How do you do that? I don't quite get it... and he just takes them out right away.

Yeah, well, that's how it is :) A new location means a new battlefield. In the first 3 times on the battlefield, there wasn't even a single rock to hide behind. By giving the enemy an advantage, I won because the new battlefield had 2 rocks and a log in the corner, and they were on my side. I hid the centaurs behind the log and placed the shamans on the side, making the archers unreachable for melee attacks. In "Hammers of Fate," you can safely forget about a function like "autobattle." You can complete "Hammers of Fate" without straining your brain too much thanks to autobattle. But here, if your army is twice as large as the enemy's, you will lose 2/3 of your troops, and the most valuable ones at that, if you even win the battle. In general, I recommend losing 2-3 battles to the enemy to see which units the computer relies on and which ones it tries to eliminate first on your side. Analyze and build a battle strategy based on the data you get. After all, strategies are aimed at developing logic and thinking ;)
