Mud Mephit

When the mephit dies, it explodes in a burst of sticky mud. Each Medium or smaller creature within 5 feet of it must succeed on a DC 11 Dexterity saving throw or be restrained until the end of the creature's next turn.

While the mephit remains motionless, it is indistinguishable from an ordinary mound of mud.

Melee Weapon Attack: +3 to hit, reach 5 ft., one creature. Hit: 4 (1d6 + 1) bludgeoning damage.

The mephit belches viscid mud onto one creature within 5 feet of it. If the target is Medium or smaller, it must succeed on a DC 11 Dexterity saving throw or be restrained for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
