Oceanic Haladie

Haladie are double-bladed polearms that rely on the user's dexterity to keep them in constant motion.

This elegant weapon is adorned with engravings depicting leaping dolphins and drifting jellyfish. You gain a +1 bonus to attack and damage rolls made with this magic weapon, and you ignore the normal penalties on ranged weapon attacks while using this weapon underwater. While holding the weapon in front of you with both hands, you have a swimming speed of 30 feet. Additionally, while you hold the weapon, you can use an action to cast the water breathing spell. Once this property is used, it can't be used again until the next dawn.

Special: Whirl. When you are wielding the haladie in two hands, you can use a bonus action to attempt to whirl the weapon. To whirl, make a DC 10 Dexterity check, adding your proficiency bonus if you are proficient with haladie. On a success, you gain a +1 bonus to your AC until the start of your next turn, the whirling blades acting as a barrier against attacks. On a result of 15 or higher, you gain a +2 bonus, instead. On a failure, you deal slashing damage to yourself equal to your proficiency bonus and gain no bonus to your AC from the whirl this turn.

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.

Two-Handed: This weapon requires two hands to use. This property is relevant only when you attack with the weapon, not when you simply hold it.
