[Fei Performance Summary]
  • •Counter attack attacker with constant evasion rate of 50% └ Activates trigger skill on successful evasion
  • •Trigger skill can be hit repeatedly with CT0 └Be careful of the condition of once per turn
  • •Her upward performance when she continues to succeed in evasion is top class among all characters └On the other hand, when her Revenge Attack does not occur, it is not good
  • •Possesses a guaranteed hit that can ignore pre-emptive defense └Seems to be an essential character in strategy
  • •It is strong that you can aim for an upside with content such as Cosmo Gate that you can try many times.

• If you have a formation that will bring in firepower in a defensive battle, we recommend a formation that uses Fei and Roberta.

• Rosaria, who has high overall firepower and HP +40% Guts, is also excellent, so protecting these three with Hilde's pre-emptive defense is quite powerful.

• For better or worse, it depends on Fei's counters, but on the other hand, depending on the activation of evasion, it has the potential to take revenge on any opponent, so it can be said to be the perfect formation to entrust defensive battles to.

• A party that employs both Fei and Roberta to gain damage through counter attacks.

• Although it depends on the battle environment buff, this party is quite effective against enemies like Demoligis: Beta that Revenge Attack with all-out attacks.

• Since you want to increase the number of times Fei is attacked, it is recommended that you do not attach pre-emptive defense to the defender and place Fei in the vanguard position.

• It is recommended that the Assassin organization be centered around Bunnygirl Charlotte, with Kyra as the hidden personnel and Haydee as the tank.

• If the enemy has high firepower or attacks frequently on all targets, it would be a good idea to change Kyra to Emilly or Asherah: Waltz of Starlight.

• The way you fight will change greatly depending on whether Fei has a counter or not, so be careful when operating it manually.

• A formation that combines Fei, which increases evasion rate by 50%, and Amora, which can repeatedly decrease accuracy rate by 30%.

• In order to inevitably focus your attacks on Fei, use Gwen, who has a stealth ability that cannot be canceled, and hit as many counters as possible.

• I'm a little worried about Fei's durability, so I recommend setting her hard potential to XX2 so she can self-heal.

• Asherah: Waltz of Starlight is also recommended for the Carmen: Eternal Promise slot, but be careful as the overall firepower is likely to decrease when you form a defender who absorbs enemy attacks.

Fei's Rescue Journey Training & Recommended Arcana

Recommended Arcana Deck: Fei organization

[Key Arcana Deck & Rescue Journey Points]
  • •Training that prioritizes strength is OK
  • •There is an attack debuff, so it would be nice to be able to concentrate, but it's not enough to prioritize it └I only step on it for Potential Points.
  • •If you use Fei Arcana, you don't need Crit Rate, so potential Crit DMG, attack, and speed are recommended.
