Gofannon amulet

The Gofannon amulet is an amulet found along with the second high-quality ore during What's Mine is Yours. On completion of the quest, the amulet gives 500 bonus experience to players while training Mining and/or Smithing, in the same way that Clan Rings or Skilling Pendants do. However, this amount can be significantly increased by completing the tasks Doric and Boric assign to the player after the quest. These extra tasks can only be done by members. The amulet gives a 2x experience boost for as long as it holds charges. Each charge equates to 1 experience point.

The following table shows the amount of bonus experience added to the amulet after completing specific tasks.

Trivia

 * In mythology, Gofannon was a Celtic deity, portrayed in Middle Welsh literature as a great smith. The name Gofannon itself means 'smith' in some Celtic tongues, including Old Irish, Middle Welsh and Gallic.
 * The amulet resembles a miniature anvil, highlighting its role in the Smithing skill.
 * When the amulet was first released, free players could not gain bonus experience from it, and could only check the charges inside. This was fixed a short time later.
