Wand of Winter

From Hoard of the Dragon Queen, page 94.

Description
Wand, rare (requires attunement).

This wand looks and feels like an icicle. You must be attuned to the wand to use it.

The wand has 7 charges, which are used to fuel the spells within it. With the wand in hand, you can use your action to cast one of the following spells from the wand, even if you are incapable of casting spells: Ray of Frost (no charges, or 1 charge to cast at 5th level; +5 to hit with ranged spell attack), Sleet Storm (3 charges; spell save DC 15), or Ice Storm (4 charges; spell save DC 15). No components are required. The wand regains 1d6+1 expended charges each day at dawn. If you expend the wand's last charge, roll a d20. On a 20, the wand melts away, forever destroyed.
