Ruidium Haladie

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

This magic weapon has a dull, rusty color or has veins of ruidium running through it. While this weapon is on your person, you gain the following benefits:

• You can breathe water.
• You gain a swimming speed equal to your walking speed.

Ruidium Strike: A creature you hit with this weapon takes an extra 2d6 psychic damage.

Ruidium Corruption: When you roll a 1 on an attack roll made with this weapon, you must make a DC 20 Charisma saving throw. On a failed save, you gain 1 level of exhaustion. If you are not already suffering from ruidium corruption, you become corrupted when you fail this save.

If Ruidium Is Destroyed: If the Apotheon is killed or redeemed, all the ruidium in Exandria is destroyed instantly, and a ruidium weapon becomes a +2 weapon.

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.
