Slingshot
The slingshot is a simple weapon and an attack with it deals d4 pierce damage. This weapon has three properties: Aimed (10m), Ammo (stone), and Two-Handed.
Aimed. You can't use this weapon to attack a target within 1 yard of you unless using it as an improvised weapon. As a ranged attack, you can shoot this weapon at a target within 12 yards of you. If you are skilled with the weapon you can shoot a distance up to 36 yards, but when targeting beyond 12 you don't add your skill level to the attack roll. Add either your Dexterity or Perception to attack and damage rolls with this weapon, replacing Strength.
Ammo. This weapon comes with 20 stones, each of which is a petty item. Each attack with this weapon consumes one stone.
Two-Handed. You can only attack with this weapon while wielding it in two hands. You can still hold the weapon without attacking using only one hand.
