Wand of Ash Storm

Wand, rare (requires attunement by a spellcaster)

This wand has 7 charges. While holding it, you can use an action to expend 1 of its charges to create a a 20-foottall cylinder with a 40-foot radius centered on a point you choose within 150 feet. Driving ash blocks all sight (even darkvision) within the spell’s area of effect, and falling cinders cause the ground in the area to become difficult terrain. The effect lasts as long as the user concentrates, up to 1 minute.

The wand regains 1d6 + 1 expended charges daily at dawn. If you expend the wand’s last charge, roll a d20.

On a 1, the wand crumbles into ashes and is destroyed.
