An earth elemental plods forward like a walking hill, club-like arms of jagged stone swinging at its sides. Its head and body consist of dirt and stone, occasionally set with chunks of metal, gems, and bright minerals.
Earth elementals glide through rock and earth as though they were liquid. Earthbound creatures have much to fear from an earth elemental, since the elemental can pinpoint the precise location of any foe that stands on solid ground in its vicinity.
Earth Elemental
Primal Spirit of Soil and Stone
Primal spirits from the Elemental Plane of Earth merge with rocks and minerals to form earth elementals. These beings possess powerful limbs and coarse features, sometimes studded with ore, gems, crystals, colorful striations, or living plants. On the Material Plane, earth elementals often serve those who conjure them, or they appear in regions influenced by their home plane, such as crystalline nodes, energetic fault lines, or veins of magical ore. Earth elementals effortlessly move through stone and can bring ruin to whole structures with their mighty fists.
Earth elementals are typically made of more than dirt. While an elemental's composition doesn't change its statistics or have monetary value, it makes each elemental distinct. Roll on or choose a result from the Earth Elemental Compositions table to inspire an earth elemental's features.
The foundations of our homes, the strength of our weapons, the vaults of our greatest secrets—earth is nothing less than the grip of reality itself. It is the mightiest element. This cannot be denied.

Crude, headless humanoid statues with clublike hands and feet
Earth elementals resemble crude, headless humanoid statues, with clublike hands and feet. They cannot cross a body of water wider than their own height. Earth elementals take double damage when attacked by fire (including fire elementals). They do an additional 1d8 points of damage against creatures, vehicles, or structures which rest on the ground.

Crude, headless humanoid statues with clublike hands and feet
Earth Elementals are creatures from the Elemental Plane of Earth, though they may sometimes be found elsewhere. When encountered on the Prime Material Plane, usually as a result of summoning magic, they seem to be vaguely humanoid mounds of stone, earth, metal and crystal. Whilst they may have a discernible head and face, it is usually devoid of expression and they will not speak, their language being the rumblings of the earth.
What Earth Elementals lack in speed, they make up for in relentless determination and dedication. They pass through rock and earth without hindrance, as they do along the ground, but they cannot travel through the air nor in or over water unless they remain in contact with the earth.
