[Deepsea]

I want to point out that wizard is probably the most useful in destroying a forest, and this goes beyond just the kill it with fire. He could use land or hurricane styles to just straight up-root the forest, or just flood it with water styles. Furthermore he could repair the damage done, since from what I recall Helheim is more parasitic then Plant like, and is actually taking space from what was once the earth, by using land styles to cover up the charred remains of the forest, hurricane to spread seeds, and aqua to give water to the area. Or something like that I don't know, I haven't watched wizard yet.
