Choreography

With a gesture and a flourish, you unleash a burst of inspiration that fuels your allies' movements. For the duration, you and each creature you choose within range that can see or hear you gains a +10 bonus to its Dexterity (Acrobatics) and Charisma (Performance) checks until the spell ends. If you and one or more other creature affected by this spell rolls Initiative while affected by this spell, you can exchange the initiative order of any two or more affected creatures as you see fit, at which point the spell ends. 

At Higher Levels. When you cast this spell at higher levels, it gains several additional benefits. If you cast this spell using a spell slot of 4th level or higher, affected creatures also gain advantage on Initiative rolls they make if they are not surprised. When you cast this spell using a spell slot of 6th level or higher, opportunity attacks against your allies have disadvantage while the spell lasts.
