Getting started

Craft the book: Book + Compass + Amethyst Shard. Or grab it from the creative tab.

Open it with the item or the key (default K). The index is a grid of structure icons. Locked pages are ???. You fill them by walking into the real thing.

You will get a little action-bar ping when a page unlocks. Open the book later and the page has lore, a short description, mobs, and notable loot with hover names.

Vanilla coverage ships in the jar. A desert temple you have never visited is still ???. Walk in once and it is yours. The book is for people who like knowing what a place is, not a GPS.

If you already /locate everywhere, this still earns its slot. The page is the reminder of what lives there when you go back a week later.
