These arrows have normal fletching and shafts, but the head is made of a small glass vial. The vial is designed to break upon impact, and it contains a dose of one of the following items: Acid, Alchemist's Fire, or Holy Water. Upon a successful hit, the vial breaks and affects the target accordingly. If the attack misses, roll 1d8 and determine the square that the arrow hit as per the rules on throwing a splash weapon.
