They're very nasty front line vomiting flame eruption as Wingeddog learned me upside my face. Give them some black hunter bodyguards, run forward one turn and cast flame eruption. Second form keeps them from dying from an unlucky hit so you can use them in close range, and 3-4 of them doing this will annihilate huge swaths of most troops. That's 26+ AP damage with a 15 AOE and they can cast it several times as fresh troops climb over the charred bodies of their front lines.
