Our fighter has a quiver (1 ammo) of the Arrows of Acheron and asked if he could notch two arrows in his bow, since the arrows never miss. Not wanting to say no, I wrote up a custom move.
Trick Bow Shot
When you notch two arrows in your bow, take aim and shoot at one or two targets within range, spend one ammo and roll+DEX. On a 10+, you have a clear shot. You may choose to either deal your damage -1d6 to two targets or deal your damage to one target +1d6. On a 7-9, you still hit, but choose 1.
– You have to move to get the shot placing you in danger as described by the GM.
– One of your arrows goes astray and hits an unintended target determined by the GM. Deal your damage -1d6 to both targets.
– Your bow is damaged. You’ll need to spend time repairing it before you can use it again.
If you use this move, your GM may ask you where you learned to shoot like that.
