A while ago I played the Conquest of the Arctic campaign. While it was overall ok I still have no clue how to solve the moon level.
There are three enemy keepers which can be rather easily defeated. But that´s not the winning condition. This is the destruction of the hero dungeon heart. This is however walled off and not reachable.
There is also a walled-off room with a hero Avatar and neutral vampires. And another one with some boxes.
Some spell books are there, but can´t be used due to lack of a library.
So, any idea how to win this? I tried to attack with the drain spell or meteor of my Avatar in possession mode through the rift of the corner of the walled-off dungeon heart room. Of course no success.
Maybe someone has solved this level.
