What to farm
Pick up to four characters from your Character Showcase. The page checks the artifacts they are wearing against the Gear section of their guides and tells you which domain to run next.
Your UID is at the bottom right of the game screen. "Show Character Details" has to be on under Profile > Edit Profile. The characters you want checked have to be in your showcase.
The showcase only holds 12 characters. Swap it in game, wait a few minutes for Enka to refresh, then fetch again. Characters you took out stay on this page. Fetch again after farming to update their gear.

Bold substats are the ones the guide wants. A star after a substat is an extra upgrade that went into it. A useful roll is one best-case upgrade of a wanted substat. A piece worth 4 or more is fine, 5 or more is great.
