Missiles That Miss

With the exception of grenade-like missiles, missile weapons which miss the intended target are normally considered lost. However, if the weapon is fired into a melee where allies of the shooter are involved, and the attack misses, it may hit one of the allied creatures. The GM should decide which allies may be hit, and roll attacks against each until a hit is made or all possible targets are exhausted. These attack rolls are made with the shooter's normal attack bonus, just as if they intended to attack the allied creature. However, the GM must make these rolls, not the player. This rule is applied to attacks made by monsters, when appropriate. However, the GM still makes the rolls. This rule is intentionally vague; the GM must decide when and how to apply it based on the circumstances of the battle. It is recommended that no more than three allies be "tried" in this way, but the GM may make an exception as they see fit.
