Commander! I just finished an Aether Raids battle, and this curious scrap of parchment fell into my lap...
Hm? Why, this is a Divine Code! If you collect enough of these, you can compile them into a Combat Manual. Aside from Aether Raids, you can also get these in the Arena and in Mjölnir's Strike.
Wow, really? I thought it was just a fancy-looking piece of parchment... To think that it was part of a Combat Manual all along!
Yes, indeed! And if you create a Combat Manual and unlock its potential, you can use it in the place of a 5★ Hero for things like merging allies or inheriting skills!
I never realized that a manual could be so useful! I'll have to keep an eye out for opportunities to earn Divine Codes!
Oh, but bear in mind that there are two types of Combat Manuals—normal and time-limited. You'll need different Divine Codes depending on the type of Combat Manual you want to make.
About Divine Codes
Divine Codes are items that you can exchange for Combat Manuals once you've collected enough of them. There are two types of Divine Codes: those that can be redeemed for normal Combat Manuals, called Divine Code (Part X), where X stands in for a number, and those that can be redeemed for time-limited Combat Manuals, called Divine Code (Ephemera X).
How to Collect Divine Codes for Normal Combat Manuals
The Divine Codes used to create normal Combat Manuals will have names like Divine Code (Part X), where X stands in for a number. You can receive these through Mjölnir's Strike tier rewards, as well as through other sources like tier-based rewards in Aether Raids and the Arena.
How to Collect Divine Codes for Time-Limited Combat Manuals
The Divine Codes used to create time-limited Combat Manuals will have names such as Divine Code (Ephemera X), where X stands in for a number. You can receive these as rewards in the Tempest Trials and Lost Lore events. Additionally, Ephemera numbers will rotate every month, corresponding to different Combat Manuals to compile.
