This magic blade occupies one of the casters free hand's after casting, and lasts until the spell ends. It counts as a Dagger, and has all the weapon properties of a Dagger. It deals 1d4 + the casters spellcasting ability modifier + the spells level in Force Damage on a hit. If the blade leaves the caster's possession, they throw it, or they drop the blade. It is not dispelled, other creature's then the caster may use the blade for its duration.

Additionally as a Bonus Action on the caster's turn. If the caster is within 60 feet of a blade they created, they can cause one blade (of there choice, if multiples exist) to pulse out energy in a wave around it. All creatures within 5 feet of the blades location must succeed on a Dexterity saving throw or take deals 1d4 + the casters spellcasting ability modifier + the spells level in Force Damage. If a creature is holding the blade, the creature holding it (at the casters discretion) ether automatically succeeds or fails the saving throw.
