Crystal Weapon

You conjure a magical weapon from the elemental plane of earth. As an action you summon a melee weapon of elemental energy, this weapon appears in the form of any melee weapon of your choice, attacks and damage with this weapon use your spell-casting ability, and the weapon counts as a +1 magical and you count as proficient with this weapon. If the weapon is disarmed or dropped it can be recalled with a bonus action.

When this spell is cast using higher level spell slots the damage magical bonus increases to +2 to attack and damage rolls if cast as a level 5th spell, and +3 to attack and damage if cast as a 7th level spell.
