Wavecutter Handaxe

This axe has a single pearl set at the center of its blade. You gain a +1 bonus to attack and damage rolls made with this magic weapon. When you take the Attack action using this axe, you can forgo one of your attacks to swing the axe in front of you and speak its command word. When you do, the axe emits a crashing wave of magical water. The wave is 10 feet tall and extends from you in a 30-foot cone, after which it spreads out across the ground in all directions, extinguishing unprotected flames in the area within 30 feet of it before the water vanishes. Each creature within the cone must make a DC 15 Dexterity saving throw. On a failed save, a creature takes 4d8 bludgeoning damage and is knocked prone. On a successful save, a creature takes half as much damage and isn't knocked prone. This property can't be used again until the next dawn.

Light: A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.

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.
