Arcane Focus of Frost

You have resistance to cold damage while you hold this Arcane Focus.

The Arcane Focus 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: Ice Knife (1 charge), Wall of Water (3 charges), or Ice Storm (4 charges).

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