Synchro Device

In GODDESS OF VICTORY:NIKKE You can use up to five Nikkes to form a team that you can deploy to destroy Raptures and complete objectives and missions. However, improving them will require too many resources. Because of this, it’s optimal to focus on five Nikkes or your main gear first before leveling up. But in case you want to use other Nikkes outside of your equipment, you can use the Synchro Device. Synchro Device is a device that you can use to synchronize the level of one Nikke with another, so you won’t have to use resources instead. The Synchro device automatically selects five Nikkes of the highest level, and the lowest among these five will determine the Synchro level. However, upgrading to the lowest level will also automatically increase the sync level.

After doing so, you will be given five spaces where you can place a maximum of five Nikkes on those spaces. Nikkes placed in these slots will automatically gain the same level as the sync level until they are removed. The levels of the synchronized Nikkes will depend on him and cannot be updated while he is assigned to the slot.
At first you can only include five Nikkes in the slot, however you will be able to get 5 additional slots with certain missions and if you plan to add another slot, you must first spend 500 free or paid gems.

The Nikkes in the slot can be removed or replaced. This will return them to their original level and the slot will go on cooldown for 4 hours. During this time, you will not be able to fill it with a Nikke.

Advanced Sync

When 5 Nikkes reach level 200, Advanced Sync is unlocked. Each level consumes a large number of battle cores; 10,000 per level. Leveling up advanced sync is the same as leveling up all units currently on the sync device. There is also a limit to how high you can level your units’ advanced synchronization. The formula to increase said level is the following:

1. 1 LB = 1.33 levels
2. 1 Unique character = 1 level
3. Cores do not count
4. SSR’s and SR’s are included in the formula
