The Fire Infinity top is a standard Infinity top that has been coloured with a Rune guardian. To do this, players must use their infinity top on the Fire altar with their rune guardian either following them or in their inventory. Once coloured, the top is untradeable. Colouring Infinity robes is cosmetic and will not change their stat bonuses. In order to remove the colouring, players may use the robes on their rune guardian.
