The elementals of chaos are intelligent creatures native to one of the four elemental planes. Each of these elementals pursues its own interests vigorously with little, if any, care for order on either its home plane or the Prime Material Plane.
All elementals of chaos are immune to poison, normal weapons, and 1st- and 2nd-level spells. They also can cast detect invisibility at will. Elementals of chaos cast spells at the 9th level of ability.
Erdeen
Erdeens—lumpy rock beings about 9 feet tall—have long veins of metal and ore running throughout their bodies. They originate from the Elemental Plane of Earth.
Combat: In battle, an erdeen moves with surprising grace. It attacks either by slamming its victim with its fists (1d12/1d12 points of damage) or by casting spells.
The elemental can cast each of the following spells three times per day: detect magic, dispel magic, and earthquake. In addition, an erdeen can cast transmute rock to mud at will. The creatures are immune to all earth-based attacks, yet vulnerable to air-based attacks, which inflict an additional 3 points of damage per die.
Habitat/Society: Characters rarely encounter the solitary erdeens outside their home plane. When in Mystara, the creatures spend much of their energy rearranging the earth and rock into bizarre and unstable configurations. The homes of these elementals constantly shift, topple, and become vacant, as the erdeens move on to new sites. Fascinated by the chaotic instability of earth, these elementals feel amazed that so many creatures view it as a stable element.
Erdeens have been known to trap adventurers underground and engage them in bizarre discussions about the nature of reality. Those who please the quixotic elementals may go free, though what will please an erdeen can be difficult to deduce.
Ecology: The body of an erdeen yields 1d4x1,000 gold pieces worth of precious ores and metals. These creatures consider the stodgy galeb duhr and hydrax enemies, hate hordes, and fear air-based creatures and air-based attacks in general.
