Ogrémoch

Prince of Elemental Evil • Lord of Earth • The Mountain That Walks


Ogrémoch, Prince of Elemental Evil and Lord of Earth
Ogrémoch is not merely an earth elemental. He is a planar ruler who regards stone, metal, crystal and buried wealth as possessions torn from his domain.

Ogrémoch, Prince of Elemental Evil and Lord of Earth

Ogrémoch is the Prince of Evil Earth: a colossal elemental sovereign whose body resembles a walking mountain of dark stone and crystal. He does not raid for wealth because he needs it. He believes everything buried beneath the ground already belongs to him, and every mine, vault and foundation is therefore an act of theft.

Behaviour

Ogrémoch is patient in the way mountains are patient. He does not need to chase every enemy. He blocks roads, collapses tunnels, buries exits and waits for hunger, thirst and fear to finish what his fists began.

Alignment: his evil is territorial and possessive. Mortals are thieves who cut into his body for ore, gemstones and stone. A mine, buried treasury or underground city can attract his attention even when its inhabitants have never heard his name.

If Violence Starts

Break the Ground

He destroys footing first: walls rise, floors split, mud traps form and crystal spikes turn movement into damage.

Crush the Immobile

Once enemies are prone, restrained or boxed in, he closes and uses his reach and enormous slam attacks.

Outlast the Party

Ogrémoch is difficult to move, poison or disable. He is content to make the battlefield progressively worse until the party runs out of safe ground.

Lair & Earth Nodes

Ogrémoch favours immense caverns filled with black crystal, fault lines and jagged stone. In an elemental earth node he can turn ground to grasping mud, force crystal spikes from the floor or send violent tremors through the entire chamber. His lair should feel like the dungeon itself has chosen a side.

Sources & Rules Notes

The 5e baseline comes from Princes of the Apocalypse. The 5.5e and Pathfinder 1e tabs are compatibility conversions for campaigns using those rules. The 3.5e tab preserves the established legacy site version in a cleaner format.
