This was the most difficult mission I ran into so far, and that's only for the first 10-15 minutes (really, that long for me). I had to restart about five times, because I was getting overwhelmed using a tower-build strategy, a rangers guild strategy, etc, etc.
What I landed on was the following:
- Tower of Lords first, and only this (once this goes up it has a ton of HP and is difficult to take down)
- Hire a fighter lord - you need someone who will patrol the town and like fights
At that point, I was pretty much untouchable, because I had such a strong defensemen, and most of time I had to concentrate on building an economy, which took forever
- Build three towers and upgrade all of them
- Build a rangers guild and start exploring
- Build a fourth tower, upgrade it
- Situate your market in between some towers - I had wanted to build a market sooner, but it kept getting destroyed. I need four towers to defend it
- Clerics guild
- Blacksmith
- Warriors Guild
- Wizards Guild - Wizards towers
By this time the mission is very easy and is mostly just fun clearing out the map.
