Veofur's Unharmonious Discord

You begin to play a very disruptive song that all creatures within 20 feet of you can hear. Each creature within 20 feet of you must make a wisdom saving throw. On a failed save, the creature becomes deafened and take 1d8 thunder damage, on a success, the creature takes half damage. Each turn, you must use your action to continue the spell. In doing so, each creature takes damage scaling with the amount of turns you have spent playing. For example, the second action you take playing, the target makes another wisdom save, then takes 2d8 thunder damage. At 5 rounds, you add the stun effect to anyone that fails the wisdom save.

At higher levels, the range increases by 5ft per level after 3rd level.
