I watched a couple of other saves where they hit ГО on Jebus Cross in the 2nd week.
Heroes there are already level 15, 20 everywhere. I checked the respawn, all the crypts and dwarven mines are not taken, a lot of resources, even chests are lying untouched on the respawn. Cons are also not taken, some of the Hives are also not taken. How and where do they level their hero like that then? I only have one thought, that there were several Pandora's Boxes with experience.
High-level heroes can not only be obtained through leveling, but also freed from a prison.
