The earth wizard is a monster that wanders around the meadow north-east of Rimmington. The earth wizard roams the area with his three elemental companions: air wizard, water wizard, and fire wizard. When engaged in combat, the earth wizard can cast Earth Strike and Weaken. If the player attacks with any type of earth spell, the wizard will say "Gratias tibi ago", a Latin idiom meaning "Thank you", and then heal himself.
Healing one of the elemental wizards (air wizard, water wizard, earth wizard, or fire wizard) with the correct elemental spell is one of the Falador Tasks.
