Storm of vengeance

Storm of vengeance was a conjuration spell that called a mighty thunderstorm, causing acid and hail to rain down on foes, as well producing booming thunder.

Effect
This spell created an enormous black storm cloud. Lightning and crashing claps of thunder accompanied the ominous bank of dark clouds. Creatures beneath the cloud must have been able to withstand the effects, or otherwise be deafened for up forty minutes.

The caster had to maintain concentration on the spell after casting it, otherwise the black storm would dissipate. If the caster was able to continue to concentrate on the spell, additional effects occurred every six seconds:


 * Acid rained down in the area, which foes were unable to escape from.


 * Six bolts of lightning were sent down from the cloud, and the caster could choose exactly where they struck. The bolts dealt huge damage, but creatures with quick reflexes could avoid a portion of it.


 * Hailstones rained down on those within the area, which were impossible to dodge.

After the initial period, the storm would become extremely intense:


 * Rain would descend rapidly on all in the area, and the invoked winds would become extraordinarily strong. Both weather effects largely reduced visibility, so even creatures with darkvision were unable to see in the chaotic conditions. In the turmoil, all creatures would become far slower, and ranged attacks literally became impossible. Only the most skilled mages were able to pull off spells in this region, and required a large amount of concentration.
