Building construction order.

Here's a strategy that proved to be optimal on a high difficulty level. 1) Build a tavern and hire a second hero, giving the troops to the main hero. The second hero explores, captures mines, and gathers resources. 2) Upgrade the town to level 4. If you don't have enough money, build a market; if you do, build it after the upgrade. 3) Buy 3 heroes. All three heroes should reach level 5 (3 Stones of Enlightenment are enough, 7500 experience points) and learn the "Economics II" skill (+1 market for the exchange rate) in the management tab. 4) Build a building for skilled creatures (if you have a lot of gold, exchange it for resources at a good rate). 5) Build buildings for elite creatures. 6) Build 1-2-3 fortifications. All of this can be done within the first 2 weeks, ideally along with acquiring some basic creatures. After that, upgrade the barracks. When to attack the second player is up to you; you can hire and attack as early as the beginning of the 3rd week. All other buildings can be built later, depending on your needs and desires.
