Toxic downpour

Convert all the present clouds into acidic clouds which pour acid onto all enemies within range of the clouds, this rain only effects those outside without sufficient cover, anyone inside cover of materials such as metal, stone, and other sturdy structures, materials such as wood, leaves, and other organic materials will decay under the effect of the toxic downpour.

Allies will not be effected severely by the rain, however will feel small irritations to exposed skin, enemies that have little protection will suffer the effects of acidic lament and deal a scaling amount of damage to how long they stay undercover.
