You are practiced in the art hitting multiple targets at once in melee, granting you the following benefits:

• As an action, you can make a Whirling Strike, allowing you to attempt to hit as many creatures in your weapons range that is equal to your total attacks per action, that are not obscured by any cover. They must make a DC 10 + your strength modifier + proficiency dexterity saving throw. For every hit, roll 1d4 and subtract the number from the DC for the next target.
• When you hit a creature with this ability, they take an extra amount of the weapons damage type equal to your level.
