Omni-talisman

The Omni-talisman is a runecrafting item that can be obtained from Wizard Elriss after showing her every other talisman in the game. It gives access to all runecrafting altars that require a talisman for access. It can be combined with a tiara or a Talisman staff. To obtain it, one needs to be able to access the Runecrafting Guild, which requires 50 Runecrafting as well as the completion of Rune Mysteries to enter.
