Brave Celica

Weapon: Royal Sword (+Eff) / Royal Sword (+SPD)

Assist: Positional Assist 

Special: Galeforce

Passive A: Death Blow / Swift Sparrow / ATK/SPD Solo

Passive B: Double Lion / Wings of Mercy

Passive C: Time’s Pulse  / Preference

Sacred Seal: Quickened Pulse / Death Blow / Swift Sparrow

• Celica’s base kit along with the refine provides a good reference build for her to be a Galeforce oriented player phase unit.
• With the in-built acceleration of Royal Sword, the cooldown of Galeforce will drop to 1 if Celica takes down the opponent in 2 hits using Double Lion. The extra refine effect will result in 1 more charge, which leads to Galeforce activation.
• The primary goal of this build is to take her foes down in 2 hits. Stacking as much as attack as possible does increase the damage output, however could lead to some issues if she takes the foe out in a single hit. It is recommended for players to run other forms of cooldown acceleration from other units, such as from Infantry Pulse, Velouria’s Wolfpup Fang and Rafiel’s Groom’s Wing. For a self-sufficient build, players can give Celica Time’s Pulse and Quickened Pulse, which will enable Celica to charge Galeforce in a single strike.
• Due to Celica’s high speed, it is also possible to aim for a follow-up attack. While the damage ceiling is higher, Celica does not gain much from the follow-ups in terms of charging up Galeforce. For such a build, one should replace Death Blow with Swift Sparrow or ATK SPD Solo.

Weapon: Royal Sword (+Eff)

Assist: Positional Assist / Rally Assist

Special: Sol / Galeforce / Aegis

Passive A: Distant Counter

Passive B: Spurn / Null Follow-Up

Passive C: Pulse Smoke / Time's Pulse / ATK Smoke

Sacred Seal: Quick Riposte / SPD/RES Solo

• This build focuses around the defensive nature of Royal Sword’s unique refinement. Celica’s weapon provides 5 to all stats, 7 HP and -1 cooldown after combat similar to a combination of Mystic Boost and Special Spiral. When paired with Time’s Pulse, Royal Sword becomes effectively a weapon similar to Slaying Edge, which is definitely useful for her to charge higher cooldown specials. Players are recommended to run other form of special mitigation, such as those from Even Pulse Tie and Odd Pulse Tie, otherwise Pulse Smoke is probably a safer pick.
• The choice of specials is dependent on her support. If a player chooses to run Brave Lucina as a support, due to the extra on-damage cooldown acceleration provided by Geirskogul, Sol is a good option. Otherwise, one can either use a lower cooldown healing special such as Noontime, or consider relying on her on-hit acceleration that Royal Sword comes with. The latter opens up the use of defensive specials such as Aegis, or offensive ones such as Luna. Players need to keep in mind that Royal Sword will need at least 1 ally within 2 spaces to be active in the enemy phase. Alternatively, using Galeforce leverages on Brave Celica's on-hit special acceleration well and has huge payoff as she can take out 2 foes in a single player phase. 
• Brave Celica is spoilt for choice in terms of her Passive B. Due to her high speed, both Null Follow-up and Spurn are legitimate options for Celica to consider depending on a user’s taste and preferences.
• If a player does not run Null Follow-Up, it might also be worthwhile for Celica to run Quick Riposte as the Sacred Seal to be capable of following up from any form of follow-up negation such as Sturdy Impact and Brave Roy’s Blazing Durandal.

Preferred IV:+ATK / -RES

Weapon: Armorsmasher+ (+Atk)

Assist: Reposition

Special: Glimmer

Passive A: Death Blow

Passive B: Double Lion

Passive C: Joint Drive ATK / Flexible

Sacred Seal: Death Blow / Flashing Blade / Heavy Blade / Quickened Pulse

• For players looking to use Celica in Arena Assault, an Armorsmasher+ can be a great investment to counter one of the most common class you'll encounter. +ATK is the recommended boon without question, as few armored heroes will manage to avoid Celica's four attacks. Nonetheless, offense is the best defense in this case: Celica will want to maximise her attack in order to KO enemy armored heroes within two blows, otherwise she risks a retaliation.
• As the objective of the build is to delete armors in 2 hits, the only stat she cares about is ATK to allow effective damage to scale to take down any armored foes. Hence, the build Joint Drive ATK and stacking Death Blow in both her Passive A and Sacred Seal to maximise that scaling. Glimmer is also chosen as it also stacks with effective damage.
• Though Celica can almost singlehandedly destroy armored teams with this build, it's not perfect by any means. Without her Royal Sword, Double Lion is still a problem, as Celica will be reliant on support to keep the powerful effect active. Without it, she risks taking heavy damage against armored heroes that she fails to defeat in a single blow, which can spell defeat. Additionally, Celica will find herself far weaker than usual if she doesn't have any armored opponents to face. Against dragon heroes or other classes, Celica will struggle more considerably than she would with a more flexible offensive build. For such situations, relying on Glimmer activation is not the worst idea possible.
