Tactics for the Swamp (Fortress).

There are no inherently "wrong" factions; the tactics simply differ significantly between the various Castles. Here's my advice: 1) Almost all of the Swamp's units are masterpieces. Discard the first two. Fly Traps give you the first turn due to their enormous speed for that level, and they inflict a weakening effect on the enemy while removing positive spells. This is better than applying debuffs to the enemy yourself. Basilisks are a very fast unit that can petrify enemies. Furthermore, there's a hero with whom you can acquire them early in the game. Gorgons are excellent for eliminating the enemy's last unit. Wyverns, which you purchase early in the game and which gather in trees, become numerous by the mid-game. Wyverns are a cheap and very effective unit (when used correctly). 2) The Castle has several structures that enhance its defense. 3) You should focus on developing an exceptional warrior and tank, without trying to specialize in magic. 4) In the early stages, you should build Wyverns and profit from them. This is the second Castle, after the Barbarians, that has access to great units early in the game, and you should take advantage of this.
