Story
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 rarity.
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.
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.

FAQs
Is Favonius Codex good?
Favonius Codex has a clear function as fueling your teams Elemental Bursts through the particle generation of its passive, as well as its Energy Recharge stat. From a utility standpoint it is certainly a solid option. It is definitely subpar in just about any other context though, with its low base ATK and lack of a major offensive substat.
Who are some of the best users of Favonius Codex?
Mona and Lisa are two of its best users, typically filling Sub DPS/supportive roles in teams and having multi-hitting Elemental Skills/Bursts in order to maximize the chance of activating the Windfall effect. Mona especially benefits with one of her talents converting her Energy Recharge into Hydro DMG.
Is Favonius Codex anyone’s BiS?
While it is a solid utility option, there are typically more superior options for its potential users.
Even its best user in Mona would definitely prefer the Widsith. Still, it is more than effective for its intended purpose
Final Thoughts
Favonius Codex is a weapon that fully sells out for utility and supporting your teammates with its Elemental Particle generation via its passive, along with its Energy Recharge substat. It works well for this purpose, but is definitely not one of the best options if you’re looking for something to give your characters a bit of oomph in the damage department.
