Greater Earth Elemental (Basic Lore)

Greater Earth Elemental (CR 18)
Neutral - Huge - Outsider (Elemental, Earth)
Whether a patch of odd crystals in a ruined corridor, a pool of oddly turbulent water in a forest grove, a roaring breeze even indoors, or a cozy campfire with malevolent eyes, elementals can be found almost anywhere. Many elementals are spontaneous manifestations, creatures of elemental nature that have arisen from either natural or unnatural circumstance. Other elementals are deliberately made things, summoned or created by those with malevolent purpose, set as immortal guardians or stalkers of the world. Elementals may be fairly common or quite rare, depending upon the setting. In all cases, elementals provide plenty of challenges and fun for those heroic enough to face them. An earth elemental looks like a pile of rocks and dirt, perhaps with the odd plant rooting in it. When dormant, earth elementals are very hard to spot, since they might be resting ten feet underground, and even if they are on the surface, one pile of rocks and soil looks much like any other. But when they manifest their raging essence, earth elementals are unmistakable, masses of rock and soil given terrible vitality and a fervent wish to destroy whatever has drawn their anger. Earth elementals change shape less than other sorts of elementals, but their form is certainly not fixed. They can look like anything, as long as that thing is made of stone and soil.
