2. Salomon's Chaos magic is very useful. An explosion with the "Mark" spell is deadly to enemies. It won't outperform Dungeon magic, of course, but it will be very close. As for whether Light magic is needed here, I'm not sure. In general, Light is needed for warriors when the hero moves less often, and the troops should move more often. But for mages, on the contrary, Darkness is more useful, so that the hero moves more often than the enemy's troops, because he is the main force.
