Smoke Paraelemental (5e Creature)
From D&D Wiki
Large elemental, neutral
Damage Resistances fire, lightning, thunder; bludgeoning, piercing, and slashing from nonmagical attacks
Smoke Form. The elemental can enter a hostile creature's space and stop there. The first time it enters a creature's space on a turn, or a creature begins its turn within the elemental's space, that creature takes 5 (1d10) poison damage (unless that creature is not required to breathe). As long as a creature occupies the same space as the elemental, it is blinded. Upon exiting the elemental's space, the creature must succeed on a DC 13 Constitution saving throw or remain blinded. The target can repeat the saving throw at the end of each of its turns (as long as it is not within the elemental), ending the blindness on itself on a success. The elemental's space is considered heavily obscured to all creatures other than the elemental itself. It can move through a space as narrow as 1 inch wide without squeezing.
Multiattack. The elemental makes two slam attacks.
Slam. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.
Asphyxiate (Recharge 4-6) Each creature in the elemental's space must make a DC 15 Strength saving throw. On a failed save, the target takes 13 (2d8 + 4) poison damage unless it doesn't need to breathe. If it is Large or smaller, it is also grappled (escape DC 14). Until this grapple ends, the target is restrained and unable to breathe. If the saving throw is successful, the target is pushed out of the elemental's space.
As gusts of chaotic wind meet primal cinders on the outskirts of the Elemental Planes of Air and Fire, smoke paraelementals are given life. A twisting figure of thick, noxious fumes; a smoke paraelemental clings to areas ravaged by fire damage to delight in the darkness and gleefully inhale dense, lethal smog.
