Tips for development in the game.

Personally, I always start by buying a second hero; this helps reduce development time, and having an army early on is always a plus. By the end of the first week, I always have purchased dwellings up to level 3 or 4, one of the two. (level 5 in the Castle and Necropolis). Then, it's worth recruiting an army from the castle and attacking in small groups. In the first week, it's best to take gold from chests; later, the focus should be on gaining experience. And that's basically it... it gets easier from there.
