The Foyer is one of those rooms that doesn’t look like much, but quietly changes everything behind the scenes. You won’t find puzzles or items in here—but you’ll stop losing your mind over locked Hallways.

What the Foyer Room Does
The Foyer gives you one big permanent perk:
Hallway doors are always unlocked
Costs 2 Gems to draft
Helps keep your floorplan smooth and accessible
Especially useful if you rely on lots of branching corridors
Once drafted, you can stop wasting keys just to get from one room to another. It applies instantly and keeps working throughout your run.
Placement Tips
The earlier you place the Foyer, the more Hallways it affects. Ideally, draft it in your first 5–10 rooms so it clears the way before you’ve hit a bunch of locked doors.
Final Blurb
The Foyer doesn’t scream importance—but it quietly becomes one of the most useful rooms in the estate. Draft it once, and you’ll never want to play without it again.
