ah yes, there are a few options:
if Armageddon drops in Heroes of Might and Magic, you can run around with Ifrits and burn everything, but you need to have enough magic power, and a decent mana reserve. Another option is to take Cerberuses or Archdevils, cast Antimagic on them, and then crush them with Armageddon on the next turn. If you're an Earth expert, you can first cast Mass Slow, then run around and hit with Armageddon, but again, it depends on who you run into...
In any case, it's better to take a Mage as your hero. If you're lucky and have the Summon Elementals spell at level 5, you can take the fastest and strongest ones and, in addition to fighting, summon Elementals. But again, you need to have a lot of mana and enough power to summon more than 100 Elementals at once.
