[ХL]: "Flor's Trial"

The first battle is quite manageable (I managed it on my second try – I just made a silly move with the Ents). You are seriously underestimating these griffons. The other upgrade has almost twice as much health, but these are more effective. Before they died, they took out all the archers and knights (and the liches about three times) and damaged the ghosts. It’s a shame they fell. Besides them, the losses were 4 crossbowmen. Perhaps, if you replay it a couple of times, you can save about 8 of them, but around 10 crossbowmen will die.
