Ragestorm

''Lightning flares up the sky accompanied by a great thunderclap. Dark clouds appear above a creature, and in an instant, the sky opens to unleash rain, hail, winds and lightning.''

Ragestorm creates a miniature Tyr–storm, the affected target becoming the focus of an intense force of rain, hail, high winds, and lightning strikes for the duration of the spell. The storm inflicts 4d8 points of damage to anyone within its radius on a failed save due to high winds, dangerous hail, and electrical discharges. A creature that fails its saving throw can't run out of the area of effect, for they carry the storm with them wherever they go.

If some container is left in the area (and it survives the deluge), up to two gallons of water can be collected.
