The most challenging maps for you.

From the very beginning of the game, I started using various monster and hero tricks. For example, a year ago, when I was just learning to play, I always chose the Fortress faction because of the Basilisks and restarted the game if I didn't build a level 2 monster dwelling right away. And I immediately loved Supergorgons and used them in large numbers!)))) I'll keep quiet about the rest for now... or I'll remember later.:rolleyes:

Restarting if there isn't a level 2 monster dwelling, I do that too :) otherwise, how can you play on Impossible difficulty?:) And I don't even memorize the names of the heroes. For example, in Champions of Gelu, I had 5 or 7 of them, and I didn't level up the main hero, but leveled up all of them :) Before sailing to the Isle of Knights, I had them and their troops gather in the port near the boat, and I watched who was the strongest, gave him all the artifacts and troops from everyone else, and sent him on a ship to the vortex :) Sometimes, if there were amulets or upgrades, I sent them through the mountains directly to the knights without using the boat :)

The Treasury is a building that generates money. 2500 + 5000 + 10000 (Capitol) - that's 17500. You didn't say at the beginning that you build the Capitol after the troops. For example, I only build the 2500 building when I know that it's extra money and it won't be needed tomorrow (because it will only return in 5 days).

Everyone has their own strategy. Have you played the "Days of Flame" scenario in Heroes 5?
