Warhammer Fantasy Roleplay First Edition Wiki

Ballistic Skill (BS) dictates a character's ability to use missile weapons, to throw an object, or (in the case of some creatures) to spit venom.

Like WS, this is expressed in percentage terms of 01-100% and the higher the BS, the easier it is to hit a target.

For tests, BS reflects accuracy in shooting and throwing; it might be used to determine the accuracy of any throw in a non-combat situation, such as a game of darts.
