While wearing this ring, you have resistance to cold damage. In addition, you and everything you wear and carry are unharmed by temperatures as low as −50 degrees Fahrenheit.

The ring has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: Burning Hands (1 charge),  Fireball (3 charges), or  Wall of Fire (4 charges).

The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the ring blackens, crumbles into cinders, and is destroyed
