Vellum’s Vanquisher

You summon a weapon of your choice (such as a bow, or a sword) out of pure energy from the astral plane. As a bonus action you may change the form of your weapon. 

When the weapon appears, you make a melee spell attack against a target of your choice within the spells range (5 ft for a melee weapon or 120 ft for a ranged weapon). On a hit, the target takes 12d10 force damage, on each of your turns you can take an action to make an attack with the weapon. The spell ends if you use your action to do anything else.
