Enchanted gem

The Enchanted gem is an item used in the Slayer skill. They are sold by all Slayer Masters for one coin. These allow a player to contact the slayer master that has assigned them their current slayer assignment, where they can ask for tips, ask who the master is and where they are located, and most importantly see how many monsters they still have left to kill for their slayer assignment. An alternative to the gem is a worn Combat bracelet, which will update the player every 10 kills if it has 1 or more charges. The Enchanted gem is a component of the Commorb obtained from Sir Tiffy Cashien and also the Slayer ring. You cannot ask for a new Slayer task through the Gems, you have to go talk to the Slayer Master in person. The Enchanted gem has a right-click option to quickly check how many monsters are left for your assignment. Before that update, checking how many kills left would be interrupt by combat, so you had to wait until the monster was defeated before checking it.

Trivia

 * The Enchanted gem is referred to as a 'Slayer gem' when all the charges on a Ring of slaying are used. "The ring collapses into a Slayer gem, which you stow in your pack"
 * There is a bug where after a slayer task has been finished, asking for tips will send the player back to the beginning of the conversation
 * After While Guthix Sleeps has been completed it is still possible to contact Duradel by asking the master "Have you got any tips for me" after a task has been completed, if you have the correct requirements they will pass you over to Duradel.
 * Before the HD update, when contacting a slayer master via the gem, it would show the slayer master in a light blue oval instead of just a face.
