Upgrade books, statues & heart fragments: effects and locations

Four categories that should not be confused

Books, experience statues and heart fragments have different uses. The atlas records 14 attack-related books and 14 defense-related books. It also records 147 destructible experience sources, plus 24 Brave Heart Fragments and 24 Wise Heart Fragments.

Use the region table below to select the kind you need. Each book or fragment link opens its own location; appearance requirements are noted separately when known.

Brave Hearts and Wise Hearts: four make an upgrade

The game’s tutorials name Brave Heart Fragments as HP upgrades and Wise Heart Fragments as MP upgrades. Collect four matching fragments to increase the corresponding maximum. A single pin represents a fragment, not an entire increase in maximum health or magic.

With 24 documented locations for each type, the atlas covers six complete groups of four HP fragments and six groups of four MP fragments. Do not combine the two types when calculating an upgrade. The upgrade reference page includes the base growth values and direct location links.

The images below are the game’s tutorial illustrations. They help distinguish the two resources; they are not screenshots of the rooms where individual fragments are found.

Attack and defense books: what is confirmed

The map distinguishes attack books from defense books by their effect.

Each attack book adds 1 attack bonus; each defense book adds 1 defense bonus.

When finding a book, first select the Books filter, then open the named point. Its room highlight and neighboring points help distinguish similar rooms. A book may have an appearance requirement. If it is missing, check the room and any progression note before returning later.

Experience statues and XP rewards

Break an experience statue to gain XP. The statue filter lists 147 locations; Brauner’s special puzzle statue is listed separately.

Open a statue for its room position and base XP reward. Experience bonuses and difficulty can affect the amount gained.

A statue shown in a clue illustration may instead be part of a puzzle. Match the category and description before treating every statue-like shape as an experience object.

Use room references to find the right object

Choose your current region in the table below and open the relevant category. The map keeps the pin at the target position while highlighting the containing room. Match the room outline, nearby mirrors, passages and landmarks against your game before approaching the target.

Match the room and nearby clues first. Golden cracks and Chaos Shards have different solutions; compare their appearance with the mechanism guide.

The full book index below links every documented book to its exact map pin. For heart fragments, use the dedicated upgrade page. For a particular statue, use the statue filter and read its individual experience value in the detail panel.
