From D&D Wiki
|Casting time:||1 bonus action|
|Duration:||Concentration, up to 1 minute|
You touch a nonmagical ranged weapon that uses ammunition, infusing it with nature's power. For the duration, when you attack with the weapon using nonmagical ammunition and hit your favored enemy, the target must make a Constitution saving throw. It takes an extra 5d6 piercing damage on a failed save, or half as much damage on a successful one.
