Crossing Fades

Magical Music emanates from your body or instrument, you can decide whether the people in a 30ft radius gain a +10 movement, 1d6+arcana, or a +1 to their AC. It's an action to activate, you can start with whichever you want, and you can change the song (buff) on your turn with a bonus action. The song will continue to play for 20min and every time it was your turn those you consider allies will heal 1d6+arcana again. Also every time it's an ally's turn and they are in your radius they will heal again if they need it of course. 

At Higher Levels: When used at a spell slot of 4th or higher, movement rises by 5 and AC will rise 5th and higher by 1. Healing is kinda wack but hopefully not too complicated
