Whirling Strike

Ryoko's Guide to the Yokai Realms
Loot Tavern

In a blitzing vortex of aggression, you strike at all those around you in a sinuous assault. Each creature within your reach must make a Dexterity saving throw. A creature takes damage of your weapon’s type equalling a number of d6s equal to your proficiency bonus on a failure, or half as much damage on a success. Success or failure, the creature can’t make opportunity attacks against you until the end of this turn.
