IV Sets

Key stats worth increasing through nature if possible.
Complementary stats that matter, but not to the point of picking them over key stats for nature increase.
Relatively worthless stat that can safely be decreased through nature.


  • +ATK: With a pathetic base 26 Attack, Olwen greatly appreciates an Attack Superasset to increase it to a passable 30. Doing so boosts her damage output considerably, especially if using Dire Thunder.
  • +SPD: A Speed Asset increases Olwen’s Speed from 34 to a fantastic 37, increasing her ability to perform follow-up attacks. If utilizing Blárblade, Olwen will want a Speed Asset over an Attack Asset because her damage can be increased via visible buffs.


  • RES: Olwen’s Resistance sits at 30, which allows her to utilize Ploys decently. If Olwen is not using Ploys, -RES is an acceptable Flaw, as decreasing her magical bulk from 63 to 60 is usually insignificant.


  • -HP: Although an HP Flaw decreases Olwen’s physical and magical bulk, doing so hardly affects her defensive capabilities. Note that with Fury 4 and an HP Flaw, a low-merge Olwen will activate Desperation after one combat. 
  • -DEF: Olwen’s physical bulk already sits at an awful 53, so lowering it to 50 with a Defense Flaw negligibly impacts her performance.

Skill Sets

Raining Holy Swords on her Enemies (Blárblade)

Build by
Blárblade+ A Swift Sparrow (2 or 3)
Alternate: Brazen Atk/Spd (3 or 4)
Alternate: Ardent Sacrifice
B Desperation 3
Alternate: Moonbow
C Res Ploy 3
Alternate: Hone Cavalry
IVsSSturdy Blow 2
Alternate: Darting Blow 3

Show Explanation/Analysis

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

  • +SPD is Olwen’s best Asset when wielding Blarblade, as it secures more follow-up attacks. Olwen can stack her Attack thanks to Blarblade’s effect far greater than her Speed, so a Speed Asset helps her make the most of it. -DEF and -HP are her best Flaws for this set, since lowering her bulk hardly affects her combat.

Weapon: Blárblade+ 

  • Olwen’s awful Attack can be helped by Blárblade, which adds the sum of Olwen’s visible buffs to her Attack. 

Assist: Reposition / Ardent Sacrifice / Flexible 

  • While Reposition is good for movement, Ardent Sacrifice is an alternative to activate both Brazen Atk/Spd 4 and Desperation. Of course, Olwen’s Assist is flexible depending on her allies.

Special: Glimmer / Moonbow

  • Like most Blade units, Olwen’s best Special is arguably Glimmer because it scales based on the Attack increase provided by Olwen’s visible buffs. 

  • Moonbow is a viable alternative to help secure KOs on high-Resistance units or units with Dull Ranged.

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

  • Granting Olwen +6 Attack and +7 Speed, Swift Sparrow 3 greatly increases her raw damage and ability to perform follow-ups. Swift Sparrow 2 works fine, although the Attack and Speed buffs will be lower than Brazen Atk/Spd 3 or Atk/Spd Solo.

  • Compared to Swift Sparrow 3, Brazen Atk/Spd 4 grants Olwen 3 more Attack and Speed when activated. It may be worthwhile to use Brazen Atk/Spd 4 and activate it via Ardent Sacrifice or surviving an enemy attack, since Olwen appreciates as high offensive buffs as possible. Compared to Swift Sparrow 2, Brazen Atk/Spd 3 also grants Olwen 3 more Attack and Speed, so it’s a great budget alternative.

  • Atk/Spd Solo and Fury 3/4, while not granting as much Attack and Speed, are strong alternatives. The latter makes Olwen’s Enemy Phase capabilities passable, especially since she’ll have a solid 66/67 magical bulk at neutral.

Passive B: Desperation 

  • Even with Blárblade, Olwen struggles to OHKO her enemies, and her ability to survive a counterattack is inconsistent. Desperation allows Olwen to utilize her great Speed to perform a follow-up attack before receiving a counterattack, greatly increasing her survivability and lethality.

