By turn 121, he should be able to break through crypts/ghouls/medium-sized dwarven outposts with minimal losses. By turn 131, the main hero should be around level 15-18. By turns 131-134, he should be able to clear paths to the centers (guard strength of 60; it is recommended to check the guards on the other side of the portal to avoid losing to something like upgraded Rune Priests or Druids). By turn 141, he should be ready to break through the Utopia in the Treasure or clear simple relic guards. If these timings are not met, it means you are playing the early game incorrectly.

The timings for clearing the map are more or less followed; the only thing is that I might be a little late in clearing the center, due to my desire to better clear the adjacent zones with treasures. However, there is a serious problem with the hero's level; I only reach level 18 in the second month. In the first game, in the final stage, I was level 18 in the second week of the second month; in the last game, at the same time, I was level 20. Perhaps this lag is related to the slightly delayed clearing of the center, but in the last game, the opponent cleared the center only a couple of days earlier.
