Basic Arrow of Piercing

Special arrow: Usefully against targets that stand in a line.

Range: 18 m / 60 feet

If succeed on the attack role, the arrow will fly through the target in a straight line for 15 feet damaging any creature (to maximum of 3 creatures). On hit, the first target will take [roll]1d8[/roll]. The creature behind will take 1/2 the initial damage rounded down. The final creature will take 1/4 the initial damage rounded down. Once fired, the arrow is consumed regardless of hit or miss. 

Note: Because of the strain from the special arrows that are put on bows, special arrows can only be used to the same number of the characters level once every long rest. (I.e. level 4 character can use 4 different special arrows once every long rest).
