Starmetal Solar Axe (Dual Battleaxes)

This heavy metal magical weapon is forged using iron from the stars. While you're attuned to this weapon, you can call upon its latent stellar energy to catalyze change within the metal and create endothermic and exothermic reactions. The weapon can be fused into a greataxe or fissioned into two separated battleaxes. The weapon has the following properties based on its current state:

Fissioned State. While wielding the two fissioned battleaxes, you gain a +1 bonus to attack and damage rolls made with them. The weapons are bitter cold to the touch and deal an extra 1d6 cold damage to any target they hit. The axes orbit you slowly while they aren't being held or stowed. You can retrieve a floating battleaxe as if it were sheathed. In addition, when you take the Attack action, you can use a bonus action to make one melee weapon attack with an orbiting battleaxe against a creature you can see within 20 feet of you.

State Change. This weapon can change between two states using the following properties:

Fusion. While holding both battleaxes, you can use a bonus action to speak the weapon's other command word to recombine the two battleaxes into its fused state. When you do, the sudden generation of heat creates a wave of fire around you, forcing creatures within 30 feet of you to make a DC 17 Dexterity saving throw. A creature takes 3d6 fire damage on a failed save, or half as much fire damage on a successful one. This property can't be used again for 12 hours.

Proficiency with a Battleaxe allows you to add your proficiency bonus to the attack roll for any attack you make with it.
