The fire rune is one of the four basic elemental runes. Fire runes can be created from Rune essence or Pure essence through the Runecrafting skill, procured from drops by killing monsters, bought from other players, or picked up from spawns on the ground. Fire giants are among the monsters that drop fire runes often and in large quantities. Fire runes can be created using the Runecrafting skill at level 14 at the Fire altar in Al Kharid, which gives 7 experience per essence used.
Runecrafting fire runes is one of the fastest ways to achieve 44 Runecrafting for natures, through the use of dueling rings. Players can teleport to Castle Wars to bank and teleport to the Al-karid Duel Arena entrance, which is close to the fire atlar. This method uses two charges per trip, allowing four trips per dueling ring. From 14 to 44 runecrafting, one can expect to use over 100 dueling rings. Players can complete the Abyss miniquest to unlock a small pouch to increase carrying capacity by 2 essences. At 25 runecrafting, medium pouches can be used, allowing a total of 7 additional essences per trip.
