The Tome of Power turns gear you have earned into permanent passive buffs. You register an item into a slot, the book scores it, and reaching a point threshold on that line grants a buff that applies whether or not the item is equipped.
Open it with the Tome button in your inventory window.
One line per dungeon
The book has 61 lines, one for each dungeon or raid at a specific difficulty - jump between them with the dropdown at the top of the window instead of paging through. Each line has its own ten slots, and every slot on a line you can access is open at once - there is no separate level or job-step gate inside a line.
- Each of the fourteen story dungeons - Deepworks, Faunus, Towa, Drakeshade, Frostdrake, Frozen Time, Ancient Memory, Marionette, Sunken, Hephaestus, Ethon, Erebus Gate, Lethe and Tartarus - has four lines, one per rarity of gear it drops: Verde, Rosa, Azul and Laranja, labelled (E) Easy, (N) Normal, (H) Hard and (F) Final in the dropdown.
- The endgame raids add five more lines, labelled (R) for Raid: Thunderdrake, Agony, Narak, Chained Titan, and the top line, Olympus.
- A line only takes gear from its own dungeon and rarity - the slots are whitelisted, so a Deepworks Verde piece will not fill a Faunus Rosa line. You unlock a line by reaching the level its dungeon asks for, the same level shown on the Dungeons page.
How an item scores
The same three things score every item, on every line:
| Contributes | Weight |
|---|---|
| Rarity - Normal, Magic, Set, Rare, Unique | the largest share, over half |
| Level requirement of the item | roughly a third |
| Refine grade, +0 to +10 | the smallest share |
What differs per line is the ceiling: an early Deepworks line tops out a little over 300 points, while the top Olympus line goes to 900 - each line's milestones scale to the gear that content actually drops. Buff marks sit at a quarter, a half, three quarters and the full line, and a partly filled line already pays something below the first mark rather than nothing at all.
This weighting is deliberate. Rarity and level mean content you cleared; refine mostly means gold you spent. The book is meant to record the first.
What it grants
Each threshold grants a passive buff, and the buffs differ by class - the tome reads your job and gives your line the stats that suit it, rather than one flat bonus for everyone.
The Display Stats popup groups every set's bonuses together, with a colour per rarity and the point total updating the instant you add or remove gear, so you can see what a line is paying without leaving the window. It also shows each line's maximum for every attribute, and the four small ones - Life Steal, Critical Rate, Critical Damage and Aggro - are shown to a tenth of a percent.
Slot 10's ring (Band of Might / Band of Insight) is crafted like the line's slot-9 ring - see Crafting.
Two things to remember
- Extracting an item lowers that line's total, and can drop you back below a threshold you had passed.
- Register the best version you own for that specific line. A Unique at a high level with a decent refine is worth several times a common piece, and the slot is the scarce resource, not the item.
Where to go next

- Reinforcing - the refine grade the book counts
- Raids - the five endgame lines
