DC 10 Xorn are three-armed, three-legged creatures from the Elemental Plane of Earth. Their diet consists entirely of metal and gemstones.

DC 15 A xorn glides through stone as if swimming through water and can sense the presence of nearby creatures in contact with the ground.

DC 20 Xorn aren’t naturally aggressive. A meal of gems or precious metals usually placates them.


Native to the Elemental Plane of Earth, the xorn is a tripodal creature with rocky skin. Its dominant feature is the toothy, gaping mouth atop its head. The mouth is surrounded by three clawed arms and three large eyes that allow it to see in all directions at once.
The xorn can travel through earth and rock as if moving through water. On the Plane of Earth, div sometimes employ xorn as surveyors, scouts, and spies.

Always Hungry. The xorn’s diet consists of gemstones and precious metals. On the Elemental Plane of Earth, gemstone deposits and rich veins of precious metals are plentiful. Xorn that find themselves on the Material Plane, where such meals are harder to find, are forced to subsist on non-precious metal and ore.

Xorn are not naturally aggressive. They prefer to beg, steal, or bargain for coins and gems rather than take them by force. However, a starving or angry xorn might resort to violence, biting metal armor or buckles right off a foe’s body.
