In-game description
"Ring of Earth Elemental Command If the songs of bards are correct, all one must do is wear this ring and they will gain the ability to control earth elementals at will. Of course earth elementals are not easily controlled and care must be taken when commanding one. An angry earth elemental can make short work of an inept adventurer."
