Gameplay Notes

• The passive cannot be activated on hits that deal no DMG, even if they score a CRIT Hit.
• The passive has a chance to activate for each hit that deals damage to an enemy as well as for each enemy hit while the character is on the field. Therefore:
  • Multi-hit skills such as Diona's Icy Paws (5 hits) are more likely to activate the passive.
  • Skills that deal AoE damage such as Venti's Skyward Sonnet are more likely to activate the passive if the skill hits multiple enemies.
  • If the character equipped with the weapon is not on the field when they deal critical damage, the passive will not activate.
• In Co-Op Mode, triggering the passive generates elemental particles for all members of the team.

Description

A secret tome that belonged to the scholars of the Knights of Favonius. It holds the collective knowledge of the scholars.
It is inlaid with crystallized elements, which is what makes the Favonius Codex such a quality.
Not only because the elemental crystals are precious, but also because each Favonius Codex is hand-made.
Only scholars who have mastered the control of the elements can create such elemental crystals.^{[Note 1]}

When the Knights of Favonius was founded, the Dawn Knight Ragnvindr turned the aristocrats' indoor baths into a library.
In time, countless contributions from bards, scholars and travelers turned the library into the largest collection of literature in the northern half of the continent.
After all, songs are whisked away by the wind and wine's pleasure lasts but a fleeting moment. Only that which is committed to the page may sparkle and shine for eternity.

Even so, the scale of the library's collection is now a fraction of what it was at its peak.^{[Note 2]}
For sadly, the library once burned down in the "Great Fire of Fall Equinox" tragedy.

There is a large sturdy door made of poplar wood in the library basement.
It is said the door predates the founding of the library and stood firm against the smoke and flames.
The truth is this door stood there long before the Knights of Favonius was ever founded.
The Knights of Favonius officially states that the restricted section of the library is housed behind the door.
But tales tell of a far more profound secret hidden within.
