Blades

Summon 3 phantasmal blades around you, used to attack and defend.
As a action you can target up to as many creatures as you have available blades within 60 feet of you. Make a Ranged Spell Attack for each blade, dealing 2d6 Force damage per blade on a successful hit.

As a bonus action, you can form the blades into a defensive position. Doing so grants you a +1 to your AC per blade, up to a maximum of 3, lasting until the start of your next turn.

At Higher Levels: When you cast this spell using a Spell Slot that is higher than 3rd Level, you summon an additional blade for ever level above 3rd, up to a maximum of 5.

With 5 blades summoned, you may target a point within 60 feet of you and expend all blades towards that point. Each creature within 30 feet of your targeted location must make a Dexterity saving throw or suffer 10d6 Thunder damage, half as much on a successful save.
