Call to Arms

 You inspire unrelenting power and energy in a creature of your choice. One willing creature that you touch is called to fight, and until the spell ends, they are immune to being frightened or charmed, and gain advantage on their next attack roll.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, you can target one additional creature for each slot level above 3rd. All willing creatures must be within 5 ft of you.
