While Kingdom Come: Deliverance 2 features numerous serious narratives involving clan conflicts and cultural exploration, the Demons of Trosky quest stands out as an intentionally frustrating experience that feels like an elaborate practical joke. This comprehensive walkthrough provides essential guidance for navigating this challenging side mission successfully.

The Demons of Trosky side quest occurs during the initial campaign phase and features one of the game’s rare guaranteed failure conditions if you cross an irreversible threshold. Understanding these critical timing elements is paramount for completion:

  • This mission unlocks immediately after finishing For Whom the Bell Tolls. Speak with chamberlain Ulrich to learn about sinister entities inhabiting Trosky Castle’s depths. During this conversation, you can request holy water or mystical water from Ulrich, which may prove useful later.
  • You maintain eligibility for this quest until initiating the primary mission titled For Victory. When For Victory appears in your quest log, refrain from engaging with Hans Capon to preserve your opportunity.
  • The Demons of Trosky mission in Kingdom Come: Deliverance 2 comprises three distinct investigative phases that must be completed sequentially. One narrative thread involves blacksmith Osina’s accounts of a paranormal gateway through which shadowy beings escape. He directs you to examine three specific latrine sites in this exact progression order:

  • The latrines adjacent to the dueling practice area – typically bustling with activity during daylight hours.
  • The latrine situated near Von Bergow’s private chambers – often less crowded but requiring careful navigation.
  • Finally, the latrine located on the staircase landing beyond the scribe’s workspace – this final location may require persuasion or stealth depending on your character’s skills.
  • Blacksmith Osina's tasks

    Osina maintains his characteristic unpleasant demeanor throughout these interactions. His consistently disagreeable attitude suggests this represents his standard behavioral pattern rather than situational hostility.

    Successfully navigating the Demons of Trosky quest requires awareness of several advanced gameplay considerations that many players overlook during their initial attempts.

    Critical Timing Awareness: The most common failure point occurs when players advance the main storyline prematurely. Once ‘For Victory’ activates, this side quest becomes permanently inaccessible. Plan your gameplay to complete Demons of Trosky before engaging with major narrative milestones.

    NPC Interaction Optimization: Osina’s unpleasant demeanor actually provides gameplay clues. His consistent hostility indicates this isn’t personal – it’s character design. Use this understanding to manage your expectations and approach interactions strategically rather than emotionally.

    Resource Management: While obtaining holy water from Ulrich is optional, it can provide alternative dialogue options and potentially different outcomes. Consider your character build and playstyle when deciding whether to acquire these items.

    Action Checklist

    • Investigate the three latrine locations in exact sequence
    • Complete all quest segments before initiating ‘For Victory’ main quest
