The most challenging maps for you.

What does "killed 9 spectral dragons for the angel alliance" mean? Did you kill 9 Necropolis dragons with a Castle army? What does "with stats of around 30 each" mean? Does the Elixir of Life give some kind of bonus, is it an artifact? How can you remember all this in such detail? I still don't know the map very well. I don't even touch the Dweller dragons. I always unlock the Dweller of Angels. In Expert mode, I had 15, 20 Dweller of Angels in my 2nd and 3rd armies by around day 50. Then I play with a fast-paced strategy because I'm not playing for the result, but to learn the map, so many troops die. The map is large, and because I don't know the map very well, I don't develop the heroes much. I capture some Town, leave a hero there to rule the territory, and send another new hero to another Town. And for about 7 days, I just take turns, not knowing where the last living hero is, and I'm too lazy to look. 60+ days is a good result for you! On large maps, it's probably better to develop Logistics and Scouting? I'll play Impossible mode manually. Although, honestly, I'm already tired, I won't play today :).
