Amulet

The Amulet is a neck item in Club Penguin. Member Ninjas could purchase this item from the Martial Artworks catalog for 200 coins. However, it was available for Non-Members in November 2011.

It is the key item to enter the Fire Dojo and the Water Dojo, and it allows playing Card-Jitsu Fire and Card-Jitsu Water. When becoming a Fire Ninja, the Fire Gem is added on to the Amulet, and when becoming a Water Ninja,the Water Gem is added to the amulet.

Description
The description from Martial Artworks:
 * "Behold the Amulet. A symbol of power and skill, and a key to mastering the elements. Continue your journey by opening the hidden doors in this room. The next Dojo awaits."

Trivia

 * There used to be a sign in the Dojo Courtyard saying "HELP GOLDSMITHS BUILD AMULETS", with blueprints for the amulets and an actual amulet. It was taken down after Card-Jitsu Fire was released.
 * There is an amulet pattern on the floor of the Ninja Hideout.
 * As of now, the Fire Gem and Water Gem are currently the only gems available.
 * Many thought that the Amulet would be unavailable for Non-Members after December 6th, but that has not happened.
 * If you have a gem, the Amulet on the ground of the Ninja Hideout glows according to your gem(s).
 * The Amulet became a Non-Member item during the Card-Jitsu Party 2011 and has remained a Non-Member item ever since.
 * In the Ninja Hideout, there is an Amulet placed on the ground, which reminds Duenos inscription- a known old latin text.
 * There was a glitch on French servers before the Amulet was released where you could see the Amulet in the Martial Artworks catalog. If you clicked to buy it, it would have a loading screen that lasts forever.
 * The center gem, which is rumored as the shadow gem, is already added to your amulet because you mastered Card-Jitsu, not Card-Jitsu Shadow.
