of 2-ball bolas consists of two heavy wooden spheres connected by lengths of cord. It is a ranged weapon used to trip an opponent. When you throw a set of bolas, you make a ranged touch attack against your opponent. If you hit, your opponent is tripped. If the opponent fails a grapple check versus your original attack roll, the opponent is grappled. Bolas only grapple Medium-size or smaller targets. The opponent can extricate itself from the 2-ball bolas with a full-round action. Your opponent cannot trip you when making a trip attack with the 2-ball bolas.
