How do you get an enchanters stone in dragonfable?

In Dragesvard you must ask to train the Dragonslayer's armor (talk to Galanoth), you will then go through a quest with the enchanters stone as the reward IF you get the required dice roll amount or more. (You can increase you chances by using Ice Dragon Scales found in Galanoth's Random quests and using them to increase the roll.)
