1. Recommended Basic Identities
For building a Sinking team, we recommend Yi Sang, Butler Faust, Butler Ishmael, Mariachi Sinclair, and G4 Outis as basic Identities.
In particular, Yi Sang, Faust, and Ishmael are primarily recommended, and Sinclair may be a good alternative if you lack Identities, although his performance may be insufficient as an initial Identity.
N Corp. Outis is not suitable for a Sinking team.
2. Recommended 3★ Identities
Lobotomy Corp. Yi Sang: A Walpurgis Night Identity, recommended if you can obtain it on that date.
Camellia Yi Sang: A good alternative if you don't have Mourning Yi Sang. The 3rd skill Sinking is still good, and it's useful for completing the 10k damage achievement in Walking Fault.
Wild Hithcliff: A highlight Identity with very good performance.
D Rosia: It's good to use Ice Thorns and Snagharpoon together, excluding E.G.O.
Butler Outis: The mansion barrier effect of the 3rd skill is good.
DH Hong Lu: Good for increasing the number of Sinking applications using D Rosia's 1st skill.
DH Mersault: A generally good Identity.
Ebony Stem Ishmael: Inflicts both Tremor and Sinking, but is mainly used for Sinking.
3. Team Building Priorities and Additional Advice
The priority is Mourning Yi Sang, Wild Heathcliff, and D Rosia, and the rest can be freely organized.
Currently, Sinking has become easier to build as the season reward vending machine has been released.
Don't forget to save boxes and madness for Walpurgis Night.
There is no right answer for the team, so it is important to choose an Identity that suits your situation.
