No, it doesn't work =(( Maybe the game is bugged? =(( Tell me who you are using as your 4 heroes? You said 3 heroes bought in the tavern... but you can only buy 2 heroes in the tavern because Arantir and his companion are already there - you can't have more! So, you need to free 5 heroes from the dungeon and put them in their place - is that what you mean?? (And I also doubt that the hero you free is a Knight, not a Necromancer? Does that matter?? I've almost broken my monitor from frustration =))
