Blade Waltz

You distort space, causing your melee weapon attacks to travel to your target as if right next to you. As an action, you touch one melee weapon linking it to the ethereal plane. As part of the attack action with the chosen weapon, the wielder can target a creature within 90 feet that they can see and make an attack with the weapon as normal, adding bonuses to hit and damage, (this effect is subject to the extra attack feature) dealing an additional 3d6 force damage on a hit.

Attacks made with weapons affected by this spell can also hit targets on the ethereal plane.

At higher levels. When you cast this spell with a 6th or 7th level spell slot, the damage increases by 1d6, and the range extends to 120 feet. When you cast this spell with an 8th or 9th level spell slot, you may affect two weapons at a time with this spell, and the damage increases by 2d6.
