The Divine Blade Falchion, also known as the Blade of Light, is a divine weapon forged by the Divine Dragon, Naga, for mankind's protection against rogue dragons. As it was forged from one of her very own fangs, only those with her blood are able to wield it properly; those without her blessings will find it no more effective than a pretty paperweight.
The divinity coursing through the blade will see it maintain its edge for thousands of years before its blessing even need to be considered for renewal. Keeping the blade on your person fills you with the power to slay dragons: damage you inflict on dragons is tripled. Focusing your might into a powerful attack will see you always being capable of fully slaying a dragon, no matter how powerful they once were.
During combat, you may call upon the blessings of the blade to recover from non-grievious wounds. Outside of combat and with a degree of focus, calling upon Naga's blessings can grant you a full recovery from anything short of death itself.
