Andai's Ring

This was an elvish ring of significant power, it allowed the wearer to resist the presence of Great Demons--even a Balrog, and provides protection vs. all spells as if the wearer were 30 levels higher. Designed of mithril with an amethyst set, it is proposed that it was made by Celebrimbor in Hollin.

Andai's Ring is what it is called because Andai eventually ended up with the ring. How it came to him is a mystery, but perhaps he acquired it on one of his adventures.
