Blue Prince item questions players ask

Where do the item details come from?

Item names, descriptions and locations are pulled from the Blue Prince wiki ItemInfobox via the MediaWiki API, not from memory.

Which items matter most for a first Room 46 run?

Items that open new rooms or solve a puzzle you are stuck on. Keys and special items are the ones worth routing a draft around; the rest are situational.

What does "Locations" mean?

The Locations field records where the wiki lists the item as obtainable. Not every item has a known location listed, which is why the filter separates the two.
