Wizard – “The Triumvirate” [Campaign 6, Mission 3]

I first swept across the entire map with Zephyr, like with an iron, taking all the towns, and then I went after Godric and Faidaen. Just need to remember to upgrade them later – visit various arenas and planetariums.
Fighting Markel with Zephyr is pure sadism. With Zephyr's "Banish" ability, Markel immediately loses all summoned troops, and hordes of elementals finish off the rest. Markel has no chance.
