I confirm.
Air expert, but couldn't find mass haste, even though I set GM in both castles and ran around 6 of these Sanctuaries, plus the unfavorable landscape, and I lost cleanly in the final. I didn't use Angels because I was focusing on horses and archers, of which I had 100+, however, 80 high-level units with 12 defense (against my 6) easily outshot them. That's it, it was interesting for the first game, we can play again).
