When this appears
PC Gamer places this task in the prologue’s Withering Away quest: Coen prepares medicine from Anca’s instructions to help Esme attend the Blood Mass.
Prologue Help
Anca’s Recipe: Preparing the Prologue Medicine
A narrowly scoped help page for the Withering Away medicine step.
The source notes that the instruction page cannot be viewed while the medicine is being prepared. That is the reason for a focused reference page rather than a broad walkthrough.
Editorial boundary
The published version may give the exact source-verified recipe steps after a spoiler disclosure. Before approval, this draft intentionally does not republish the source’s complete solution text.
