Drake Stone's Ring virtually resembles a silver skull with diamond eyes, but it has a complex and detailed design in the reminiscent manner with that of tribal masks.
This ring was, presumably, given to Drake's unnamed master and later to the boy himself before he left for an unknown reason or reasons when he was 15 years old. It is also likely that the ring was made by Drake's master. The ring eventually became a conduit for his magical powers as well as his own accessory, until Maxim Horvath stole it after using the Parasite Spell so he can both strengthen his magic and modify his cane. And also to free the legendary witch Abigail Williams from the Grimhold as one step further to release a far more greater evil from the past, Morgana le Fay.
Powers and Abilities
Drake's Ring's power appeared to be same with the other magic rings. The diamond eyes on the ring's skull-like mask feature glows with a purple aura whenever it is being used for conjuring spells and illusions.
