System mechanic — not a missing feature

The In-Game Guidebook

Opens with [.] (period) · a built-in reference panel already inside the game

This isn't a page about a missing feature — it's the opposite. The game already has its own built-in reference panel, described in its own controls list (press F1) as "the guidebook — every system in the game, explained." If you haven't found it, press period. This page exists to point you at it, explain what it's good for, and be honest about where it stops.

It's the deliberate counterpart to The Tutorial new characters are offered — the tutorial teaches the verbs (the things you actually do), and this guidebook is where the nouns (the systems and vocabulary behind them) live.

What it's for, and why it's built the way it is

The guidebook is explicitly built to read live facts out of the game's own data — item counts, mob counts, skill counts, dungeon requirements, gate levels — rather than having those numbers typed in by hand. The reasoning, stated directly in the game's own source: a typed-in number goes stale the moment a rebalance happens, while a number read from the actual registry at the moment you open the panel never can. That design choice is why this wiki treats the guidebook as trustworthy for anything it states a number for.

It covers, among other things: total items, creatures and skills in the game, the level curve's true ceiling, the world-travel level gates, the dungeons and their requirements, the vehicles you can craft and fly, the Spire's mastery-rank system, oaths, the bestiary, and the collection log.

What it's NOT for

The guidebook is a facts-and-numbers reference, not a deep explainer. It'll tell you a dungeon's level requirement exists; it won't walk you through that dungeon's specific boss mechanic the way this wiki's dedicated pages try to. Think of it as the game's own quick-reference index, and this wiki as the place for the full story behind anything the guidebook only gestures at. It's also a different system entirely from the Endless Guide, the game's ongoing, on-screen task system — this page is about the [.] reference panel specifically.

It didn't start accurate — worth knowing before trusting an old memory of it

The guidebook shipped and spent roughly the next thirty versions being corrected, piece by piece, as gaps and mistakes were found:

• For a long stretch, entire systems weren't mentioned in it at all. Dungeons — eighteen of them, each with its own requirement and boss — weren't named anywhere on the page for a long time. Vehicles got one passing mention in a list of things crafting produces, and the guidebook never once told you that you can fly, until that was fixed. Oaths and the bestiary, both named in the game's own writing elsewhere, weren't explained here until later still.
• Some of what it said was actively backwards. The page hinted housing affects how much the Dream follows you home, without ever saying which direction — and the natural assumption (the expensive house is the safe one) is exactly wrong; see that page for the real relationship.
• Some of its "live" numbers were quietly fake. A few facts were typed in by hand during an early draft — precisely the staleness this panel exists to avoid, and one hardcoded figure even named the wrong thing being counted. A subtler case had a fact silently broken since the day the page shipped: the read for "how many spells exist" threw an error internally, every single time, for over twenty versions, and nobody caught it because the fallback value it silently used happened to already be the correct answer.

None of this affects the current guidebook — every one of these was found and fixed, and the panel now reads its numbers live, the way it was always meant to. It's listed here because a wiki page claiming "the guidebook already covers this, trust it" should be honest that trust had to be earned first.

Trivia

• The guidebook's own key was originally semicolon — it moved to period specifically because the spellbook (a different panel entirely) already owned semicolon and got there first.
• For a while, the game's own F1 controls list didn't mention the guidebook existed at all, meaning a new player pressing F1 to learn the controls had no way to discover it.
