A bola is a superior one-handed melee weapon in the flail weapon group.[Dr368:64]

A bola is a light thrown weapon, so a character can throw it as a ranged attack.

The Executioner has proficiency with the bola as a class trait, but any character can become proficient by taking a Weapon Proficiency feat. Martial classes may also gain proficiency with the Bola Training feat.
