you have altered your weapon to be able to create a small detonation. after a long rest you can choose one ranged weapon and once per turn you can choose to shoot a detonator arrow changing it from a roll to hit to a save (8+to hit bonus). it has an area of a number of ft equal to 2x your pb and deals the damage they would normally take to all in the area. you can use this 3 times per short rest.
