Boons

  • +ATK: Attack is a superboon and without a doubt the best nature that Surtr can receive, as it boosts his already incredible base value to whopping 43!

  • +DEF: A boon in Defense is another great choice as well as another superboon. With this nature, Surtr has the absolute highest base Defense in the entire game at a colossal 44.

Neutral

  • RES: Although raising it is not a priority, Surtr would rather avoid lowering his impressive Resistance of 33 in order to keep his magical bulk intact.

  • HP: Similarly, Surtr prefers to keep his HP neutral in order to keep his overall bulk intact as well as avoiding HP-targeting skills such as Panic Ploy.

Banes

  • -SPD: Surtr’s Speed is far too low to make any effective use of, making it the easiest stat to drop.

  • Assist: Swap / Pivot

  • Passive C: Surtr’s Menace / Armor March

  • Sacred Seal: Quick Riposte / Quickened Pulse

This build takes advantage of Surtr’s status as an armored unit in order to make him an unstoppable force during both Player and Enemy Phase. For his IVs, Surtr appreciates boons in key stats such as Attack and Defense. A boon in Attack makes for a strong overall option by boosting his raw damage significantly while a boon in Defense further adds to his already incredible physical bulk as well as the damage from Defense-scaling Specials such as Bonfire and Ignis.

The choice between Distant Counter and a Breath skill for the A slot depends on what type of opponents Surtr is likely to take on. Distant Counter grants Surtr much more general coverage by allowing him to retaliate against ranged opponents while any choice of Breath skill make him much stronger in handling melee threats thanks to the increased Special cooldown charge as well as the stat boost that they provide during Enemy Phase.

Bold Fighter is a crucial part of this set, as it grants Surtr a strong presence during the Player Phase. Not only does it guarantee his follow-up attack on initiation, the Special cooldown acceleration it provides allows Surtr to potentially activate Bonfire every single round of combat. Surtr’s exceptional Attack coupled with the sheer power of his Special activation will cleave through just about any opponent he initiates on.

Surtr’s Menace is a unique and incredibly powerful skill that seldom needs to be replaced. Not only does it give Surtr a +4 buff to all his stats, it also reduces the stats of any opponent within 2 spaces by 4 as well, creating a total stat difference of 8. However, due to armored units being naturally restricted to only one movement, it can be difficult to get consistently get Surtr into a position where he can initiate on his opponent. This makes Armor March a good choice of C skill for him to carry should another teammate not be using it already.

Both the Quick Riposte and Quickened Pulse Sacred Seals are key in maximizing Surtr’s Enemy Phase potential. Quick Riposte guarantees Surtr’s follow-up attack as well as his Special activation when initiated on at the cost of being more susceptible to follow-up attacks. Meanwhile, Quickened Pulse lowers the initial cooldown of Bonfire to 2. When combined with a Breath skill, Surtr can activate his Special on his very first counterattack, allowing him to take out opponents in a single hit before they have the chance to double him. In particular, this can be the deciding factor in his matchups against Ayra and Legendary Eirika

Show Explanation/Analysis
  • Preferred IV: +ATK or +DEF or +RES / -SPD

  • Special: Bonfire / Aether

  • Passive A: Distant Counter / Breath Skills / Steady Stance

  • Passive B: Wary Fighter

  • Passive C: Surtr’s Menace

  • Sacred Seal: Distant Def / Close Def

Surtr’s unique skills synergize extremely well with his high durability by brutally punishing opponents that can’t take him out in a single round of combat. With both Sinmara and Surtr’s Menace, any opponents within 2 spaces of Surtr will take 20 damage and a -4 reduction to all their stats. If that wasn’t crippling enough, Surtr will also gain a buff of +4 to all of his. This set focuses on elements from Surtr’s base kit in order to make him a wall that strikes down any opponent that so much as comes near him.

In addition to Attack and Defense, Resistance can also make for a good choice of boon in order to even out his overall bulk as well as making it harder for strong magical attackers to defeat Surtr in a single round of combat. As for his Special, Bonfire remains a very strong choice of Special for sheer damage alone. Alternatively, Aether can also make for a good option by giving Surtr self-sustainability through its healing aspect at the cost of a longer cooldown.

Distant Counter is still the best all-around option by giving Surtr coverage over ranged units while Breath skills help significantly against other melee opponents. If neither are available, Surtr’s native Steady Stance 4 makes for a great alternative to Breath skills. At the expense of lowering his Special cooldown, Steady Stance 4 grants Surtr an unparalleled +8 boost to his Defense when initiated on while also preventing his opponent from activating their Special.

