Conserving Weapon Fusion
Weapons with the conserving fusion preserve their ammunition and charges after a miss. When you miss with a ranged attack roll, your charge or ammunition is not consumed, as though the weapon had never been fired. This fusion does not prevent your weapon from malfunctioning or breaking as a consequence of your attack. Only weapons that use arrows, batteries, darts, flares, grenade arrows, mini-rockets, rounds, or scattergun shells as ammunition can benefit from a conserving fusion.
