Whistling Arrow

Ammunition with the whistling property creates a high-pitched sound after firing. This sound is audible for 300 feet from the ammo as it flies. Whistling ammo isn't heavier, but it catches the air in baffles to create its sound, so its maximum range is half normal. Whistling ammo deals bludgeoning damage.

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.
