Shadow magic weaves a silvered sword into existence. The sword floats in the air and follows the command of the wielder. As a bonus action, or as part of the action used to cast the spell, you can make an attack with the sword. No attack roll is made for this sword. Instead make a roll using your spell attack modifier against the targets passive intelligence (8+proficiency+intelligence modifier). If the roll is higher than the passive score, the target suffers 4d8 psychic damage. In addition, when commanding the sword with a bonus action you can move it up to 20 feet. If the sword is further away than 30 feet from the caster at the end of the caster's turn, the sword disappears and the spell ends.

At Higher Levels: for every level above 4th this spell is cast at, add 1d8 to it's damage.
