Wand of Winter Storms

Wand, very rare (requires attunement by a spellcaster)

This wand is made of translucent crystal and resembles a slender icicle. It has 7 charges and regains 1d6 + 1 expended charges daily at dawn. If you expend the wand’s last charge, roll a d20. On a 1, the wand melts and is destroyed.

While holding it, you can use an action to expend 1 or more of its charges to cast the ice storm spell (save DC 17) from it. For 1 charge, you cast the 4th-level version of the spell. You can increase the spell slot level by one for each additional charge you expend.
