Abstractions and Weather Worker

Weather Worker seems like an interesting spell to use with abstractions. It increases or decreases a weather effect by up to three notches on the natural effects scale. If combined with the Fire element, I guess one could turn a candle into a large fire, or a bonfire into an inferno. And how would one rule with the Anima element, combined with Single Target? Could a stat be adjusted up or down by three? Or would that not fit with the Influence effect?

Those are all great abstractions!

Thanks! Could I use it with Earth to soften and harden, making armour three dice stronger or weaker and give weapons three more or less VA? And maybe I could cause trees to grow and blossom, or whither and die?
