The Flow family of B slots is extremely powerful, granting Fliers offensive Null Follow-Up and an additional effect depending on which is chosen. Atk/Spd Boosting A slots increase Catria’s raw damage, follow-up consistency, and bonus damage from Astra Blade all in one fell swoop, making them ideal choices. Since Astra Blade has no cooldown acceleration or additional Special charge, low cooldown Specials such as Moonbow and Glimmer work best while they have less impactful damage increases, they activate more frequently, which is generally a beneficial tradeoff given the ubiquity of Guard effects. Vantage nuking aside, Catria is ill-suited for Enemy Phase combat, so she can focus primarily on making her Player Phase as strong as possible. Sacred Seal: Atk/Spd Solo / Heavy Blade / Blade Session Passive B: Flow Skills / Dive-Bomb / S/D Near Trace However, if Catria is unable to reach this HP threshold before her first combat, then Fierce Stance may be better, which grants +6 Atk when defending rather than on an HP condition. Atk-increasing Brazen Sacred Seals such as Brazen Atk/Spd and Brazen Atk/Def increase Catria’s Atk by 7 when she has ≤ 80% HP, making them the best options for maximizing damage output. Joint Drive Atk works as well, simply granting Catria +4 Atk if she is within two spaces of an ally. Which is chosen generally doesn’t matter, though Spd/Def Rein is most notable since Spd control helps cut into Spd-based damage reduction and helps Catria perform/avoid follow-up attacks if necessary (for example, she can fall back on performing/avoiding a follow-up attack if she fails to OHKO). Def-reducing Rein skills such as Atk/Def Rein and Spd/Def Rein maximize the gap between Catria’s Atk and the enemy’s Def by inflicting -4 Def on enemies within two spaces, making them ideal choices. Any Distant Countering A slot that allows Catria to counterattack against all weapon types works fine, though Distant Storm is notably stronger thanks to its +5 Atk during combat and 5 recoil damage helping Catria reach Vantage range. Both Moonbow and Miracle are strong Special choices, with the former ignoring 30% of the enemy’s Def for some extra punch and the latter allowing Catria to survive a lethal attack if her HP is > 1.
While 1 damage isn’t nearly enough to drop Catria to 75% HP, she can use Ardent Sacrifice to decrease her HP in increments of 10 until she reaches ≤ 75% HP. Since Catria’s bulk is on the lower side, she may have trouble reaching this HP threshold without being outright KO’d as such, one of her best teammates is Winter Bernadetta, whose weapon inflicts 1 damage on herself and allies within two spaces at the start of the turn if her HP is 100%.This is better showcased on Enemy Phase in combination with Vantage, a B slot that allows Catria to counterattack before the enemy attacks if her HP is ≤ 75%. With Atk investment effectively having +50% value on Catria, she can focus solely on maximizing her OHKO capabilities. Astra Blade increases Catria’s damage by 50% of the gap between her Atk and the enemy’s Def.Sacred Seal: Atk-increasing Brazen Skills / Fierce Stance Passive C: Def-reducing Rein Skills / Joint Drive Atk Passive A: Distant Storm / Distant Counter
