Air Strikes

You touch a willing humanoid within range. The humanoids arms are surrounded by spirals of air that extend to cover their weapons, giving the humanoid an extra 5 ft. of reach on their melee attacks. This effect lasts for 1 minute and requires concentration.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target one additional humanoid for each slot level above 2nd.
