I think I've described this castle before...
The army is the most effective (I didn't say strong, so there wouldn't be any arguments) – 3 flying units, 2 archers.
Heroes: 1) Gunnar, Alamar
2) Jedid, Damacon, and someone else...
Shakti:smile18: is better +350 gold for the secondary hero.

The secondary buildings are cool.

But I'll list the downsides:
- expensive, both in terms of money and resources;
- sometimes, on random maps, the dungeon is drawn in a stupid location (the mines are nearby, but it's either far to get to them or difficult), and it's not that rich.
- I prefer necromancers!!!
