Catalytic rune

Catalytic runes are generic non-elemental runes. Each rune can act as one of the non-elemental runes (mind, body, chaos, death, blood, nature, cosmic, law, soul and astral). They are only currently used in the Fist of Guthix, Barbarian Assault, and the Stealing Creation minigames.

At the beginning of every Fist of Guthix game, each player receives 300 catalytic runes along with 1,000 elemental runes. They can only be used to cast combat spells within the minigame.

In Stealing Creation the player collects clay and brings it to the creation kiln to create catalytic runes.

Catalytic runes within Barbarian Assault
Due to a recent update, Barbarian Assault now uses elemental and catalytic runes, instead of the standard ones. This is because players often found glitches that could let them escape Barbarian Assault with the runes.
