Ash Storm

Ash rains from the sky in a swirling storm of burning cinders centered on a point you can see within range. The storm fills a 20-foot-radius sphere.

When the storm appears, and when a creature enters the area for the first time on a turn or starts its turn there, that creature must make a Constitution saving throw.

On a failed save, the creature takes 2d6 fire damage and 2d6 necrotic damage, and its speed is halved until the start of its next turn.

On a successful save, the creature takes half as much damage, and its speed is not reduced.

The ground in the storm’s area becomes difficult terrain for the duration as ash and cinders accumulate.

The ash cloud heavily obscures the area.
