The Eye of the Dragon is an essence gem which grants a large bonus to all three ability scores (Body, Mind, and Spirit). It also provides players with the Celestial Aura effect, which grants a 5% chance that when players are hit, a shockwave will be generated. It is only usable by followers of the Way of the Open Palm, with followers of the Way of the Closed Fist having a similar gem called The Eye of the Demon instead. The two gems are jointly the pinnacle of a series of similar gems, the next highest being the alignment-neutral Scintillating Gem of Power.
It can be found by Open Palm players in Dirge's Gem Repository (in the western portion of the Outer Courtyard).
In-game description: "The Eye of the Dragon is a gem of heroes and figures of legend. Tales claim that the gem is, indeed, the eye of a great Dragon of Heaven, long since burned from living memory. the gem gives its user the power of great warriors of the past, but it bestows the same obligations with which they lived: to be a great hero and champion of all people."