Passive C: Res Ploy / Hone Cavalry / Flexible

  • Olwen’s 30 Resistance helps her Ploy a decent range of enemies, especially if combined with Fury 3 or 4. Res Ploy is particularly helpful, as Olwen generally has more trouble with her raw damage than performing a follow-up attack.

  • If using Olwen on a Cavalry team, Hone Cavalry is a great alternative. Otherwise, Olwen’s C slot is flexible and can change depending on her allies.

Sacred Seal: Sturdy Blow / Darting Blow 

  • Sturdy Blow increases Olwen’s Attack and Defense by 4, benefiting her damage output and ability to survive physical counterattacks.

  • Darting Blow is a great alternative if the player is concerned about her ability to perform a follow-up attack even with Speed buffs from her A slot and allies.

Unique from her Brother (Dire Thunder)

Alternate: Ardent Sacrifice
B Desperation 3
Alternate: Chill Res 3
Alternate: Luna
C Res Ploy 3
Alternate: Hone Cavalry
IVsSSturdy Blow 2
Alternate: Darting Blow 3

Show Explanation/Analysis

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

  • +ATK and +SPD are fantastic Assets for this set, with the former raising her raw damage and the latter increasing her chances of quadrupling. -DEF and -HP work fine as Flaws, as lowering Olwen’s bulk barely matters for her performance.

Weapon: Dire Thunder

  • Dire Thunder is Olwen’s only option for a set focusing on quadrupling. 

Assist: Reposition / Ardent Sacrifice / Flexible 

  • While Reposition is the usual go-to Assist skill, Ardent Sacrifice can be used to activate Brazen Atk/Spd 4 and Desperation instead.

Special: Moonbow / Luna

  • Olwen appreciates Moonbow or Luna, as both help her damage output against high-Resistance enemies that can blow off her raw damage.

Passive A: Swift Sparrow (2 or 3) / Brazen Atk/Spd (3 or 4) / Atk/Spd Solo / Fury (3 or 4) / Life and Death

  • Swift Sparrow 3 is chosen because Olwen should always be initiating combat. Gaining +6 Attack and +7 Speed greatly helps Olwen’s damage output via increasing her raw damage and raising her chances of performing a follow-up attack. Swift Sparrow 2 is a good budget alternative, since it still grants Olwen +4 Attack and +4 Speed on initiation. Note that this grants less Attack and Speed than Brazen Atk/Spd 3 and Life and Death.

  • If willing to purposely drop Olwen’s HP below 80% via surviving an enemy attack or using Ardent Sacrifice, Brazen Atk/Spd 4 is an amazing alternative that increases her Attack and Speed by 3 more than Swift Sparrow 3. Brazen Atk/Spd 3 works as well, since it still provides more Attack and/or Speed than Swift Sparrow 2 and 3, Atk/Spd Solo, and Life and Death.

  • Atk/Spd Solo and Fury 3/4 are other alternatives that increase her offensive capabilities. The latter can help Olwen activate Desperation, which is vital for a quadrupling set.

  • A good and easily obtained alternative is Life and Death. +5 Attack and +5 Speed is a lot of extra offensive power, and Olwen should not need to tank hits very often. 

Passive B: Desperation / Chill Res

  • Since Olwen’s Attack can sometimes be too low to 2HKO, this set focuses on performing 4 straight attacks by increasing both her Attack and Speed and activating Desperation. Landing 4 consecutive attacks rather than 2 helps Olwen secure more KOs.

  • Chill Res works well since it can help Olwen and her magical allies KO high-Resistance enemies. 

Passive C: Res Ploy / Hone Cavalry / Flexible

  • Olwen’s decent 30 Resistance can be increased via Fury 3 or 4, allowing her to utilize Ploys well. Res Ploy is especially useful, since it increases the damage output of both herself and her magical allies, though any Ploy skill can be used.

  • Hone Cavalry works as an alternative if using Olwen for a Cavalry team. Of course, her C slot is flexible, so the player can change it depending on her allies.

