Black Moon

The user creates a black hole overhead, expanding the range of its absorption over a location you specify within range. Until the spell ends, a 30-foot-radius, 40-foot-high cylinder of pure darkness obscures everything there. When the cylinder appears, each creature in it must make a Constitution saving throw, taking 4d10 necrotic damage on a failed save, or half as much damage on a successful one. A creature must also make this saving throw whenever it ends its turn in the cylinder. A creature with darkvision can’t see through this darkness, and only a magical light spell of lvl 5 or higher can illuminate it.

If you’re within 60 feet of the cylinder, you can move it up to 60 feet as a bonus action on your turn.
