Ellerie’s Aura of Song

You weave a melody of protective magic that resonates in a 20-foot aura around you. Choose a number of creatures within the aura, up to your Charisma modifier (minimum of one). Until the spell ends, the first attack roll made against each chosen creature on a turn is made with disadvantage while the creature remains within 20 ft of you, as the harmonious tones distort your foes’ aim.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can choose one additional creature for each slot level above 3rd.
