Chaos rune

The chaos rune is used for bolt spells, including Wind Bolt, Water Bolt, Earth Bolt, and Fire Bolt. It is also used for Crumble Undead, which is the highest level spell for a chaos rune in the free-to-play version of RuneScape. Additionally, it used for some members spells such as the various Ancient Magicks spells. Respawning Chaos Runes can be found in the far room of the Dark Knight's Fortress in the wilderness or near the Moss Giants in the level 40 wilderness. They take 70 seconds to respawn.

Chaos runes can also be made through the Runecrafting skill at the Chaos altar at level 9 wilderness. You must have a Chaos talisman or a Chaos tiara to enter. Upon entering, you will find yourself in a complicated maze which you will have to find your way through in order to craft your runes. Another way of entering is through the statue of Saradomin north-west of Varrock and through the Tunnel of Chaos to the portal which requires the talisman or tiara. This is only accessible during or after completing the What Lies Below quest. A player gets 8.5 experience per chaos rune crafted.
