Tactics for the Swamp (Fortress).

A wonderful race. Interesting to play.
Much has been said. I would like to add that this castle is simply made for raiding treasure vaults for resources. It is so easy to do this while playing as this race, thanks to its focus on defense and the characteristics of its units. Well, everyone knows about the draconian utopias; reckless hydras and gorgons with sturdy basilisks will do their job with minimal losses. Wyverns will protect their own units, and it is also easy to raid other treasure vaults by combining the composition of creatures.
Of course, you might say that it is convenient to raid treasure vaults with any race, and maybe it is... but try to do it with the Swamp!
