Olwen

Weapon: Flora Guide (+SPD)

Assist: Positional Assist 

Special: Moonbow 

Passive A: Swift Sparrow (2 or 3) / Atk/Spd Push 4 

Passive B: Lull Spd/Res 

Passive C: Panic Smoke / Goad Cavalry 

Sacred Seal: Swift Sparrow 

• Olwen’s combination of 3 movement, 2 range, and Flora Guide can make her a great addition to Aether Raids Defense, particularly in a Cavalry Line whose goals are space control and punishing players that have too many offensive structures to keep frail units from being in enemy range.
• Flora Guide is an excellent inheritable Blue tome that inflicts -5 Spd/Res to enemies within 2 spaces of Olwen. This significantly increases her damage output, as she’ll be able to dish out more damage and more frequently perform follow-up attacks.
• As with Olwen’s other sets, she wants to go all-in on offensive investment. As such, skills that increase her Attack and Speed such as Swift Sparrow and Atk/Spd Push 4 are excellent choices. Note that Atk/Spd Push 4 can potentially be a risky skill to use, as offensive Bolt Towers may drop Olwen’s HP below the ≥ 25% HP condition to receive +7 Atk/Spd increase during combat.
• Lull Spd/Res neutralizes the target’s Speed and Resistance buffs along with inflicting -3 Spd/Res during combat, further bolstering Olwen’s offensive capabilities.
• Panic Smoke can be incredibly obnoxious to deal with if the player uses visible buffs. If their supertank has visible buffs active, applying Panic Smoke will make it significantly more difficult for them to survive the remainder of the enemy attacks, along with potentially making the next Player Phase much more difficult.

Weapon: Dire Thunder

Assist: Positional Assist 

Special: Moonbow 

Passive A: Swift Sparrow (2 or 3) / Death Blow (3 or 4) 

Passive B: Lull Spd/Res 

Passive C: Pulse Smoke / Joint Drive Atk 

Sacred Seal: Swift Sparrow / Death Blow

• Thanks to Dire Thunder, Olwen can provide a unique Aether Raids Offense role to the table: KOing common Red frontliners such as Sothis, Seliph, and Líf without receiving a counterattack like most Mages would have to. She can also 2HKO Eliwood without needing absurd Speed like most other Mages would need, although she needs lots of Attack investment instead.
• As with Olwen’s other sets, Attack and Speed investment from skills such as Swift Sparrow are greatly appreciated to increase her damage and follow-up consistency. While Defense teams rarely use visible buffs, Lull Spd/Res still inflicts -3 Spd/Res to the enemy during combat, making it a strong offensive choice as well.
• Alternatively, players can Attack-stack as high as possible to make Olwen a 2HKO nuke. In this case, Swift Sparrow in both Olwen’s A and S slots are replaced by Death Blow. However, note that Reinhardt does this better since he has higher Attack.
• While Pulse Smoke may seem like a strange choice given that Olwen’s role isn’t Enemy Phase, it allows her supertank partner to use a different C slot such as Atk Smoke or Joint Drive Atk. Alternatively, Olwen herself can use Joint Drive Atk to boost the damage of both herself and her allies.

Weapon: Blárblade+ 

Assist: Positional Assist 

Special: Glimmer 

Passive A: Swift Sparrow (2 or 3) / Fury (3 or 4) / Atk/Spd Push 4

Passive B: Desperation / Lull Spd/Res 

Passive C: Joint Drive Atk / Hone Cavalry / Flexible 

Sacred Seal: Swift Sparrow 

• As with any Blue Mage, Olwen can take advantage of visible buffs to use Blárblade, a tome that grants bonus Attack during combat equal to the sum of Olwen’s visible buffs, to great effect. 
• Olwen’s Cavalry status is especially beneficial, as she can receive +6 Atk/Spd from Hone Cavalry and +6 Def/Res from Fortify Cavalry to easily achieve a whopping +30 damage (24 from the visible buffs and an additional 6 from having +6 Attack). Because she can receive so much bonus damage, Glimmer is Olwen’s strongest Special, increasing her damage by 50% when activated.
• As always, skills that increase Olwen’s Attack and Speed such as Swift Sparrow, Fury, and Atk/Spd Push 4 are fantastic for increasing her damage output. Joint Drive Atk is always a strong option as it grants +4 Attack to Olwen and allies within 2 spaces of her, although a Cavalry-specific skill such as Hone or Fortify Cavalry can substitute if she has Cavalry allies.
• Although Lull Spd/Res is always a strong choice for neutralizing Speed and Resistance buffs and inflicting -3 Spd/Res to the enemy during combat, Desperation is arguably better for PvE content, as it allows Olwen to perform her follow-up attack before the enemy can counterattack if her HP is ≤ 75%. With this in mind, skills that inflict recoil damage such as Fury and Atk/Spd Push 4 may be chosen over Swift Sparrow, although Atk/Spd Push 4’s ≥ 25% HP condition can be a bit awkward to work with in combination with its 5 recoil damage and Desperation’s HP condition.
