Tavern

If you start on a new city, one of the most important structure, and a relatively easy one to max is the Tavern. If this is not your first city, you can send resources from your bigger cities, so this structure is probably more important than the mines.

The benefits are 2 folds. It allow you to recruit up to 3 more heroes. And daily, with more heroes in taverns, there is a greater chance that you find a green or blue, or if you are extremely lucky, maybe even a purple.

To build the level 5 Tavern, there is a requirement to build a level 5 Hospital, so might as well get started on those too. A level 10 Hospital is needed before you can build a level 10 Tavern. However, there is also a hidden requirement. Even if you can send resources, you to have warehouse and granary large enough to hold the resources you want to receive. So for a level 10 Tavern, there is an unwritten requirement to have a level 12 Warehouse and Granary.
