Scarlet Dawn

Crimson light shines down in a 20-foot-radius, 60-foot-high Cylinder centered on a point within range. Each creature in that area that isn’t a Construct or Undead must make a Constitution saving throw, taking 4d10 Necrotic damage on a failed save or half as much damage on a successful one. Constructs and Undead in the area regain 4d10 Hit Points.

If any of this spell’s area overlaps with an area of Darkness created by a spell of level 3 or lower, that other spell is dispelled.

Using a Higher-Level Spell Slot. The damage increases by 1d10 and the level of spell that can be dispelled increases by 1 for each spell slot level above 3.
