The most challenging campaign.

it takes a while to collect the artifacts, and when Nicholas started running away from me in the last mission of the Ranger, that was something else! I cursed for a long time and chased after him for a long time too; I think this mission is the most difficult. It would have been better if Nicholas didn't run away but engaged in combat!

and I also struggled for a long time with the 3rd mission for the Demons...
