Tactics for the Stronghold.

2. Fence Piece There are several options here. For example, a good hero, perhaps the main one, is somewhere. He reaches a certain point, does everything he needs to do, and then it takes 5 days to return. In this case, he splits his army and buys new units in the desired location. A similar option: the hero first buys units in a castle with magic (or magic doubling), learns the magic, then splits his army again and buys new units in the desired location.
