It's frustratingly difficult to find more detailed information about this book that would prove its match to the question. Wikipedia and Goodreads puts it at a 1977 publish date - exactly 45 years ago. A blurb:
The Ring, The Jewel, The Bone:
These are the Relics. The Mysteries of the Shrine, known only to the priestess. Only to Oaive. Yet he knows of them--the wolflike stranger from beyond the mists. And when he profanes them, there begins a game of cold sorceries and burning shadows to be played through all eternity...one way or another.
