Swift Strike

As part of the action used to cast this spell, you must make a melee attack with a sheathed weapon against one creature within the spell’s range, otherwise the spell fails.  You must have access to the weapon in order to make the attack and the weapon must have the light property.  On a hit, the target suffers the attack’s normal effects and takes force damage equal to your spellcasting modifier.  After you cast this spell, you may choose to sheath the weapon you used.

At Higher Levels.  At 5 level, the melee attack deals an extra 1d8 force damage.  The damage increases by 1d8 at 11level and 17 level.
