Adrift Corrin (F)

Preferred IV: +ATK or +SPD or +RES / -HP

• +ATK and +SPD both boost Corrin’s damage output, which is very important for taking out Aether Raids units before they get refreshed. However, +RES can be chosen to tank prevalent magical units such as Ophelia and Brave Veronica better. While -HP is Corrin’s best Flaw, this set generally shouldn’t be used unless Corrin is heavily merged, as her efficiency in Aether Raids greatly decreases without stat increases from merges.

Weapon: Lightning Breath+ (+SPD or +RES)

• Being able to counterattack against ranged units is valuable, especially in Aether Raids due to the high amount of ranged units on Aether Raids defense teams. +SPD can be chosen to secure a follow-up attack, while +RES can be chosen to increase Corrin’s magical bulk.

Assist: Reposition / Flexible 

Special: Noontime / Sol

• Aether Raids tanks usually need sustainability via their Special, so Noontime or Sol are the best options for Corrin. Note that due to Lightning Breath increasing Special cooldown by one, Corrin needs Flashing Blade to have an opportunity to activate Noontime in one combat or a Breath A slot to have an opportunity to activate Noontime or Sol in one combat. 

Passive A: Bonus Doubler / Fierce Breath / Steady Breath / Warding Breath 

• A buff-bot, Legendary Azura or otherwise, almost always compliments an Aether Raids tank. As such, Bonus Doubler is a fantastic option for Corrin, as she can receive up to +14 to all stats with the right buffs.

• Any Breath skill can serve as a great alternative, as they provide Corrin with minor stat buffs and +1 Special charge per attack during combat. Utilizing a Breath skill allows Corrin to activate any 2 or 3 Special cooldown in one combat, assuming she performs a follow-up attack and her enemy lacks a Guard effect.

Passive B: Null C-Disrupt / Null Follow-Up / Quick Riposte / Wrath

• Sweep effects and weapons are very common for Aether Raids defense teams, making Null C-Disrupt a good option for Corrin. This increases her damage output, since she will be able to counterattack against any enemy.

• Null Follow-Up is a great alternative, since Corrin relies on performing a follow-up attack to dish out high damage. Corrin is also reliant on performing a follow-up attack for sustainability via her Special.

• Quick Riposte can be used to guarantee a follow-up attack against extremely fast enemies or follow-up nullifying enemies, although Corrin’s Speed is already very high. Noontime and Sol help Corrin stay in Quick Riposte range.

• Corrin’s mediocre Attack can be partially mitigated via Wrath, as it increases the damage of her Special. Note that increasing Noontime and Sol’s damage increases the amount she heals from them, which could push Corrin out of Wrath range.

Passive C: Pulse Smoke / Atk Smoke 

• Infantry Pulse and Ostia’s Pulse defense teams are extremely prevalent in Aether Raids. Corrin usually will fail to take many Specials even with Noontime or Sol, so preventing them from activating altogether via Pulse Smoke greatly increases her survivability.

• If Pulse Smoke is unavailable, Atk Smoke is the best alternative. Debuffing the enemies’ Attack increases her survivability.

Sacred Seal: Fierce Stance / Flashing Blade

• Since Corrin’s Speed and defenses are so high already, Corrin can focus on increasing her Attack on Enemy Phase with Fierce Stance. Doing so helps her take advantage of her amazing Speed more efficiently.

• If utilizing Bonus Doubler, Flashing Blade is a fantastic alternative. Assuming Corrin performs a follow-up attack and the enemy has no Guard effect, Corrin will be activating Noontime every combat.

Preferred IV: +ATK or +SPD / -HP

• +ATK and +SPD are both great Assets for Corrin. +ATK helps Corrin take full advantage of any follow-up attacks, while +SPD helps secure that those follow-up attacks will occur. -HP is chosen as Corrin’s Flaw since lower HP helps Corrin activate Wrath and Vantage sooner.

Weapon: Draconic Rage

• Draconic Rage’s activation requirement is usually easy to achieve for an Enemy Phase set since Corrin will often be close to her allies. -1 Special cooldown and +5 Attack and Speed greatly benefits Corrin’s damage output via faster Specials and higher and more consistent damage.

Assist: Reposition / Flexible

Special: Luna / Blue Flame / Bonfire / Sol

• 3 Special cooldowns work great with Corrin’s high Speed and Draconic Rage’s Special cooldown acceleration. While Luna is generally preferred to help Corrin score KOs on especially tanky enemies, Blue Flame and Bonfire deal more consistent damage than Luna. Sol can be used instead to give Corrin sustainability.

Passive A: Distant Counter / Atk/Spd Form / Atk/Spd Bond / Brazen Atk/Spd (3 or 4)

• For an Enemy Phase set, Corrin wants to counterattack as many enemies as possible to put her Attack and Specials to use. Distant Counter is Corrin’s only option of doing so if she utilizes Draconic Rage.

• Atk/Spd Form has fantastic synergy with Draconic Rage, as they both activate depending on the number of allies within 2 spaces of Corrin. In an optimal situation, Corrin will be gaining a whopping 12 Attack and Speed from Draconic Rage and Atk/Spd Form alone.

• A more budget-friendly option that still works well is Atk/Spd Bond. Corrin will usually be close to her allies, so Atk/Spd Bond synergizes with her Enemy Phase skills and role.

• Brazen Atk/Spd is a great alternative that shifts Corrin’s focus from surviving many hits to OHKOing with Vantage and stacking Attack buffs. Note that Corrin will not be able to counter against ranged enemies or enemies with Sweep effects, so its effectiveness is limited.

Passive B: Wrath / Vantage / Null C-Disrupt

• Wrath can help make up for Corrin’s mediocre Attack by adding 10 true damage to her Special damage. Combining Wrath with Flashing Blade and Sol can make Corrin’s sustainability very solid.

• If focusing on OHKOing, Vantage is Corrin’s best option so she doesn’t have to worry as much about her bulk and sustainability. 

• Even with Distant Counter, Corrin’s counterattack(s) can still be prevented via Sweep effects. Null C-Disrupt ensures that Corrin will counterattack against all enemies.

Passive C: Res Smoke / Atk Smoke / Flexible

• Res Smoke helps Corrin and her magical allies deal more damage to nearby enemies.

• If focusing on Corrin’s survivability, Atk Smoke can be utilized instead.

• Aside from Res Smoke and Atk Smoke, Corrin’s C slot is flexible. She can change it to whatever the player believes best fits her team and allies.

Sacred Seal: Fierce Stance / Atk/Spd Bond / Atk/Def Bond / Brazen Atk/Spd / Brazen Atk/Def

• Fierce Stance is the most consistent way for Corrin to increase her Attack on Enemy Phase, as it doesn’t require adjacent allies or an HP threshold.

• Atk/Spd Bond and Atk/Def Bond are strong alternatives that synergize well with Corrin’s Enemy Phase role.

• Since Corrin’s B slot usually involves an HP threshold, Brazens can be used thanks to HP thresholds of their own. Doing so leaves Corrin’s initial combat slightly weaker than her combat at ≤80% HP.
