Sacred Haven of Debauchery

I just don't like having to run around a hundred times to buy more troops, and now I'm playing as a succubus, and she has an ability that summons troops, so I just sit there and the army builds up on its own, which is convenient. Exactly, I was just clearing out a dwarven dungeon like that. First, I kill the vampires, wiping out all the metal troops, and then I fatten them up again on miners and other foremen (that feeling when you kill 20 vampires, and they retaliate and restore 25 of themselves). It's the same with elves; first, you eliminate the ents, and then you can calmly build up your forces on druids and their pet bears.
