Chorus of Awe

You snap your fingers, and the sky becomes bright with a rift. Directly above you, a heavenly choir sounds and begins to sing an awful song sure to empower your allies. Whenever an ally is within 20 feet of you and makes an Attack Roll, Saving Throw, or Strength (Athletics) check, the target adds your proficiency bonus to their rolls. If a creature cannot hear, feel, and see the chorus, they are unaffected. You must use your action to continue the concentration on this spell.
