Create Weapon

You touch a nearby surface of non-magical metal, wood or stone at least 2 cubic feet in volume and transmute it into a melee weapon (your choice). While holding the weapon, you can cast this spell again to transmute it into a different type of melee weapon. The weapon returns to its previous shape when the spell ends.

The weapon becomes +1 at 5th level, +2 at 11th level, and +3 at 17th level.
