WARM BOOTS OF FROBOZZ

The one who worm the Warm Boots of Frobozz would be impervious to neuritis, neuralgia, and muscular aches and pains.

These were gifted to Mirakles of the Elastic Tendon by the Control Character in the tenth century, shortly before the end of the First Age of Magic (966 GUE).
