Core Analysis is a game mode where you will be able to grind daily resources on stages with restrictions on what type of units you can use.
These stages are made so you have to use a full team of the same “element” (Consolidator, Computator, etc.).
You should do them every day and try to push to level 50 as soon as possible for resource optimization.
The team compositions you see below are what I personally used to clear all stages, but check our tier list and adjust depending on your account.
Note: Team recommendations here are not a one shoe fits all needs. Some stages will require you to change depending on the type of enemy, use this guide as a reference only.
A few notes regarding Computator units:
Last spot can be filled by either Sia or Freyja, depending on your account.
You can use Kaito here since she is REALLY strong, but then your Patricia will lose 120% attack because her passive.
I used triple Ranger to clear most stages and anytime I had issues, I just replaced Erica with Kaito for the extra damage.
Explicators strongest combination it’s Anne paired with Claudia. Rachel is still a beast for both PVE and PVP so no reason to not use her.
Yurizia is the only good option (for now) when it comes to support red units.
Last spot it’s a flex depending on what you have invested, good picks would be Id or Yuna.
