'Envoke Earth Elemental' is a powerful, archaic (notice the primitive spelling) spell for those studying the art of elemental summoning.  This spell will petition local earth elementals for support in your travellings and battles.  After the spellcaster speaks the magical phrase of petition, a willing earth elemental will rise from the ground, forming the surrounding rocks, compacted dirt and tough roots into a psychical body with which the spellcaster can interact.
