When to use this shelf
Start here when npcs & merchants is already the named blocker and the player needs a practical route, not a broad article wall.
Merchant rooms and unlocks
NPCs & Merchants database
Browse npcs & merchants entries that lead into real Core Keeper routes.
Use merchant entries when boss drops, room requirements, shop access, or seasonal vendors are blocking the next setup.
These entries answer the first practical question, then hand off into the full page that solves the route, fight, farming loop, or progression problem in full.

What to watch for
The common mistake is treating a database entry like a definition. Use it to decide timing, purpose, next page, and what not to farm yet.
Good next click
If this shelf still feels too broad, use the database index, tools hub, or map before opening several unrelated guides.
When to use this shelf
Use the category after the object is clear, not before.
Know the object already
Start here when the player already knows which item, ore, or boss they need.This shelf is fastest once the object itself has been named.Need one clearer route
Use the shelf when the route is the problem, not the entire save.The entry list points to the next practical page instead of another broad browse step.Need the next handoff
Leave the shelf once the next page is obvious.The linked guide, map, or tool should take over after the database entry narrows the need.Quick entry index
Use one row to pick the right entry before you start bouncing across multiple pages.
