Does Holo Battle Interlink reward eggs?

The weekly egg sits at 49 stars, and it is a random mysterious egg, so you don't get to pick what hatches. The weekly cap in the first season is 60 stars, which puts the egg near the top of the track. A casual clear won't reach it.

Stars come from damage. You earn one star per million damage dealt to the boss before time runs out. Your weekly milestones count the combined star total across all three routes. Each route records your highest star rank on its own, so improving your weakest route moves you toward 49 just as much as pushing your best one.

The season score track is a separate source of Wonder Eggs. Weekly stars reset, but season progress carries over for the whole season, which lasts roughly 42 days. A week where you fall short of 49 stars still counts toward the season track.

When you can start earning eggs

Holo Battle Interlink is the last endgame mode to unlock. It opens in the second week after launch, on a Thursday. After that it runs weekly from Thursday at 4:00 to Monday at 3:59 UTC+8, and your star rewards depend only on the stars earned in the current rotation. Any stars you haven't banked by Monday's close are gone, and the next rotation starts from zero.

You can also earn by joining other players' teams. Support rewards scale with the highest rank gain you help someone achieve. These are listed separately from your own star rank rewards, and the egg is a star reward.

Other Holo modes that give eggs

Interlink isn't the only option. Hollow Battle Link rewards can include a Wonder Egg, and Holograffiti co-op battle rewards include rainbow eggs. If you're hunting Wonder Eggs, run these as well as the weekly Interlink.

Not settled: The weekly 49-star egg is a random mysterious egg, and the facts don't say which eggs it can roll. They also don't say how many Wonder Eggs the season score track gives in total.
