Blade Storm

You imbue your blades with ethereal magic.

Touch up to 4 daggers. Each dagger touched in this way is imbued with ethereal energy and float in front of the caster. As an action or bonus action, the caster may fire on ethereal dagger (1d4+1d6). After firing a dagger, it looses its ethereal property and stays at the impact site. If a creature is dropped to zero hit points after a dagger hits it in this way, all daggers are refreshed. As an action, the caster can also fire all daggers at once, but does not replenish the ethereal property on a creature's drop to zero hit points.

At higher levels: Each spell slot above level 2 increases the amount of daggers that can be imbued by 1.
