This small, icy orb is cold to the touch, with snow flurrying around it. While it is on your person, you have immunity to cold damage, and you ignore difficult terrain created by ice or snow. The orb has 24 charges, and it regains 3d6 + 6 charges daily at dawn.

Spells. While holding the orb, you can use an action to expend some of its charges to cast one of the following spells from it, using your spell save DC and spellcasting ability: cone of cold (5 charges), fire shield (4 charges; chill shield only), ice knife (1 charge), ice storm (4 charges), Otiluke's freezing sphere (6 charges), wall of ice (6 charges). You can also cast the frostbite and ray of frost cantrips at will while holding the orb.

Frigid Aura. While holding the orb, you can use an action to expend 6 charges to create a raging blizzard around you, extending 30 feet in all directions from you, around corners but not through total cover. Swirling ice and snow make aura's area is difficult terrain and heavily obscure the area to all creatures except you. Strong winds blow through the aura, extinguishing exposed flames and imposing disadvantage on ranged weapon attack rolls that enter, exit, or pass through the aura. Any creature (other than you) in the aura when you create it or that starts its turn there must make a Constitution saving throw, taking 10d6 cold damage on a failed save, or half as much on a successful save. In addition, on a failed save, a creature's speed is reduced to 10 feet until it spends at least 1 minute outside the aura. The aura lasts for 10 minutes or until you use a bonus action to end it.
