The change-up between Cyseal and Luculla is an issue; the 'intended' plot path seems to be to go to Hiberheim and explore there (which works) rather than exploring Luculla first (which produces mixed results), but the current setup for entering the cabin means that people are either forced to do the latter or consult a walkthrough. The clues *aren't* really enough to point you to at least the general area of the scroll and the mushroom solution isn't obvious either. Nor is it obvious that you can ask Zixzax about it. He only provides help in the rare case that a quest script specifically calls for it and it's clearly telegraphed every other time, so players aren't likely to think "I should ask Zixzax" when they're stuck on this one.
If nothing else, the statement about the stashed scroll should indicate the general area where the players should look. "The trickster Maradino... on a hill somewhere near here!" would be a LOT more helpful (the former hinting at the whole trap arrangement, the latter telling the player pretty clearly that it's not going to be found somewhere clear across the map).
Aside from that, Luculla also feels unfocused in part because it is. In the Cyseal map you had a big central hub and everything else (both physically and plot-wise) radiated out from it in an internally consistent fashion. Luculla has Silverglen, but it doesn't really serve as a hub for the map, and the various points of interest/relevance are scattered haphazardly all over the place. This isn't necessarily bad in itself, but it's easy to see how that would lead to players feeling lost if they've just come from the Cyseal region.
There isn't really a clean solution to this, but if NPCs in the region - ESPECIALLY in Silverglen - were willing to give directions and/or a description of the major features of the region, it would help a bit. As it stands you can easily leave Silverglen the mining town without any idea of how to reach its mines!
