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.


  • A +ATK boon gives him a fairly respectable Atk stat and pairs great with weapons like Poison Dagger.
  • +SPD is useful as always for ensuring multiple attacks on sluggish enemies and denying them from faster ones.

  • Summer Frederick can get rather tanky with a +DEF boon, improving matchups vs archers and distant counter units.


  • While -RES is a 4-point superbane, it is his least essential stat and already a bit too low to be reliable.

Show Explanation/Analysis
  • Preferred IV: +SPD or +ATK / -RES or -HP
  • Weapon: Kagami Mochi+ (+Spd) / Seashell+ (+Spd)
  • Assist: Draw Back / Ardent Sacrifice
  • Special: Bonfire / Luna
  • Passive A: Swift Sparrow 2 / Life and Death 3 / Darting Blow 3 / Fury 3
  • Passive B: Desperation 3 / Swordbreaker 3 / Bowbreaker 3
  • Passive C: Threaten Spd 3 / Flexible
  • Sacred Seal: Speed +3 / Attack +3

A standard player phase offensive dagger build. With all skills combined, Summer Frederick will reach a fairly respectable 48/43 Atk/Spd on initiation. While Kagami Mochi is preferred to let Summer Frederick fire off Bonfire procs as quick as possible, his native Seashell can be kept to increase his initiating Atk/Spd to 50/45 for his first combat (or continuously, with healing support). 

Draw Back best lets Summer Frederick assist with positioning while keeping himself safe. However, if Summer Frederick has an HP bane, which sets his HP to 38, Ardent Sacrifice will instantly put him into Desperation range with little effort, so long as no merges or blessings push him back over 40. Though for obvious reasons, avoid this if utilizing Seashell.

Swift Sparrow is the favored A slot skill, granting him some very welcome stats when initiating. Life and Death can push his Atk/Spd a point further at the cost of his defenses, wherein Summer Frederick can happily switch his special to Luna for greater damage on tankier targets. For other cheaper options, pick Darting Blow if still not entirely convinced by his speed, particularly if lacking a +Spd boon, or Fury to maximize his initial bulk plus give him a safe path towards Desperation.

Desperation will let Summer Frederick easily take down squishier foes he gets himself in range, which is fairly easy for him to do vs bows, distant counter units, or weaker mages thanks to his  decent defense stats. If opting more towards attack than speed, a breaker such as Swordbreaker or Bowbreaker will guarantee matchups vs the fastest units of those classes, such as Mia or Brave Lyn.

For the selfish option, Threaten Speed is a fairly easy skill to proc onto melee units that he can bait in range, and can go a long way to both guaranteeing his doubles and keeping him safe. Any other hone or spur can work just fine though, based on the support needs of his teammates.

Alternate: Fury 3

Alternate: Fortify Res 3
SP1,835SAttack +3

Show Explanation/Analysis
  • Preferred IV: +ATK / -RES or -DEF
  • Weapon: Kitty Paddle+ / Poison Dagger+
  • Assist: Draw Back
  • Special: Glimmer / Moonbow
  • Passive A: Death Blow 3 / Fury 3 / Life and Death 3
  • Passive B: Vantage 3 / Cancel Affinity 3
  • Passive C: Drive Res 2 / Fortify Res 3 / Flexible
  • Sacred Seal: Attack +3

A targeted assassin build that aims to make use of Summer Frederick's good attack to seek and destroy either mages or infantry. Kitty Paddle is the stronger option, while Poison Dagger is quite a bit more accessible. If using Kitty Paddle, a defense bane lets him keep up his rather low magical bulk in the event he must take a single hit.

To make sure his special is available when he needs it, Glimmer or Moonbow are used to benefit from their low cooldowns. Glimmer scales fairly great when used vs enemies his weapon is effective against, whilst moonbow is still quite useful and may help him salvage combats against other types of enemies.

Death Blow will provide him with maximum killing power. Life and Death comes close, and remains active on enemy phase, but at the cost of his defenses. Fury can give him the bulk needed to fight against enemies that can survive past the first hit.

Vantage is the optional B slot, as enemies that survive a round of combat will probably be in range where they will end up killing themselves as soon as they try to attack. When in range, Summer Frederick can easily bait and kill multiple squishy units at a time. Cancel Affinity is an alternative to give him a fighting chance vs mages running Triangle Adept in tandem with a Raven tome, but it is quite situational, and won't be needed for the majority of matches.

If Summer Frederick finds himself in a tough spot, it is usually going to be when fighting a higher powered mage. To alleviate this, a skill that boosts his ally's resistance, more easily allowing them to take care of that enemy, will work fairly well for him. Of course, virtually any team support skill works as always.

Kagami Mochi+ (+Def)
Alternate: Seashell+ (+Def)
A Close Counter
Reposition B Quick Riposte 3
Alternate: Seal Atk Spd 2
Alternate: Bonfire
C Threaten Atk 3
SP1,635SQuickened Pulse

Show Explanation/Analysis
  • Preferred IV: +DEF or +SPD / -RES
  • Weapon: Kagami Mochi+ (+Def/Spd) / Smoke Dagger+ (+Def/Spd) / Seashell+ (+Def/Spd)
  • Assist: Reposition
  • Special: Ignis / Bonfire
  • Passive A: Close Counter
  • Passive B: Quick Riposte 3 / Guard 3 / Seal Atk/Spd 2
  • Passive C: Threaten Atk 3 / Flexible
  • Sacred Seal: Quickened Pulse / Close Defense 3 / Quick Riposte 3

A defense focused set that aims to maximize his physical tanking power and retaliate with deadly Ignis procs. A defense refine and boon improve his staying power and ignis damage, though speed can still be used to attempt to deny enemy doubles.

