“FULL (almost) RANDOM – VII”

I don't know what to do; the Mage has no regeneration and no resurrection, so should I just focus on Chaos and Summoning? I barely made it through the beginning of the third map with just Mages, and I got stuck in the Snowy Mountains, unable to get Eternal Light, plus I had a week of Emerald Dragons. Basically, I'm getting zero enjoyment from the game. Ugh, these Mages.