Wary Fighter is the crux of this set, as it greatly reduces the amount of damage that Surtr takes in a single round of combat by preventing his opponent’s follow-up attack. Since very few units have any hope of defeating Surtr in a single hit, the opposing team will often be stuck in the AOE of Surtr’s skills during the next turn. Finally, both the Distant Def and Close Def Sacred Seals complement this Enemy Phase-oriented playstyle perfectly by further reducing damage taken from physical and ranged opponents respectively when initiated on.

Introduction

Between his story self and his iteration as a playable unit, Surtr retains everything that made him strong and then some. Statwise, Surtr’s immense BST is very well distributed with almost every single base covered. Sporting incredible values in Attack (superboon), Defense (superboon), HP, and Resistance, the only apparent weakness that Surtr has is his abysmally low Speed making him susceptible to follow-up attacks. In addition to this, Surtr’s status as an armored unit grants him access to powerful skills such as Bold Fighter along with armor-exclusive buffs.

Surtr’s strength goes even further than his stats and classtype. His unique skills, Sinmara and Surtr’s Menace, make it extremely dangerous for opponents to even stand near him. In addition to further boosting his monolithic Defense, Sinmara deals 20 damage to any opponents within 2 spaces of him at the start of his turn while Surtr’s Menace hits them with a massive debuff of -4 to Atk/Spd/Def/Res while Surtr gains the same in a buff. In other words; at the start of any turn, opponents within 2 spaces take 20 damage and get a deficit of 8 to each stat against Surtr.

Overall, Surtr is a top-tier unit with very few weaknesses barring his low Speed and can be an unstoppable juggernaut on almost any team.

Strengths

Insane Attack

With a fantastic base value of 39 and having a superboon, Surtr hits hard with his raw Attack alone, granting him consistently high damage output in both Player and Enemy Phase.

Fantastic Mixed Bulk

With an unparalleled mixed bulk of 90/83, Surtr is great at taking both physical and magical attacks.

Sinmara

In addition to further boosting his Defense, Sinmara burns 20 health off of any opponent within 2 spaces of Surtr at the start of his turn.

Surtr’s Menace

If you didn’t think standing near him was dangerous enough, Surtr’s unique C skill hits his opponents with a massive debuff while simultaneously granting him a significant buff.

Armored

Being an armored unit comes with several benefits. These include having a much higher BST compared to other class types, access to class-exclusive skills such as Bold Fighter, and the ability to receive powerful buffs from armored teammates such as Hone Armor and Ward Armor.

Weaknesses

Low Speed

Surtr’s abysmally low Speed makes him highly susceptible to getting doubled, greatly increasing the amount of damage he takes as well as allowing his opponent to charge their Special.

Vulnerable​ ​​​​​​to Effective Damage

As an armored unit, Surtr will receive 1.5x damage from armor-effective weapons. Armorslayer and Dawn Suzu are especially problematic for Surtr, as he has the Weapon Triangle disadvantage against them.

Poor Mobility

Surtr’s class type limits his movement to only one tile. This makes him reliant on assist skills such as Pivot or team support through the use of Armor March to quickly move across the map.  

Team Options

  • Armors: Brave Hector, Effie, Zelgius, Black Knight, Halloween Myrrh, and Halloween Jakob are all powerful allies that can provide Surtr with useful buffs such as Armor March and Hone Armor.

  • Refreshers: Summer Micaiah, Olivia, Lene, Silvia, Ninian, Azura, and Performing Azura are among many great choices that provide Surtr with fantastic support through an extra turn, allowing him to move into more favorable positions.

  • Guidance Fliers: Tana, Elincia, Legendary Ryoma, Cherche, Bridal Ninian, YT-Olivia, and generally any other flier can greatly improve Surtr’s mobility through the use of the skill Guidance. Bridal Ninian and YT-Olivia also double as refreshers.

  • Strong Blues: Nowi, Reinhardt, Ephraim, Ophelia, Ishtar, and Ephraim all perform well in checking both physical and magical reds that may pose a threat to Surtr.

Counters

  • Physically Bulky Reds: Zelgius, Halloween Myrrh, Adult Tiki, Black Knight, Arden, and Zephiel can all mitigate the amount of damage that Surtr can do with his raw Attack alone thanks to their high physical bulk and Weapon Triangle advantage. In addition, units that utilize the skill Guard can potentially wall him off completely by preventing them from activating his Special.

  • Effective Damage: Due to his class type, Surtr has a natural weakness to armor-effective weapons. Common users include Bartre, Hana, and Summer Micaiah.
