Too hot in the Kitchen? (Spoilers)

[Paksenarrion]

I had good luck using demon units. I was level 25 mage when I beat her last night.
Units were: archdemons, demons, demonesses, black knights and red dragons.

I used two demon portals first round, then hypnosis on several imp stacks.
She was so busy killing own troops and summoned demons, that I had time to nuke her units with rage damage and ice snake spells.
