Olwen’s low base attack of 26 means that an attack boon is nearly mandatory if one is to use her. Speed is the next best boon followed by resistance. HP is next important, and finally, defense is her most useless stat.

Show Explanation/Analysis

With her naturally high speed, Olwen outshines Ursula as the best Blade tome user. Swift Sparrow is the optimal A slot skill for damage, giving her a nice boost to her offenses. However if you want to take advantage of her resistance, Fury is a great alternative that makes her better at running Ploy skills and luring enemies. It also gives her more speed on the enemy phase, making her harder to KO for fast enemies. There aren't many good choices for her B slot skill, but Desperation works well once you get under the threshold.

Show Explanation/Analysis

Olwen is also a great user of her tome Dire Thunder, but is somewhat overshadowed by her brother thanks to her lower attack. However she can run a quad-attack build thanks to her high speed. It operates in much the same capacity as her Blade build, but is more offensive-leaning and relies much more on Desperation.

  • Great stat distribution, most notably speed.
  • Combines cavalry class movement and buffs with Blade tome power.
  • Can function as a magic tank.


  • Low attack stat for an offensive unit, attack boon is nearly mandatory.
  • Requires more support than her competitors.


Olwen has long lived in the shadow of her brother, an easier-to use unit with more straightforward power. Like him, she is a blue cavalry mage, but differentiates herself thanks to her blazing speed and great resistance. Olwen requires a bit more investment than her brother, but makes up for this by being usable as a magic tank. She doesn’t have as much raw damage as top ranged attackers, but with a Hone Cavalry, Olwen is sure to get the job done.


Great stat distribution, most notably speed.

  • Olwen currently has the highest speed of any cavalry mage, at an astonishing base 34. Her main competition Ursula, sits at 32. Olwen also has good resistance, weighing in at 30. She is a great user of Ploy skills and can boost it higher with Fury. Although her defense is low, her high speed prevents most physical units from doubling her, making her more resilient than her brother Reinhardt.

Combines cavalry class movement and buffs with Blade tome power.

  • Olwen is a born offensive powerhouse, thanks to her access to Blade tomes, cavalry movement and strong buffs. Being able to move three spaces gives Olwen many more opportunities to score KO’s than Infantry such as Linde, Delthea and Lute. Blade tomes synergise very well with class specific buffs such as Hone Cavalry, giving +12 total stats from just one unit.

Can function as a magic tank.

  • Although Ursula can make the same claim, Olwen is one of few offensive units who can claim to be so effective at tanking magical damage. This is a major advantage over her brother Reinhardt, who is far too slow to avoid double attacks.

Low attack stat for an offensive unit, attack boon is nearly mandatory.

  • Olwen’s statline leaves her with one glaring weakness: a pitiful attack stat of only 26. While this can be remedied somewhat with A slot skills and the raw damage of Blarblade, she really needs an attack boon to be definitively superior to Ursula.

Requires more support than her competitors.

  • While Reinhardt can hit twice off the bat with his Dire Thunder, Olwen’s low attack means she relies on Blarblade, which requires support to function well. Although it is very easy to give her a Hone Cavalry buff, Reinhardt (as well as infantry mages who run Dark Aura) don’t need this support.
Team Options

Olwen can be run on any team as their token blue attacker, but the nature of Blade tomes means she really wants to be run with fellow Cavalry that can grant her substantial stat buffs. She can replace Reinhardt in most situations, trading some damage and support for magical bulk. Brave Lyn and Cecilia are great team-mates: Olwen can form a deadly dual-cavalry team with either of them provided they run Hone Cavalry. Reposition gives Olwen the power to remove allies from danger, and her high speed and resistance gives her a surprising amount of survivability. Green units with Distant Counter are common, so Olwen likes a strong red team-mate to back her up. Eliwood and Brave Roy are good mounted choices, but strong swords such as Ike, Ryoma, Mia and Ayra also do the job.


Unfortunately for Olwen, her brother’s reputation proceeds her. Nearly all teams run countermeasures to Reinhardt, and Olwen shares many of his counters. Green units with Distant Counter are her main concern. Hector, Dorcas as well as Distant Counter variants of Camilla, Titania, Amelia and Brave Ike also destroy Olwen. She has enough resistance to survive defensive green mages such as Boey and Merric, but can’t survive assaults from powerhouses such as Nino and Sonya. She must also beware of Brave Lyn, who ignores her buffs with Mulagir, and Reinhardt, who she cannot tank reliably without Deflect Magic.
