The Favonius Codex is a four-star catalyst in the Favonius weapon series. Its Energy Recharge substat and Elemental Particle-generating passive makes it an optimum choice for sub-DPS characters who require a large amount of Energy to maintain their Elemental Burst's uptime. With so many catalyst users who fall under this category, the Favonius Codex is a versatile weapon choice that can be shared among your character lineup.
How to get Favonius Codex in Genshin Impact
Favonius Codex is a standard banner weapon, which means that you can pull for it on the Wanderlust Invocation, as well as all limited character and weapon banners. However, it's sometimes on rate-up in the Epitome Invocation banner, which you can pull on using Primogems and Intertwined Fates. Being a four-star weapon, you can't chart an Epitomized Path for Favonius Codex. Obtaining it comes down to pure luck.
