You conjure a blade of force in your free hand. The blade is similar in size and shape to a sword. It appears engulfed in a white and blue flame. If you let go of the blade, it disappears, but you can conjure the blade again as a bonus action.
You are proficient with the blade and can make melee weapon attacks with it. It is a magic weapon with the light and finesse properties, and it deals 1d10 slashing damage on a hit.
You may cast any spell into the blade that targets one creature and doesn't make a ranged attack roll. You expend the spell slot for that spell, and the spell is held in the blade until either it is released or the blade disappears; only one spell can be held in the blade at a time. If you hit a creature with the blade, the held spell is released: in addition to the normal damage, the target is affected as though you had cast the held spell on it.
