4th-level / Tiger Claw
As your foe dies on your blade, you twist and turn your weapon to send blood spraying across the battlefield. If you reduce an opponent to 0 hit points, you can initiate this maneuver. Your weapon rips into your foe as they drop, and forcing all your enemies within a 30-foot radius to succeed on a Wisdom saving throw or be frightened by you for 1 minute. Frightened creatures can repeat this saving throw at the end of their turn. For each foe you hit during your turn prior to initiating this maneuver, the save DC increases by 1.
