Electrostatic Fog

For the duration, magical fog spreads from a point within range and fills a 15-foot-radius Sphere, the fog arcs with lightning within the sphere. Darkvision can see through it, but at dim light and nonmagical light can’t illuminate it.

When a creature moves into the spell’s area for the first time on a turn or starts its turn there, that creature must succeed on a Dexterity saving throw or take 1d6 Lightning damage

If any of this spell’s area overlaps with an area of Bright Light or Dim Light created by a spell of level 2 or lower, that other spell is dispelled.
