Limited-Time Incubator

One limited-time incubator will be added to Bellis’s Lab for the duration of this event. Try hatching lots of Eggs during the event period!

Note: If an Egg is still in the limited-time incubator when the event ends, the limited-time incubator will remain active until that Egg hatches.

Lineup Bonuses

You have an increased chance of receiving Eggs if you take on event battles using teams that feature specific sync pairs. The more of these sync pairs you place in your lineup, the higher your Egg reward rate will be!

Note: The Egg reward rate is limited to a maximum of 100%.

Applicable Sync Pairs

• Main Character Sync Pairs Egg reward rate: ×1.4!
• Grass-type, Fire-type, and Water-type Main Character sync pairs Egg reward rate: ×1.8!
• Grass-type, Fire-type, and Water-type sync pairs Egg reward rate: ×1.2!

The lineup bonus is ×1 by default and varies according to which Sync Pairs are on the team.
Example: If you place a ×1.8, a ×1.2, and a ×1.2 sync pair on your team, your chances of receiving an Egg will be increased by ×2.2.
