Cosmic Ooze

You launch a glob of radiant stellar slime at a creature within range.

Make a ranged spell attack against the target. On a hit, the target takes 1d8 radiant damage and glows with celestial residue until the start of your next turn. While glowing in this way, the target gains no benefit from being invisible.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8)
