A tip for those who have version 1.4 or higher. When your hero reaches level 29, take all the chests only with gold. True, by that time I only had 1 chest left, because I had already taken some chests with gold before. Then you need to return to the level-up point and increase it to level 30. Along the way, you can visit the dwellings and the fortress. You still won't be able to buy and upgrade more than a small part of the units that have accumulated in the dwellings.
