Benefit

When you take this feat, the range increment for daggers, darts, or shuriken increases by 10 feet when you throw them. In addition, as a standard action, you can throw two such weapons at the same time, provided you throw them at a single target within 30 feet. Both weapons use the same attack roll (with a ?4 penalty) to determine success and deal damage normally (but see Special). The weapons you throw do not have to be of the same type.

For every five points of base attack bonus you have above +6, you may add one additional dagger, dart, or shuriken to this attack, to a maximum of four weapons (in any combination) at a base attack bonus of +16. However, each weapon after the second adds a cumulative ?2 penalty on the attack roll, for a total penalty of ?6 for three weapons, and ?8 for four. Damage reduction and other resistances apply separately against each weapon thr

Special

Regardless of the number of weapons you throw, you only apply precision-based damage (such as sneak attack damage) once. If you score a critical hit, only the first thrown weapon deals critical hit damage; all the others deal regular damage. If throwing more than one type of weapon, you must declare which weapon you throw first before rolling damage.
