The experience gain is decent there ;). But waiting 3 months on this, relatively small map – I can't imagine!
I played as Haggeesh and, with good logistics, cleared the upper level completely in the first month – and by the end of the second month, I started re-taking the utopias (on the 7th week – 6 captures). In total, I reached level 27, and that's without visiting the resource nodes (there are 4 of them).
I encountered the AI on the third week of the second month; it was scouting around in the first week, but I already had 60 centaurs, so it couldn't do much. During the encounter with the AI, I had already taken the utopia (at the beginning of the second month – I lost 10 centaurs and 3 warmongers, using Cyclops as tanks :smile52:).
Playing against the AI isn't very interesting, but here's the situation:
I have: three free Cyclops (eight in the castle), 227 combat centaurs, 380 goblins, 12 shamans, 139 warmongers, 42 warlords.
Wingael has: 66 forest archers, 27 druids, 12 wild ents, 58 golems, 28 light unicorns, 83 wind dancers, 6 dragons.
My stats: 12 attack, 9 defense. Wingael's stats: 3 attack, 9 defense. He is level 15, I am level 19. Losses: all shamans, 4 warmongers, and 20 centaurs :smile52:). It's not interesting to play further; everything is clear now.
Of the artifacts, only the Amulet of Mastery is worth mentioning; the rest is useless.
