Conductive. If the elemental takes lightning damage, each creature sharing its space takes the same amount of lightning damage.

Fluid Form. The elemental can enter and end its turn in other creatures’ spaces and move through a space as narrow as 1 inch wide without squeezing.

Freeze. If the elemental takes cold damage, its speed is reduced by 15 feet until the end of its next turn.

Elemental Nature. An elemental doesn’t require air, sustenance, or sleep.


Multiattack. The elemental makes two slam attacks.

Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage. 

Whelm. The elemental targets each Large or smaller creature in its space. Each target makes a DC 15 Strength saving throw . On a failure, the target is grappled (escape DC 15). Until this grapple ends, the target is restrained and unable to breathe air. The elemental can move at full speed while carrying grappled creatures inside its space. It can grapple one Large creature or up to four Medium or smaller creatures.


The water elemental uses Whelm to drown two or more creatures, beating them with slam attacks while they’re restrained in the elemental’s space. While on dry land, the elemental seeks cover from mobile ranged attackers. Elementals retreat only if ordered to do so.

Legends and Lore

With an Arcana or Religion check, characters can learn the following:

DC 10 Elementals are spirits of fire, earth, air, and water not native to this world. Spellcasters can summon elementals and bend them to their will. An uncontrolled elemental may turn on the creature that summoned it.

DC 15 Elementals are resistant to nonmagical weapons and immune to poison. Earth elementals are vulnerable to thunder. Fire elementals take damage from water. Water elementals are slowed by cold damage. 


Spellcasters and other powerful beings draw upon the animating life force of the pure elements—air, earth, fire, and water—to manifest elementals. Just as our world is home to birds, beasts, trees, and flowers, the elemental planes contain shapeless spirits of energy and instinct. These inchoate entities can be exploited with magic to create compliant servants and timeless guardians. 

Shaped for Service.  A conjurer of sufficient skill can shape an elemental as they please, not just as creatures, but also as weapons or objects of artifice. Elemental power can create stone soldiers, forges of living flame or ships carried on their own currents, and windmills turned by an endless breeze. Elemental servants might resemble large humanoids, primal beasts, or divine avatars. The only limit is the summoner's imagination and their will to control the elemental.

Perilous Conjuration. A wild spirit of elemental force has little sense of self, content to be one with the element with which it shares an affinity. Should an elemental break free from control, it becomes an animate mass of its native element, wreaking havoc without regard for its surroundings.
