Earth and Magma Elementals are level 5 creatures of Conflux town. They are recruited from the Altar of Earth, or (unupgraded) from an Elemental Conflux. Earth Elementals can also be summoned with the Summon Earth Elemental spell.

"Earth Elementals are forces of Earth Magic. They take no damage from Mind, Lightning Bolt, Chain Lightning, and Firestorm spells. They take double damage from Meteor Storm attacks. From a source deep beneath the world's surface, roam the Magma Elementals. Slightly stronger than their earthen counter-parts, Magma Elementals can also cast the spell Protection from Earth." ^{AB manual}

Special ability

+100% to basic damage to Air and Storm Elementals.

Bugs

Though Magma Elementals are level 5 units, the game considers them as level 3 (in creature level-based calculations and 'random monster 3' object in the map editor). (Fixed in HotA).
