Status Ailment


  • This version of Cosette is arguably one of the worst Lancers in the game. They can be told apart by the actual version having only one set lock of hair sticking up, and the generally more cheerful attitude and appearance, while the lancer version appears to have just woken up and acts as such.
  • While her accuracy stat is similar to her original stats as an engineer, making her the lancer with the greatest accuracy, her potentials may cause frustration - when attacking, if Poor Servicing is triggered, she will not attack, leaving her in danger of being exposed to enemy fire attack. However, like most negative potentials, they are less likely to trigger when Morale is at maximum.
  • Her potential "Committed" is a unique potential that behaves similarly to Double Movement, typically learned from Anthem Elites from the Engineer branch of classes and Fencer Elites from the Armored Tech branch of classes (respectively). With Lancers and Mortarers immunity to landmine damage, and the trick to purposely stepping on them to clear more distance traveled and saving AP, she is capable of traveling farther than any other Lancer unit if this potential triggers.
