Dark Messiah

I personally can't figure out how to defeat the Orc that appears after all the altars are activated. I've tried various approaches, and nothing works. If anyone has managed to do it, please share your strategy.

I personally completed it like this: First, I eliminated the Necromancers on the starting island and gathered all the available troops. In the southeastern part of the map, there's an upgrade facility for units. Before boarding the ship, I upgraded all the collected units and sailed to the island whose section was revealed. There are still some mages there, but I sailed north to another island. On this island, there are two quests. After completing them, Paladins and Knights will join from the monastery, and Titans and Mages will join from the mage building (sorry, I don't know what to call it, something like a flying Temple). There's also an upgrade facility on this island. I upgraded the entire army and sailed to the small area that opened up to the south. I recruited the Mages, and voilà... my army consisted of, let me see, approximately 7 Titans, 10 Paladins, about 60 Knights, 65 Mages, 100 Archers, and 140 Longbowmen... I easily cleared the island with the Orcs. I entered the Dungeon, prayed at the three altars, and defeated the Orc. It's a shame that everything was taken away afterward... :( I had a lot of artifacts and was level 24... :smile19:

P.S. Oh, I forgot to mention that, of course, I eliminated all the neutrals and collected all the artifacts everywhere. For the free ability, I chose defense...
