Current game. I need about 10-15 mages per army just to have all my Nature+Glamour buffs covered (still buffing 3 tiles per cast). And I'm pumping out +Earth boots, so I will have Earth mages joining up soon, bringing their own sets of buffs. I don't even have any offensive mages this time around. Have 4 armies like this one.
Probably an overkill for normal AI, could just spam summon unicorns and overrun them with sheer numbers, but using magic feels optimal.
