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.
  • Olwen's abysmal atk and reasonably high spd, combined with the fact that she normally won't be used without heavy Horse Emblem support, make +atk and +spd the only interesting stats to nature-hone for.
  • Olwen's res is actually decent. Ideally, dump def or hp.

Blárblade+ A Fury 3
Reposition B Desperation 3
Dragon Fang C Ward Cavalry

Show Explanation/Analysis
  • Preferred nature: +atk/-hp or +spd/-hp
  • Weapon: Blarblade+ / Blarblade
  • Assist: Reposition / Draw Back / Ardent Sacrifice
  • Special: Dragon Fang / Draconic Aura / Moonbow
  • A slot: Fury 3 / Life and Death 3
  • B slot: Desperation 3
  • C slot: Ward Cavalry

Basically Linde on a horse. Under full Horse Emblem buff (i.e. Hone+Fortify Cavalry), Blarblade+ provides 37 atk overall (13 base + 24 blade buff), plus six additional points from the atk buff itself. This will make +atk Olwen reach 73 (not accounting for Fury / Life and Death), which is enough to nuke nearly everything in existence (you're expecting to hit twice).

Life and Death provides the absolute maximum level of destruction Olwen can produce (she needs the speed buff, which excludes Defiant Atk and Death Blow), which is 74 (78 if +atk). However, Fury makes it much easier to boot Desperation and makes Olwen capable of tanking a couple hits, which is not negligible for real-life situations.

A few spd values to keep in mind:

  • +atk, Life and Death reaches 39 spd - 45 with Hone Cavalry.
  • +atk, Fury reaches 37 spd - 43 with Hone Cavalry.
  • +spd, Life and Death reaches 42 spd - 48 with Hone Cavalry.
  • +spd, Fury reaches 40 spd - 46 with Hone Cavalry.

Olwen should always be receiving Hone Cavalry while attacking, so the important thing to keep in mind is she'll always be at worst one point faster than any +spd Fury 36 base spd unit (such as Fury Nino / Fury Linde). +spd Olwen running Life and Death is in a spd tier of her own.

Running Blarblade instead of Blarblade+ makes this build much cheaper to achieve, and is acceptable considering the huge atk values we're looking at (Blarblade Olwen achieves 70, 74 if +atk under optimal circumstances, which is sufficient).

Four parallel bolts
Dire Thunder A Fury 3
Reposition B Desperation 3
Luna C Ward Cavalry

Show Explanation/Analysis
  • Preferred nature: +spd/-hp or +atk/-hp
  • Weapon: Dire Thunder
  • Assist: Reposition / Ardent Sacrifice
  • Special: Luna
  • A slot: Fury 3 / Life and Death 3
  • B slot: Desperation 3 / Swordbreaker 3 / Lancebreaker 3
  • C slot: Ward Cavalry / Hone Cavalry

The standard quad-strike Luna build, applied with Olwen's Dire Thunder. Olwen's abysmal atk is mitigated by Dire Thunder's high might and the fact that Olwen can receive +6 atk with Hone Cavalry and potentially +8 from a two Goad Cavarly allies in range. There also aren't many units with adequate properties to properly tank this build (especially considering the lower average res when compared to average def in the metagame).

Swordbreaker and Lancebreaker are decent alternatives to Desperation for specialized countering (if your team needs an anti-sword or anti-lance nuke).

Look, mah, I can do it too!
Blárraven+ A Triangle Adept 3
Reposition B Quick Riposte 3
Iceberg C Threaten Atk 3

Show Explanation/Analysis
  • Preferred nature: +def/-spd or +res/-spd or +spd/-hp
  • Weapon: Blarraven+
  • Assist: Reposition / Ardent Sacrifice
  • Special: Iceberg
  • A slot: Triangle Adept 3 / Fury 3
  • B slot: Quick Riposte 3 / Vantage 3 / Bowbreaker 3 / Blue Tomebreaker 3
  • C slot: Threaten Atk 3

A better take on standard RobinM.

Ok, not really - more like a different take on standard RobinM, with res focus instead of def focus. Olwen's lower hp will also hurt a lot here.

