Worshipper – “Betrayal” [2nd campaign, 1st mission]

O_o In version 1.6, you don't need to defeat the enemy; it's enough to kill the Knight, and you can even lose the battle against the demon, and the mission will still end.

The same is true for versions 1.4 and 1.5. Most likely, this is also the case in other versions, as the mission ends in victory even if you lose to the demon. However, defeating the demon for the sake of enjoyment is quite possible at any difficulty level. In version 1.41, he defeated me as a Warrior. In version 1.5, I defeated him as a Hero. The final cutscene is the same in both cases.
