"Rolling gouts of bright-green flame roar across the area, consuming all that they touch - but these flames carry no heat, and where they pass, objects and creatures do not burn, but melt, pitting and dissolving as though subjected to a powerful corrosive agent."
Similar sort of thing for acid-substituted lightning bolt etc.
