|With Celica's high Spd, she can utilize a Firesweep Sword+ pretty well, which also pairs perfectly with her Double Lion skill.
Weapon: Firesweep S+ is Celica's weapon of choice. It denies the opponent and the user from counterattacking, making it a purely player phase weapon. While this means Celica has no enemy phase presence at all, it makes her player phase presence much more formidable.
Assist: Reposition is a good Assist in general to use. Its uses are versatile, as it can either help bring an ally closer to the fray, or bring an ally out of danger.
Special: Moonbow is Celica's Special. It pierces through her foe's Def, helping her break through sturdier opponents. With her B skill, Seal, and enough Spd, she can potentially activate this twice in her first round of combat, which is all but certain to destroy her foe.
A Passive: Death Blow 4 is Celica's A skill. It grants her an impressive +8 Atk when initiating combat, which is perfect, as she'll only want to initiate combat most of the time anyway.
B Passive: Double Lion is Celica's B skill. When she's at full health, she will strike twice consecutively, just as if she was wielding a Brave Sword+. After combat, she'll suffer 1 HP of damage, knocking her out of this effect. If Celica wants to use Double Lion throughout the map, she needs some form of healing, either through her Special or through the support of an ally. This effect is incredibly powerful, as Celica also has very good Spd, allowing her to potentially perform quadruple strikes against her opponents if they are slow enough.
C Passive: Atk Tactic 3 is an option for Celica's C skill. It grants +6 Atk to all nearby allies as long as the team composition requirements are met, namely that there cannot be more than two of a movement type on the team. However, this skill slot is flexible, depending on player preference.
Sacred Seal: Flashing Blade 3 is Celica's Seal. If she outspeeds her foe, she can get an extra Special charge with her attacks. This means that Celica should be able to strike once and charge her Special immediately, activating it on the second strike. With Double Lion, she can potentially perform a quadruple strike, and the process repeats: she'll strike again, and then her final strike will have Moonbow charged.
