Whirlpool Dart

This dart feels cold and hefty in the hand, but flies effortlessly when thrown. As an action, you can throw this dart at a point within 20 feet of you and speak its command word to cause it to create a wild, spiraling whirlpool in a 15-foot-radius, 10-foot-high cylinder centered on that point. Each creature in the area excluding you must make a DC 13 Strength saving throw. On a failed save, a creature takes 4d4 bludgeoning damage and is pulled up to 15 feet toward the center of the cylinder. On a successful save, a creature takes half as much damage and isn't pulled. In addition, unsecured objects that are completely within the cylinder are automatically pulled 15 feet toward the center by this effect, and all nonmagical flames within the cylinder are extinguished. The dart's property can't be used again until the next dawn. In the meantime, the dart can still be used as a magic weapon.

Finesse: When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.

Thrown: If a weapon has the Thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the Finesse property.

Range: A weapon that can be used to make a ranged attack has a range shown in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second indicates the weapon's maximum range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can't attack a target beyond the weapon's long range.
