Bring Rinny along Transylvania talking to the random people around the town, all the way to the locked gate?
I could list out but, specifically point out where you are currently.
You lose Rinny to the mirror? In the catacombs Rinny will be taken and you have to find a sanctum holding a searchable casket in the middle, let those catch you. (Finish this to progress most of these, you need a good chunk of items from that graveyard.)
Pyramid map is somewhere inside the slavers cave, find him to obtain the real one(Fake maps still get you rare devices)
Abandoned town, to progress Cassie further she needs a bandit dog that wanders the town road(kidnapped), refurnished basement with torture devices, and. A tiger boy wearing a maid outfit(soiled).
The abandoned lab needs Linda, the deeper forest needs you to make cheese and find the fairy queen, ask her about the very tough plant: offer cheese.
