Fire storms are an elemental node in the Runespan that allows players to draw air runes and fire runes from it. They are found on middle and upper floors. It requires level 27 Runecrafting and gives experience in cycles of 22.8 experience if an air rune is siphoned and 41.7 experience if a fire rune is siphoned, though occasionally will also give 2 experience when a failed siphon is performed.
Although the requirement for Fire storms is 27 Runecrafting, they are only found on the middle and upper floors of the Runespan, thus making the requirement 33.
Unlike creatures, players do not receive any rune essence when a node is depleted of its energy.
