Peter Stamatin's Blueprints

Peter Stamatin's Blueprints is a quest item in Pathologic. It is obtained during the Bachelor's route on Day 10 for the main quest "Clarity and Focus."

In order to obtain Peter Stamatin's Blueprints, the Bachelor must first find Peter Stamatin hiding next to a Stairway to Heaven. He will be disguised as an orderly. Peter asks the Bachelor for five bottles of Twyrine in exchange for the Blueprints.

"Blueprints of the Polyhedron lined with tracing paper and containing a detailed description of the structure. Also contains faded written copies of various treatises on optics, some in foreign languages. Gives the impression of a standalone monument of human thought."
