Eldritch Convergence

You converge chaotic energies around yourself, distorting reality in a 60-foot radius centered on you. For the duration, any creature within this area must make a Wisdom saving throw at the start of its turn. On a failed save, the creature is disoriented, taking 5d6 psychic damage and having disadvantage on attack rolls and saving throws. On a successful save, the creature takes half damage and isn’t disoriented. Additionally, the area is filled with unsettling, cosmic sounds and sights, making it difficult for creatures to concentrate. Roll a d6 at the start of each of your turns; on a 1-2, you take 3d6 psychic damage.
