Barbarian Axe Handle

This decrative rod made if walnut wood appears to be the remnant of a weapon broken long ago. While ancient looking, it feels sturdy to the touch. Runes of a long forgotten language are carved down the length of the handle spelling out the words, "Honor, Glory, Victory"; the Axe's command phrase. It was turned in to a magical rod by a wizard who managed to use the magics of transfiguration to make it retake its original form, though not made from metal but using the mental acuity of its wielder but not without a price.   

Speaking the Axe's command phrase as a bonus action activates the weapon, causing a shimmering blue double axe head to appear. The weapon can be used as a battleaxe, or it can be used to cast Spiritual Weapon. When used in this manner, the handle remains in the caster's possession and is used to command the spiritual axe.

Activating the axe consumes at least one charge, of which the Axe has a single charge that is regained daily at dawn.  

Using that charge and by saying its command phrase turns the rod in to a mystical battleaxe. It stays as a battleaxe as long as it deals damage in each round of combat. It has the regular profile of a battleaxe  the weapon 1d10 damage. The bearer may choose which of its mental skills it uses to create the axe shape (Int, Wis or Cha) and applies this plus their proficiency for  hit and damage modifiers.  

Upon using the charge on this weapon, you have disadvantage every time and in every way you could use the same skill that is used to create the blade (Int, Wis or Cha) for one hour.  This includes saving throws, attacks, spell casting or any abilities which use this skill (i.e. Using Cha will give you disadvantage on charisma saving throws, spell casting that uses charisma and persuasion, deception checks etc)
