Early Trosky: one wedding route first
Kreyzl’s three-part route teaches theft and leads into the wedding. Radovan offers the blacksmith route. Pick the one you want to play first; you do not need to complete both just to gain entry.
Companions and rescue follow-ups
Mutt can be recovered directly at the cave near Lower Semine. If you start Lackey, save Vostatek without abandoning him; Bird of Prey depends on his survival. Group the herb-shopping trip with your next village visit.
Before a feud resolution
For both prank quests, use Frogs then Mice before Battle of the Frogs and Mice. This is a dependency, not a requirement to finish every Trosky quest in that order.
Kuttenberg after Speak of the Devil
In Vino Veritas and Ars Dimicatoria start in the city. Ransom and Thunderstone send you farther across the region. Start from the relevant giver and finish the current investigation before beginning another long travel loop.
