I found a very quick way of finishing the Spooky Hollow scenario (took me 3 minutes).
1) cancel intro cinematic ASAP (right after scenario is loaded) 2) use a ghost with Hidden Maze power 3) as soon as scenario starts bind that ghost and use Hidden Maze
If you are fast and lucky enough, the portal will spawn on Windmill doors just as the Evil Cousin is walking through them.
After he is teleported he starts walking slowly towards the edge of the map. Scare him away and you'll win the scenario when he reaches the edge.
The drawback of this strategy is that The Dragoon will not be laid to rest.
NOTE: luck aside, the time window to do this is really small. I managed to do this without mods by rotating camera quickly and binding Blue Murder to deer bones in front of the bridge. If you are having trouble try the "Inside/Outside On All Ghosts" option of my MiniEditor, then you can bind the ghost wherever.
Good strat! This helps, because im trying to beat the game with least ghosts laid to rest possible. I spent so much time trying to complete weird seance without freeing wendel, but i gave up on that. RN im trying to do cal horror with unlocking only 1 ghost.
