Enchant ruby or topaz

The Enchant ruby tablet is an item that can be used by any player to enchant ruby jewellery. Players can create this item on either a teak demon lectern or a mahogany demon lectern as long as they have 1 cosmic rune, 5 fire runes, and 1 soft clay, and at least level 49 Magic.

This tablet can be made regardless of the player's current spell book. Using a Staff of fire or Lava battlestaff can reduce the costs of casting the spell.
