"It depends on how the fight goes. It's very difficult to defeat 2-3K golems; half of the spells don't affect them, and combat spells only deal 25% damage. But generally, a single archmage at level 40 can easily defeat 1000 behemoths, meaning creatures."
"The point was this), and there's not a word about tactics here. I figured that an archmage at level 40 can't fully master more than 3 schools (based on the fact that it takes about 15 levels to learn one school)."
"If you also add tactics, then it's no longer a 'pure' archmage."
