Just reading through Vaesen in advance of running it. We have an Occultist with the Medium talent. I was looking at the castle upgrades and see there is a Seance Parlour listed which allows PCs to have a Seance before a mystery and gain clues. My question is what is the advantage of this? Why can't they just have a Seance anyway? There doesn't seem to be a restriction on the number of clues they can gain otherwise.
p 199 does say that PCs can roll LEARNING in the library or university. Does that therefore mean they cannot use any other skills/talents without the appropriate upgrade? That seems to be the implication but it seems a bit odd.(And it's in the adventure, not the actual rules)
