Book

The Book of Knowledge is where you can check the records and details of all collected Heroes and equipment in Guardian Tales. Access to the Book can be found by expanding the Menu located in the Lobby/Heavenhold screen.

Hero Knowledge

All the Heroes are listed in the Book, where you can view their basic information, their illustrations and read their stories. Some of the information is only available after you acquire the Hero, or even after completing parts of their playable Stories. Character Stories cannot be read before getting the Heroes. Viewing Mode not only has the full illustration, but also list of Voice Lines if the Hero is voiced by a voice actor.

Profile

Lists all the basic information about the Character. This Information includes:

• Evolution Stage sprite images
• Hero Information
  • Height
  • Weight
  • Role
  • Age
  • Species
  • Element

Ability

Character's battle capability can be viewed from the Ability section. It not only lists the basic statistics of the character, but you can view the statistic with different options: Level 1, Maximum level without Limit Break, Maximum level with maximum Limit Break, different evolution stages, Awakening maxed out or not done at all. Besides the statistics you can also view other combat related information:

• Compatible Equipment
• Normal Atk

It is to be noted that these are all Character exclusive abilities and cannot be overwritten or erased by Equipment. Regardless of the Equipment, that hero will use the Abilities listed there.

Progress

Every Hero gives some rewards for pending resources on them. The progress starts by first Acquiring the hero, and then upgrading it as much as possible. Each progress milestone gives you either Diamonds or boosts your Heroes' stats. Completing one Hero's stat boosting milestone, will boost all of your Heroes' stats.

Item Knowledge

• Book
• Collection

Unlike the name suggests, the Item section of the Book only includes equippable items rather than all items in the game. All of these items are listed in the book:

• One-Handed Sword
• Two-Handed Sword
• Rifle
• Bow
• Basket
• Staff
• Gauntlet
• Claw
• Shield
• Accessory
• Hero Costume
• Equipment Costume
• Illustration Costume
• Card
• Merch
• Relic

Whenever you gain a new Item that was not listed on the Book before, you can claim a Diamond reward depending on the item's rarity. The rewards for each rarity are:

• ★ 10
• ★★ 20
• ★★★ 30
• ★★★★ 40
• ★★★★★ 50

Some Items may appear on the book multiple times, as different Star Gradings are considered to be different items, even if they share a name. If you have an item of the lowest possible star grading, you can unlock the higher Star Grading entries on the book by Evolving those items. Once you have unlocked every Book entry there is to unlock for an item, the item will gain a blue tag on the upper right corner which is permanently visible even in your Inventory or when changing a Hero's weapon. If you've unlocked every Star Grading but the blue banner does not appear, the weapon appears in a Collection that you have yet to complete.

An example of Prominence with its respective Collection Banner (Blue tag) and EX Weapon Banner (Yellow tag).

Knowledge Level

Each category of items in Book has its separate Knowledge Level or Knowledge Rank which gains experience every time you gain a new weapon. Each Knowledge Level gives you a boost to your Characters when you have that category's items equipped. Exceptions to this are the costume categories, which will give you a boost regardless if you have them equipped. Each Knowledge Level will increase the boost by 0,1% regardless of the category.
