Genshin Impact: Favonius Codex – How to get it, stats, and ascension materials

Does the Codex rise above the competition?

The Favonius Codex is a 4-star weapon, a part of the Favonius Series of weapons that benefit support characters. The Favonius Codex is a strong option for any support character who wields a Catalyst, allowing a character to generate massive amounts of energy particles after dealing critical damage. This allows any sub-DPS or support character to funnel energy to any character.

As a 4-star weapon, the Favonius Codex is obtainable from the Standard Banner, the Featured Banner, and the Weapon Banner. You can get this weapon at any time from all three banners, making this an attractive option for free-to-play or low-spending players. Occasionally, this weapon will have a rate-up on the weapons banner, so keep your eyes peeled if you need this weapon.

  • Rarity: 4-star

Is the Favonius Codex any good?

Like the other weapons in the Favonius Series, the Favonius Codex is rarely the best-in-slot for any Catalyst supports in the game. This is compounded by the fact that most Catalyst supports would rather use a superior weapon that’s much easier to obtain than the Favonius Codex.

The Thrilling Tales of Dragon Slayer is a 3-star Catalyst that provides a huge ATK buff to the character you swap to. The Thrilling Tales is generally more useful than the Favonius Codex, and it’s much easier to obtain due to its status as a 3-star weapon.

Unfortunately, due to direct competition, the Favonius Codex is generally not recommended for any character. If you have intense Energy Recharge issues, you could use the Favonius Codex to rectify that. Otherwise, stick to the Thrilling Tales weapon.
