Ephemeral Weapon

You conjure a melee weapon composed of magical material to your hand. As part of the action made to cast this spell, you make a single melee attack against an enemy within 5ft. of you. Use your spellcasting ability modifier for the attack and damage rolls. The damage die of the weapon is 1d10, and it deals force damage. The weapon disappears after the attack has been made.

When you reach 5th level, you may make one additional attack with this weapon when attacking on your turn. You gain a third attack at 11th level, and a fourth at 17th level.
