Finding the Royal Treasury Key in Kingdom Come: Deliverance 2's Oratores quest can be tricky. This guide provides a clear walkthrough.
The Oratores quest is lengthy. After discussions with Rosa and Zizka, you'll need Vavak's assistance with a theft. The next objective: acquiring the Royal Treasury Key.
Locate the outhouse (toilet) in Vavak's backyard. The map below shows its precise location.
Examine the toilet bowl; an "Investigate" prompt will appear. Clicking it will reveal the key. This will dirty Henry, so wash up afterward to avoid issues with dialogue checks.
With the key, return to Zizka and Rosa, then explore the underground passages with Samuel. The quest continues beyond this point.
This concludes the guide to obtaining the Royal Treasury Key. Check out The Escapist for more Kingdom Come: Deliverance 2 tips, including Lower Semine woodcutters' treasure locations and optimal perk selections.
