Ring of Nondetection

This ring fashioned of dragon bone twists and reforms reality and the perception of reality in a small field around someone, hiding them, for a time, from the prying eyes of others.
Has three charges from which the spell Nondetection can be cast, requiring no spell slots of material components. At dawn each day it regains 1d4 charges as it absorbs latent energy from the Ley fields around it.
