Tactics for Dungeon.

To be honest, I don't play Dungeon. But with the troops I mentioned, I'd take on 16 Knights and a Dragoness. If, for example, the third hero has 14 Centaurs and 4 Gnomes, I think there will still be a decent number of Trolls left. Of course, Offense needs to be raised to Expert, Tactics at least to Advanced, or have Bless. In short, one or two triple stacks need to be eliminated in one hit. I think it will be possible to defeat the Knights, leaving about 90 Trolls alive. Without "unrealistic" battles, I don't think it's possible to win against a reasonably strong player.
