Strike Bow (5e Equipment)
From D&D Wiki
Weapon (any bow), uncommon
A normal looking wooden bow, with a thick string that seems to hum even when still.
Arrows fired from this bow strike with far more force than they should. On a successful hit, the target is knocked backwards if they are Medium or smaller. Creatures that are Small or Medium will be knocked backwards 10 feet. Creatures that are Tiny or smaller will be knocked backwards 20 feet. If the target hits a solid obstacle, they stop and take 1d6 bludgeoning damage. If they are driven into another creature, both creatures will take 1d6 bludgeoning damage.
