Envenomed Strike

Prerequisite – 5th level Rogue, Ranger

When you hit a creature with a weapon attack, you can expend one superiority die to attempt to poison the target with a lasting poison. You add the superiority die to the attack’s damage roll as poison damage, and the target must make a Constitution saving throw. On a failure, the target is poisoned until the end of your next turn, and takes poison damage equal to an additional roll of your superiority die at the beginning of its turn.
