Demon invasion.

well, in Heroes 5, that turned out to be an unplanned rush – usually, I try to combine speed and map exploration, but that only works with a good knowledge of the map. by the way, your tactic of completing Heroes 5 through the Black Dragon Pit, Machines, and escaping seems to be the only possible one for that hero. I tried to play through Darkness, like the first time, but without the Sandro's Cloak, it turned out to be not very useful, so I also started playing for escaping, but without the Black Dragon Pit and ballistae, I cleared out 3-4 times less than I could have – I was still able to kill mages, but there was no chance against necromancers, so I had to improvise.
