Herbicide

Herbicide [minor] by Iczer

'Beloved asphalt...How your beauty has been tainted by these weeds. I shall cleanse this blight'

The character can kill plants. More specifically, he can shoot a specialized and virulent acid that targets cellulose and chlorophyll. The character's acid spray shoots for 30 feet and has a +4 to strike, though by broadening the spray, he can reduce the range to 10 or so feet but doubling his bonus to strike with it.
Soft, green plant matter, such as mold, fungi, slime and grass simply turns brown and dies on the spot wherever it is touched. Sturdier plants take 6D6 damage per spray, and if living, are horribly poisoned. Plant creatures suffer the same fate, and even dead and treated wood suffers the burn of this acidic release.