Sacred Seal: Sturdy Blow / Darting Blow

  • Sturdy Blow increases her raw damage and chances of surviving a physical counterattack if necessary.

  • Since Olwen’s ability to quadruple is shaky even after Speed buffs due to Dire Thunder’s -5 Speed penalty, Darting Blow can be used to ensure as many follow-up attacks as possible.


Entering as our first character from Thracia 776 along with her brother Reinhardt, Olwen joins as a blue mage cavalier wielding the divine Dire Thunder! Sadly, unlike her brother, Olwen struggles to find a place or niche in the metagame due to her poor statline.

Olwen’s high Speed of 34 and decent Resistance of 30 are her only good stats. 34 HP and 20 Defense leaves Olwen incredibly prone to being OHKO’d by physical units, which wouldn’t be so bad if she had more than 26 Attack. 26 Attack is especially bad when taking her personal weapon, Dire Thunder, into consideration. Dire Thunder is a 9-might weapon that grants Olwen an automatic second attack if she initiates, which can turn into 4 attacks if Olwen would naturally perform a follow-up. Olwen’s awful Attack forces her to stack lots of Attack buffs to reach the same Attack as her peers, though she can partially compensate for this via Blárblade, which increases her Attack based on her visible buffs. Olwen relies on lots of Attack and Speed buffs if wanting to utilize Dire Thunder to quadruple, as 2HKOing simply isn’t viable for Olwen in most cases. This is further amplified considering her brother is capable of 2HKOing much more consistently than Olwen because of his higher Attack. In terms of defensive capabilities, Olwen’s physical bulk of 53 is pathetic, although her magical bulk of 63 is solid thanks to her 30 Resistance. 30 Resistance is also good enough to use Ploys fairly effectively, allowing both herself and her magical allies to dish out more damage or survive more enemy attacks.

Being a cavalry unit both benefits and harms Olwen. As for positives, 3-movement and access to Horse buffs is incredibly valuable, since both can bolster Olwen’s offensive capabilities (especially if using Blárblade). As for negatives, trenches and forests arguably mitigate Olwen’s 3-movement. Also, while her bulk isn’t impressive to begin with, cavalry-effective weapons will likely spell an untimely demise for Olwen.

Unfortunately, Olwen hasn’t been very good since her release. Her low Attack dramatically hampers her viability, and as time has gone on, more blue mage cavaliers have been released that completely outshine Olwen. However, with enough hard work and investment, Olwen can still become a decent unit that can pull her weight.


Good Speed

Olwen’s solid 34 Speed allows her to utilize both a Blárblade set and a Dire Thunder set focused on quadrupling. It also helps Olwen to survive any attacks on Enemy Phase, since her opponent usually won’t perform a follow-up attack.

Cavalry strengths

3 movement and access to Cavalry buffs greatly benefit Olwen, with the former granting Olwen greater positioning capabilities and the latter being especially useful if utilizing Blarblade.


Horrendous Attack

Olwen’s viability plummets because of her terrible 26 Attack. While it can be increased and partially mitigated with the help of Blárblade and Attack buffs, her damage output remains lacking compared to her competition.

Terrible physical bulk

With 34 HP and 20 Defense, Olwen is very susceptible to being OHKO’d by physical enemies on counterattacks or Enemy Phase. This forces her to use Desperation as her B slot unless focusing on 2HKOing with Dire Thunder.

Immense competition

In terms of competition, Olwen has a lot of it. L’Arachel, Spring Catria, Groom Pent, Reinhardt, Valentine’s Soren, the list goes on... and they all outclass Olwen thanks to their higher Attack. While L'Arachel and Reinhardt’s Speed stats are notably lower than Olwen’s, their availability as a 3-4* units allows players to merge them much easier than Olwen. Reinhardt’s 2HKO niche is also far better than Olwen’s Blárblade and quadrupling niche, since it’s much more reliable.

Cavalry shortcomings

Trenches, forests, and cavalry-effective weapons plague all cavaliers, and Olwen is no exception. Reduced movement greatly hurts Olwen’s offensive capabilities, and she may have trouble reaching some of her enemies.
