Alchemist Bolts

The tips of these bolts are hollow and filled with Alchemist Fire. After hitting a target, the arrowhead explodes, dealing 1d6 fire damage to the target in addition to the bolt's damage. Then, the target must make a dexterity saving throw, DC16, or be set on fire by the blast. A creature set on fire this way takes 1d4 fire damage at the start of each of its turns until it uses a bonus action to douse the flames.
