Elemental runes are the most basic type of rune and represent each of the four ancient elements: air, water, earth, and fire. At least one of them is used to cast every spell in the Magicspellbook.
They can be obtained as drops from numerous monsters such as dark wizards, chaos druids, hobgoblins, or pirates. Players may also find them at various item spawn points around RuneScape Classic, although they tend to be in small quantities and can take over 30 seconds to respawn. Large quantities are sold at Magic shops starting at 4 coins each.
