Incredibly light, this pearlescent scimitar can bloom into a bladed fan. You gain a +1 bonus to attack and damage rolls with this weapon. It also gains the thrown property (range 30 ft / 90 ft.). When thrown no more than 30 ft. it comes back to your hand at the end of your turn.
While in your hand, you can cast the cantrip Gust at will by using this blade. In addition, you can use an action to throw this blade to a point you can see and cause it to spin quickly, creating a whirlwind. All creatures in a 20 ft. radius around the blade must succeed on a Strength saving throw (DC 15) or be pulled 20 ft. toward the blade and take 6d6+6 slashing damage. The blade then returns to your hand. You can use this ability once and you regain the ability to do so at dawn.