Close Counter lets him bait and retaliate vs melee foes as well as ranged. Kagami Mochi pairs perfectly with Quick Riposte and a Quickened Pulse seal, letting any initiating enemy instantly be greeted with an Ignis. While not as powerful, Bonfire can be used with a Smoke Dagger or Seashell instead or if the Quickened Pulse Seal is unavailable. Close Defense is the strongest backup seal, further increasing his bulk vs melee targets, and pairs great with Threaten Attack, which weakens melee enemies that head toward him.

As an alternative, Guard can be equipped to stop any enemy special attacks, with Quick Riposte instead being used in the seal slot. His native Seal Atk/Spd is also a worthy budget option, working in tandem with his dagger's debuff to cripple any foe that remains alive for round two.


Summer Frederick is a seasonal dagger unit who is, when compared to other daggers, by all means relatively average. He has a fairly decent attack stat, though trailing slightly behind units like Sothe and Kagero. He has a workable speed stat, though truthfully one of the lower among daggers and not super impressive compared to speedy daggers like Gaius. He has a pretty beefy defense stat, though not quite at the level of tanks like Saizo. Essentially, he falls into the realm of jack of all trades, by no means bad, but not inherently a specialist in any category.

Thankfully, the buffs given to daggers through seals and the weapon refinery, as well as a multitude of new skills, have given Summer Frederick some much needed opportunity to push his stat spread in multiple directions. His attack, speed, and defense can all reach some welcome levels when invested into, Summer Frederick's only unfixable flaw being his inherently poor resistance. Though as long as one keeps wary of such attackers, he can overcome his average stats and provide for a wonderful summertime ally.


Good mix of attack and bulk

Summer Frederick's base defense of 28 is on the upper end of dagger units, and paired with a decent 40 HP.

While Saizo and Matthew sit slightly higher, at 33 and 30 defense respectively, Summer Frederick's 32 base attack is a welcome step up from their poor base attack stats of 29 and 25.

Nice exclusive weapon

Though somewhat of a niche weapon, the Seashell, which is only found on Summer Frederick, is a great generalist dagger that functions quite well on him.

However, recent new daggers such as the Kagami Mochi do offer some hefty competition, if one has it available.


Average statline

While mostly good, none of Summer Frederick's stats are great. His highest non-HP stat, attack, sits at just 32.  

For maximum power, he desperately needs to be tailored to a role, often with some expensive inherits.

Falters to magic

Summer Frederick seems to suffer from a severe case of bibliophobia, retaining the original Frederick's crippling weakness to spellbooks.

He both lacks the speed and the resistance to take hits from them in most cases.

Seasonal exclusivity

As a seasonal exclusive unit, it is very hard to merge him for stat boosts, or fish for optimal IVs.

Team Options

Summer Frederick's best allies are those that can take care of the mages that he wants to avoid, as well as those that can keep him safe and standing.

  • Deirdre, Fjorm, Micaiah, Winter Tharja, other high res units - anti-mage units will also go a long way, taking care of the units Summer Frederick is the most frightened of.

  • Elise, Priscilla, Maria, and other healers - whether they are staff users, or pseudo-medic units like Lucina, healers are a fantastic benefit to Summer Frederick whenever he is utilizing his default Seashell weapon.

  • Azura, Olivia, Ninian, and any other dancers  - units with Sing or Dance are great for bailing Summer Frederick out of tough situations by giving him a chance to either escape or secure a kill.

  • Reinhardt, Elincia, Bridal Cordelia, and other sweepers - Summer Frederick can actually do a decent job supporting allies himself, and map sweepers all greatly appreciate the opportunity to be attacking units that have had their defenses lowered by a dagger's AoE debuff. Ones that perform brave attacks particularly enjoy this, as a debuff can essentially translate to an extra 14 damage.

  • Reinhardt, Nino, Linde, Tharja - Summer Frederick's most obvious flaw, his poor resistance, can easily be taken advantage of by most powerful mages. Reinhardt's Dire Thunder will easily spell his death, as will most bladetomes and any other powerful nukers.

  • Arvis, Lute, Deirdre - Naturally, said res weakness also means that any unit that commonly makes use of ploys will always be afflicting Summer Frederick.

  • Male Robin, Sophia, Boey, Spring Camilla - a Raven tome also puts a pretty harsh stop to Frederick's combat potential. Even if Summer Frederick keeps his resistance at neutral, it only takes 43 attack for any Raven user with Triangle Adept to silence him in a single shot.

  • Hector, Winter Chrom, Zelgius, Adult Tiki, other dragons - Most powerful distant counter tanks will also give Summer Frederick a deal of trouble. Generally bulkier than he is, they will probably take him down first, especially in the case of dragon units who will be hitting Summer Frederick's resistance stat.

  • Micaiah - The AoE debuff provided by most daggers after refining them can easily transform into a liability against Micaiah, who can reverse debuffs with Sacrifice.
