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.


  • +SPD: This puts Siegbert at an exceptional 38 Speed, allowing him to double a majority of units in the arena in tandem with Dark Greatsword, such as Amelia and Minerva. A Hone Cavalry would enable him to double common Ayra builds found in Arena.

  • +ATK: A boon in Attack is great for simply boosting his offensive capability in general. 


  • DEF: While Siegbert prefers more Attack or Speed, a boon in Defense helps to tank more physical hits, especially if he's running Bonfire / Ignis. Likewise, a bane in Defense does not severely gimp Siegbert's offensive prowess and can be safely lowered if need be. 
  • HP: Siegbert's HP is too low to properly take advantage of health boost skills, and so can be safely lowered. A bane in health also makes it easier to trigger HP-threshold skills such as Desperation.


  • -RES: 16 base Resistance is too low to be salvageable, making a bane the least detrimental to his overall performance.

  • Weapon: Dark Greatsword
  • Assist: Reposition / Swap
  • Special: Draconic Aura  / Bonfire / Moonbow / Dragon Fang / Galeforce
  • Passive A: Swift Sparrow  / Fury / Heavy Blade / Death Blow 
  • Passive B: Desperation 
  • Passive C:  Fortify Cavalry / Atk Tactic / Flexible
  • Sacred Seal: Speed +3 / Attack +3

Boasting the highest Speed of all cavaliers alongside Brave Lyn, Siegbert can run an offensive build to deadly effect. Swift Sparrow complements his Greatsword’s passive like bread and butter, giving him +8 Atk/Spd upon initiation. Fury provides Siegbert with more utility on Enemy Phase, increasing his Defense while making it easier for him to drop to Desperation range. Heavy Blade; meanwhile, grants him a role akin to Brave Roy with the additional benefit of having higher physical bulk and Galeforce being a viable option should he run it.

Draconic Aura is the preferred Special on Siegbert, as it takes advantage of his high Attack and weapon passives.  Moonbow is another alternative, proccing against every melee encounter should he double. Bonfire keeps his damage at a constant 15 per activation without buffs, making it favorable in occasions where Siegbert needs to tank a hit on enemy phase. Desperation is the B skill of choice, letting him dish more damage against opponents while he is at low health.

With Siegbert being an offensive unit in a cavalry-centric, Fortify Cavalry is recommended in order to provide more overall bulk to his teammates. His default Atk Tactic is a solid option as well should you run him on a mixed team. For Sacred Seals, Siegbert want Attack/Speed +3 in order to boost his offensive prowess even further.


A Siegfried by another name
Dark Greatsword A Distant Counter
Reposition B Quick Riposte 3
Alternate: Dragon Fang
C Fortify Cavalry
Alternate: Atk Tactic 3
SP1,635SDistant Def 3

Show Explanation/Analysis
  • Preferred IV: +SPD or +ATK / -HP
  • Weapon: Dark Greatsword
  • Assistl: Reposition / Swap
  • Special: Bonfire / Ignis / Moonbow
  • Passive A: Distant Counter
  • Passive B: Quick Riposte  
  • Passive C : Fortify Cavalry / Atk Tactic / Flexible
  • Sacred Seal: Distant Def

Although not wielding the legendary Siegfried, Siegbert is more than capable of utilizing a Distant Counter build thanks to his above-average offenses and Speed. Quick Riposte ensures a second attack from him, especially against fast swords such as Ayra and Mia. The choice of special depends on your preference with Bonfire against faster opponents, Moonbow for consistent damage, or Ignis to deliver a painful nuke at the cost of a longer cooldown.

With an Enemy Phase orientated build, Siegbert wants Distant Def in order to handle mages better. Close Def 3 is also another alternative to tank melee opponents instead.


As the son of Xander, Siegbert is ready to take his father’s mantle by proving himself on the battlefield. The apple, however, fell extremely far from the tree. While Xander is best suited for being a bulky Distant Counter unit, Siegbert distinguishes himself by being a deadly Player Phase nuke.

This is thanks to his excellent offensive statline as well as his signature weapon, Dark Greatsword, granting him a significant boost to his Attack and Speed upon initiation. Furthermore, he also sports a solid 31 base Defense. The combination of these traits makes Siegbert a fearsome attacker, especially when receiving powerful class-exclusive buffs such as Hone Cavalry.

It’s not all bed and roses for him though, as Siegbert’s Rresistance is at an atrocious 18 at neutral. This makes him highly vulnerable against many magical attacks. Nevertheless, play to his strengths, and you won’t be disappointed.


High offenses 

34 Attack and 35 Speed are excellent for a cavalier. These stats can be boosted even further under a cavalry-based team.

Dark Greatsword

Essentially Swift Sparrow 2 built into a weapon, it cements Siegbert’s role as a dangerous attacker. Coupled with cavalry movement, Siegbert possesses incredible reach to complement his already impressive initiation.

Decent physical bulk

31 base Defense is impressive for a primarily offensive unit. Combined with his innate Speed makes him less susceptible to being doubled and knocked out.


Poor Resistance 

Base 16 Resistance puts him in a vulnerable position against powerful red/blue magical attacks. This also means Siegbert is easily susceptible to Ploy users such as Arvis and Lute and as such, must be careful in avoiding being debuffed by them.

Rise of anti-cavalry terrain/weapons

With the introduction of trenches, maps that feature them hinders Siegbert’s mobility. Thanks to forgeable anti cav weaponry, refined Ridersbane/Blarwolf will easily put an end to Siegbert’s conquest in addition to ignoring Hone/Fortify buffs.

Team Options

Siegbert thrives on a cavalry-centric team, as he is able to receive powerful class-exclusive buffs such as Hone Cavalry. , he struggles most against physical blue walls, so green units are best suited for teammates.

  • Cavalry: Eirika (SM), Gunnthrá, Olwen (WT), Legendary Ephraim, and Reinhardt all make for fantastic teammates by providing Siegbertwith powerful buffs such as Hone Cavalry and Fortify Cavalry while keeping up with his high movement.
  • Refreshers: Extremely versatile in general, refresh units such as Azura, Performing Azura, Lene, Ninian, and Performing Inigo all match perfectly with an aggressive hero like Siegbert, enabling him to either continue rushing down the opponent or retreat to safety.
  • Strong greens: Hector, Myrrh, Fae, and Dorcas can handle both physical and magical threats that may post a threat to Siegbert. 

Siegbert has absolutely atrocious Resistance, so any well placed blue magical attack will severely dent him. Past that, any bulky blue with damage mitigation skills such as Steady Breath or Close Def will be able to wall Siegbert will little problems.

  • Magical damage dealers: Nowi, Delthea, Lute, Reinhardt, and Linde can all make short work of Siegbert’s sparse magical bulk.

  • Physically bulky blues: Fallen Hardin, Effie, Winter Robin, Female Corrin, and Lukas can easily mitigate the amount of damage that Siegbert can do thanks to their high physical bulk and Weapon Triangle advantage. In addition, units that utilize the skill Guard can completely wall him off by preventing him from activating his Specials.
