Splinter Crossbow Bolts (20)

This magical bow can split arrows as you fire it, allowing you to target two creatures within 10 feet of each other. When you use the bow in this way, you make only one attack roll, which applies to both targets. If the attack hits at least one of the targets, roll damage normally; each target takes half the amount of damage rolled (rounded down).

Ammunition: You can use a weapon that has the ammunition property to make a ranged attack only if you have ammunition to fire from the weapon. Each time you attack with the weapon, you expend one piece of ammunition. The ammunition of a firearm is destroyed upon use. Drawing the ammunition from a quiver, case, or other container is part of the attack (you need a free hand to load a one-handed weapon). At the end of the battle, you can recover half your expended ammunition by taking a minute to search the battlefield.
