Blueprint



"Meticulous architectural sketches of Hamlet structures."

- In-game description

Blueprint is Rare heirloom that is used to erect new buildings within the Districts of your once prospering Hamlet. Blueprint is an exceedingly valuable drop from Bosses, but one will be gifted to you on Week 10 (or as early as Week 7, depending on your unique circumstances), allowing you to construct your first District building. Blueprint does not drop from mini-bosses such as the Collector or the Shambler, making it fairly hard to acquire in large quantities.

It also seems that Blueprints do not drop from Bosses of Expedition difficulty 1, but this information is not verified. -Verification Required-
