Sandstorm Staff
Staff, Uncommon (Requires Attunement)

Many of the discarded weapons of the Last War have found their way into the hands of the people of the Barrens. This sliver of a broken Siege Staff can deliver a powerful punch when it needs to, but ejects an exhaust of swirling dust when exerted.

This staff can be wielded as a magic Quarterstaff. The staff has 10 charges and regains 1d6 + 4 expended charges daily at dawn.

When you cast a spell using this Staff as a Spellcasting Focus, you can expend 1 charge to gain a +1 bonus to all spell attack rolls you make for that spell. If you do so, the staff conjures a 5-foot diameter vortex of dust in your space. At the start of each of your turns, roll a d20 for each dust vortex the staff has created. On a roll of 11 or higher, the dust vortex moves 5 feet in a random direction. On a roll of 10 or less, the dust vortex disappears.

Any creature that starts its turn within 5 feet of any of the dust vortexes must make a Constitution saving throw against your spell save DC. On a failed save, an affected creature takes 1d4 Bludgeoning damage and is Blinded until the end of its turn.
