The water wizard is a monster that wanders around the meadow north-east of Rimmington and just north of the White Knight Camp. The water wizard roams the area with his three elemental companions: air wizard, earth wizard, and fire wizard. When engaged in combat, the water wizard can cast Water Strike and Weaken. If the player attacks with any type of water 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.
