Walkthrough tips, Campaign discussion [Heroes 5: Hammers of Fate].

My friend is playing through the campaigns on Recruit difficulty. He sometimes encounters glitches that I have never experienced. However, this only applies to the vanilla campaigns. He hasn't reached "World of Xeen" yet. In my opinion, the campaigns in "World of Xeen" are easier than those in the vanilla game and "The Restoration of Erathia". He completed all of them on Hero difficulty on his first try.