The Raven tome + Triangle Adept combo works on virtually every unit physically capable of learning it, so of course Olwen can pull it off. She can sort of make it work well, too - but her low natural durability will definitely be a problem.

Don't expect miracles here.

  • Great spd.
  • Wields the Dire Thunder tome, which behaves like a 9 might Brave Blue Tome.
    • For reference, standard melee Brave weapons only exhibit 8 might. Dire Thunder's might is through the roof.
    • Quad-strike Luna is absolutely a viable prospect for Olwen.
  • She can be Odin on a horse if you give her a Blarblade tome.
    • This is a perfectly valid (if expensive) way to play her. Cavaliers have access to 10 more total firepower increase when compared with infantry units, which is not negligible as this turns her meagre 26 base atk into a much more impressive pseudo 36 equivalent base infantry atk in the right team - this is better than Linde's 35.


  • Low natural atk, negligible defenses.
    • (Her res is somewhat decent.)
  • Mostly irrelevant outside of Horse Emblem teams.
  • Requires heavy investment and lacks flexibility (quad-strike and Blade are her only decent builds).

Reinhardt and Olwen are similar in the sense that they're fragile blue cavalry mages and can both wield Dire Thunder (a unique, high might Brave Blue Tome). This is the entire extent of their similarities.

Olwen is a speed specialist of the pair (a single glance at her stat spread makes this obvious). Unlike Reinhardt, she can actually double things (even with Dire Thunder's spd penalty) but she lacks the firepower to do serious damage without proper support.

Thankfully, she can receive the almighty Hone/Fortify/Goad/Ward Cavalry buffs - this makes her largely superior to Odin, an otherwise comparable infantry neighbor in terms of stat spread.

  • The only existing magic user with reliable access to quad-strike (there is no standard Brave tome, dragon breath or staff).
    • Magical quad-strike is at a slight advantage when compared with physical quad-strike, because high-res foes are rarer than high-def foes in the metagame.
  • With adequate support, she reaches higher overall firepower in Blade configuration than both Linde and Nino (the most frequent Blade tome users). Unlike Tharja (the remaining fast Blade tome user), she also isn't red - which is advantageous with the current popularity of blue units.
  • Mostly unusable outside of Horse Emblem, and cannot do much if she's not actually receiving at least Hone Cavalry.
  • She "only" reaches 50 firepower in +atk quad-strike build, and that's including Hone Cavalry (46 if neutral atk).
    • This is adequate as long as the Hone Cavalry is active, but quickly breaks down if it isn't.
  • Forests. As is standard for cavalry units.
Team Options

At least tri-cavalier Horse Emblem is assumed (Olwen is irrelevant outside of heavy Horse Emblem), so you'll want to pair her with at least one red and one green cavalry unit. Among her partners, there should be one physical tank (Xander, Eldigan or Frederick) and you'll usually want a slower, complementary magic user (Cecilia or Leo).

Blade builds will want Hone and Fortify Cavalry allies (Goad Cavalry is appreciated on a potential fourth cavalry unit). Quad-strike builds will work better if partnered with one Hone and one\~two Goad Cavalry units.

There's little point in pairing Olwen with Reinhardt as they both get walled by roughly the same units.


It's important to insist on the fact that because Olwen relies on full Horse Emblem and careful position play to function, she is horribly bad in defense teams. The ease with which defense Olwen can be handled isn't representative of her actual potential, and many of the units that can be used to counter her can also be defeated by her.

With that being said, the #1 counter to enemy Olwen is Julia thanks to her high res, advantageous color and ability to destroy Olwen after baiting her. (Enemy Julia can be beaten by both quad-strike and Blade Olwen assuming she isn't running Triangle Adept - Triangle Adept Julia will completely wall and destroy every build of Olwen.)

Quad-strike builds are scared of units capable of breaking Luna's charging sequence (such as Guarding or Wary Fighter foes). Blade Olwen has no real counter, but she's annoyed by high res green units - especially Wary Fighters. Anything capable of denying Olwen's spd turns her into a weaker Reinhardt, at which point Reinhardt is just plain better.
