Elenore's Phalanx

As you walk the blade across your fingers, four magical blades are conjured from each knuckle and float above and around your head. Any creature standing within 5 feet of you when you cast the spell, and any creature that starts its turn or moves within 5 feet of you for the duration of the spell must make a Dexterity saving throw. The target takes 1d8+your spellcasting ability modifier force damage on a failed save—half damage on a success and no further effect. On a failure of the Dexterity saving throw, the target must make a Strength saving throw. On a failed save, the target is thrown 10 feet away from you, and their walking speed is halved until the end of their turn. You can do this up to four times per spell casting unless upcasted using a spell slot greater than 2nd level.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you gain an additional blade for every slot level above 2nd.
