Enchanted gem

The Enchanted gem is an item used in the Slayer skill. They are sold by all Slayer masters. This item can be obtained for free the first time, and for 1 coin each after that if you have lost it. These allow you to contact your slayer master, ask for tips, ask who the master is and where they are located, and most importantly see how many monsters you still have to left to kill for your slayer assignment. An alternative to the gem is a worn bracelet of combat, which will update the player every 10 kills.
