Smoke Mephit

When the mephit dies, it leaves behind a cloud of smoke that fills a 5-foot-radius sphere centered on its space. The sphere is heavily obscured. Wind disperses the cloud, which otherwise lasts for 1 minute.

The mephit can innately cast dancing lights, requiring no material components. Its innate spellcasting ability is Charisma.

At will: dancing lights

Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 4 (1d4 + 2) slashing damage.

The mephit exhales a 15-foot cone of smoldering ash. Each creature in that area must succeed on a DC 10 Dexterity saving throw or be blinded until the end of the mephit's next turn.
