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, a significant main quest, involves securing Vavak's assistance after speaking with Rosa and Zizka. The next objective: obtaining the Royal Treasury Key.
Locate the key within the outhouse (toilet) in Vavak's backyard. Refer to the map image below for its precise location.
Examine the toilet bowl; an "Investigate" prompt will appear. Clicking this will reveal the key. Note: this will dirty Henry, so wash up afterward to avoid dialogue issues with NPCs.
With the key acquired, continue the quest by speaking to Zizka and Rosa, then explore the underground passages with Samuel. The Oratores quest is lengthy, so prepare for a substantial time commitment.
This concludes the guide to obtaining the Royal Treasury Key. For further Kingdom Come: Deliverance 2 assistance, including Lower Semine woodcutters' treasure locations and optimal perk selections, consult The Escapist.
