Oreads

Oreads are humanoids with a strong connection to the earth. They are typically stocky and muscular, with stony or rocky skin that ranges in color from brown to gray. They are often associated with mountains, caves, and other subterranean environments.

Mechanics: Oreads gain the following ability boosts at character creation: +2 Strength, +2 Constitution, and -2 Charisma. They have a speed of 25 feet, darkvision, and the Earth Affinity heritage feat, which grants them resistance 5 to acid damage. They also have a unique ability called Earth Sense, which allows them to automatically sense any stone, earth, or metal within 60 feet of them. This ability can also be used to determine the depth and density of these materials.

In addition, Oreads have access to a number of feats and abilities that allow them to manipulate earth and stone. For example, the "Earthen Grasp" feat allows an Oread to create a hand of earth that can grapple an enemy or move objects, while the "Stone Call" spell creates an earthquake that can knock down enemies and create difficult terrain.
