Smoke Elemental

Smoke elementals are native to the Para-elemental Plane of Ash, where the Plane of Air and Plane of Fire collide. The ash that makes up a smoke elemental ranges from faint motes to fiery zephyrs. Its component mixture can cause breathing problems when inhaled, and it causes burning in the eyes when it attacks. Ironically, a strong wind can damage a smoke elemental, diluting its ashy substance.
Smoke elementals rarely travel to other planes, unless they are summoned by magic or travel through a portal. They might appear, however, in places where someone from a mortal world opens a portal to the Elemental Plane of Fire to immolate, to power a forge, or to drive arcane machinery. Those fighting large conflagrations all too often find themselves contending with confused and hostile smoke elementals that get pulled into their world.

Between the Elemental Planes of Air, Earth, Fire, and Water, which exemplify the elements that make up the multiverse, lie the Para-elemental Planes: regions where Elemental Planes collide and their elements mingle. These Para-elemental Planes are the Plane of Ash, the Plane of Ice, the Plane of Magma, and the Plane of Ooze. These planes are home to the para-elementals: ice elementals, magma elementals, mud elementals, and smoke elementals.
