In the second and fifth missions, he starts with upgraded skills; in the others, he starts from scratch (as the plot dictates).

The Campaign version has been updated. The changes only affected the third map (the Scepter of the Underworld has been added to the list of artifacts). If you have completed the first or second map (I doubt anyone has managed to complete both), you can safely replace the Campaign file with the new one, reload it, and continue playing. The corrected bug is not fatal; it simply means that instead of the Scepter of the Underworld, the hero will have Frída's artifact.
Hey, I have a couple more questions about the second mission:
1) Finding warriors who can join the ranks of the defenders – I found armored warriors, knights, and griffins; who else is left?
2) Is it possible to gain 100 reputation with the Orcs? Orc chieftains on the farm give quests (besides the one where you need to deliver provisions).
3) I still can't talk to the elf leader: the druid says to go to him, I have 60 reputation with them, but when I click on the bridge or gate to pass through, the cursor doesn't change, and I can't move
