Summer Elincia

Weapon: Whitecap Bow+ (+Spd)

Assist: Positional Assist 

Special: Moonbow / Ruptured Sky 

Passive A: Atk/Spd Boosting A Slot / Heavy Blade 4

Passive B: S/D Far Trace / Aerobatics / Flier Formation

Passive C: Atk/Spd Menace / Spd/Def Rein / Spd Smoke

Sacred Seal: Atk/Spd Solo / Blade Session / Heavy Blade 

• Elincia’s respectable 36/40 offenses naturally lend her well to a Player Phase, damage-focused set. Her native Whitecap Bow grants +5 Atk/Spd and allows her to attack twice on initiation if her Spd is ≥ 10 higher than the enemy’s Spd, so Spd investment not only helps her activate this Brave effect, but also aids in performing follow-ups.
• Low-cooldown Specials that augment Elincia’s damage work best, making Moonbow and Ruptured Sky her strongest Special choices. If no Guard effect is active, Elincia has Heavy Blade in her A or S slot, and she activates Whitecap Bow’s Brave effect, she can activate these Specials on her second attack, which significantly increases her 2HKO consistency. 
• If not using the aforementioned Heavy Blade 4, Atk/Spd Boosting A slots are ideal to maximize Elincia’s damage output and follow-up and Brave effect consistency; in particular, Atk/Spd Catch 4 synergizes well with Atk/Spd Menace as her C slot. The latter grants Elincia +6 Atk/Spd and inflicts -6 Atk/Spd on the nearest enemies within four spaces at the start of the turn, while the former grants Elincia +7 Atk/Spd during combat if the enemy’s HP = 100% or if the enemy has visible debuffs (such as those inflicted by Atk/Spd Menace) and +9 Atk/Spd if both conditions are met. Alternative C slots include Spd/Def Rein, which simply inflicts -4 Spd/Def on enemies within two spaces during combat, and Spd Smoke, which inflicts -7 Spd on enemies within two spaces of the target after combat.
• S/D Far Trace inflicts -3 Spd/Def on the enemy during combat, making it Elincia’s best (and pretty much only) B slot for damage output. However, its Canto effect is difficult to make use of because Elincia only has 2 movement, so if greater mobility is desired over slightly better combat, Aerobatics or Flier Formation can be chosen instead depending on Elincia’s allies.
• If not using the aforementioned Heavy Blade Sacred Seal, those that boost Elincia’s Atk/Spd are her best options. Atk/Spd Solo simply grants +6 Atk/Spd during combat if Elincia is not adjacent to an ally (note that this is anti-synergistic with Aerobatics and Flier Formation, in which case Atk/Spd Bond can be used for +5 Atk/Spd during combat when Elincia is adjacent to an ally), while Blade Session grants +3, +6, or +9 Atk/Spd on initiation if zero, one, or at least two allies have moved respectively.

Weapon: Whitecap Bow+ (+Spd)

Assist: Dual Rally+ / Rally Up+ 

Special: 500 SP Specials

Passive A: B Duel Flying 4

Passive B: S/D Far Trace / Watersweep 

Passive C: Atk/Spd Menace / Spd Smoke 4

Sacred Seal: Atk/Spd Solo / Blade Session / Heavy Blade 

• Being a relatively decent unit that is obtainable through Heroic Grails, Elincia is a strong choice for max-investment Arena. This set focuses on maximizing her score while decreasing her usability as little as possible; however, because Elincia lacks access to a 300 SP B slot and a personal (400 SP) weapon, all of her skills need to cost the maximum SP cost to hit the 2300-2400 SP bin of Coliseum scoring.
• Elincia’s native Whitecap Bow is her strongest weapon, as +5 Atk/Spd and a conditional Brave effect significantly improve her damage output.
• 500 SP Special options include Deadeye, Ruptured Sky, Aether, and Blue Flame. If using Heavy Blade in Elincia’s Sacred Seal, she may be able to activate lower-cooldown Specials despite the ubiquity of Special-slowing effects in Arena, making Ruptured Sky, Deadeye, and Blue Flame preferred if available. Deadeye is particularly helpful thanks to its doubled damage and neutralization of damage reduction effects.
• B Duel Flying 4 is a necessity, as it treats Elincia’s BST as if it were higher for Coliseum scoring purposes.
• S/D Far Trace inflicts -3 Spd/Def on the enemy during combat, improving Elincia’s damage output; however, its Canto effect is difficult to use due to Elincia’s 2 movement. Watersweep is a niche, but very strong alternative; preventing counterattacks against the myriad of magical Far Save enemies can be well worth the penalty of being unable to perform a follow-up, which is alleviated by Whitecap Bow’s conditional Brave effect anyway.
• Atk/Spd Menace and Spd Smoke 4 are Elincia’s best C slots, with the former granting +6 Atk/Spd to her and inflicting -6 Atk/Spd on the closest enemies within four spaces and the latter inflicting -7 Spd on enemies within two spaces after combat in addition to granting Elincia Spd-based damage reduction.
• If not using the aforementioned Heavy Blade and preferring to invest into Elincia’s offenses instead, Atk/Spd Solo and Blade Session are her ideal choices. Atk/Spd Solo grants +6 Atk/Spd during combat if Elincia is not adjacent to an ally, while Blade Session grants +3, +6, or +9 Atk/Spd on initiation if zero, one, or at least two allies have moved respectively.
