Sword Beam

You project a solid beam of force from your weapon. As part of the action used to cast this spell, you must make a melee (turned into ranged) attack with a bladed weapon against one creature within the spell’s range, otherwise the spell fails. On a hit, the target takes 1d8 force damage plus your weapons damage modifier. 

This spell’s damage increases when you reach higher levels. At 5th, 11th, and 17th level, the attack deals an extra 1d8 force damage to the target.
