Bone Blade

You conjure a Weapon from the air which takes the form of a sharpened Bone. This magic sword lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d8 slashing damage on a hit. If you drop the weapon or throw it, it dissipates at the end of the turn. Thereafter, while the spell persists, you can use a bonus action to cause the sword to reappear in your hand.
