Best Defense is a Strong Offense

You are trained to strike first at a creature that is attacking you, potentially making the creature miss.

Prerequisite: The Lord's Alliance faction membership, Character level 6.

Benefit: When you are about to be attacked by a creature with a melee weapon attack but before the outcome is determined, you can use your reaction to make a single melee weapon attack against that creature. If your attack hits, you impose disadvantage to the creature's attack.

Once you use this feature, you cannot use it again until you finish a long rest.
