Monster of the Month: Storm Elemental

Each month, we’ll give you a new monster to use in your 5e game. This month, we give you the Storm Elemental. You can download the description and stat block of the ice elemental here.

Storm Elementals

Storm elementals are the manifestations of thunderstorms, monsoons, and tempests. Their bodies are made of thick, dark grey clouds, rippling with bolts of electricity. The coming of a storm elemental is heralded by flashes of lightning and the peals of thunder.

Storm elementals are usually encountered on the Material Plane in areas where there is already heavy precipitation or bad weather, such as storm- battered seas or tropical rainforests. They are encountered more frequently during certain times of the year, such as summer afternoons or, in certain climates, the yearly rainy season.

Stormbringer

A storm elemental affects the weather patterns of whatever area that it is in, bringing rains and wind. This can create dangerous conditions, but at least the storm elemental can’t sneak up on anyone.

Thunder and Lightning

A creature facing a storm elemental has to be wary of two dangers. Just like a thunderstorm, each of a storm elemental’s lightning strikes is followed by a wave of booming thunder.

The Other Elements

Most adventurers know about the four most common types of elementals: air, earth, fire, and water. In some worlds, however, there are more than four elements. Storm is one of these other elements, together with other things such as ice, wood, metal, or even time.

Some multiverses might have a separate Plane of Storms from which storm elementals come. In others, a demiplane of storm exits where the Planes of Air and Water touch. If you introduce storm elementals into your game, consider their origins relative to the
four common elementals.
