You create a shimmering veil of shifting black mist that muffles light and sound. The area in a 20-foot-radius sphere centered on a point you choose within range becomes lightly obscured in dim light.
You and up to three creatures of your choice inside the veil become invisible while in the area and have resistance to radiant damage.
However, creatures who enter the veil for the first time on a turn or start their turn there must make a Wisdom saving throw or become frightened of what lurks within the shadows until the end of their next turn.
When the spell ends, the shadows burst outward — all creatures in the area must make a Constitution saving throw or take 3d8 necrotic damage (half on a success)
