Flame Tribe Múspell Skills at 5★

Breath of Flame Might: 16　 Range: 1 Accelerates Special trigger (cooldown count-1). At start of turn, if Special cooldown count is at its maximum value, grants Special cooldown count-1. If unit initiates combat or is within 2 spaces of an ally, grants Atk+6 to unit and inflicts Atk-6 on foe during combat, unit makes a guaranteed follow-up attack, and reduces the percentage of foe's non-Special "reduce damage by X%" skills by 50%. If foe's Range = 2, calculates damage using the lower of foe's Def or Res.

Moonbow Cooldown Count = 2 Treats foe's Def/Res as if reduced by 30% during combat.

Atk/Def Catch 4 At start of combat, if foe's HP=100% or if【Penalty】is active on foe, grants Atk/Def+7 to unit during combat. At start of combat, if foe's HP=100% and【Penalty】is active on foe, grants an additional Atk/Def+2 to unit during combat. 【Penalty】 All effects that last "on foe through its next action."

Dragon's Wrath 4 Reduces damage from foe's first attack during combat by 25%. If unit's Atk > foe's Res, unit's first attack deals damage = 25% of unit's Atk minus foe's Res during combat.

Domain of Flame Grants Atk/Def+4 and the effect "if unit's Atk > foe's Res during combat, unit's first attack deals damage = 30% of unit's Atk minus foe's Res" to allies within 2 spaces during combat.

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★☆☆
Atk (13)		★★★★★

Def (8)		★★★★☆
Res (8)		★★★☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units

Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Atk / -Spd

The best IVs for Flame Tribe Múspell are +Atk and -Spd. Flame Tribe Múspell's Atk is quite high at base 43 and is boosted even further by his other skills.

His Spd is quite lackluster at base 26 and taking it as a bane isn't going to change any of his matchups.

+Atk for a +10 Merge

We recommend +Atk when merging Flame Tribe Múspell to +10 for similar reasons above. Atk is his most important stat and should be boosted as much as possible to obtain the most kills.

Flame Tribe Múspell Roles, Strengths, and Weaknesses

Flame Tribe Múspell Roles

Múspell - Raging Inferno Roles
Close-Physical	Ranged-Physical	Close-Magic	Ranged-Magic
Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

Flame Tribe Múspell is a close magic attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Res stat.

Flame Tribe Múspell Strengths

Breath of Flame is a great wallbreaker weapon

Flame Tribe Múspell's Breath of Flame is a great weapon to break down sturdy foes with. It has a Time's Pulse effect, allowing 2 charge Specials to always be pre-charged at the start of each turn.

During combat, it grants Atk+6 to Flame Tribe Múspell, inflicts an Atk-6 penalty onto his foe, grants him a guaranteed follow-up attack, and halves the effectiveness of non-Special damage reduction skills.

Damage reduction is a common ability in the current metagame, and being able to pierce through it, albeit at half effectiveness, is very powerful. Unfortunately, it only pierces through non-Special damage reduction, so it will be ineffective against the Hardy Fighter and Pavise combination.

Domain of Flame grants bonus damage to Múspell and his allies

Flame Tribe Múspell also carries Domain of Flame, similar to his original version.

This skill is amazing in granting bonus damage for both Flame Tribe Múspell and his allies. It is one of the best C skills in the game in helping units break down enemy tanks, granting Atk/Def+4 and bonus damage on the unit's first attack equal to 30% of unit's Atk minus the foe's Res.

Flame Tribe Múspell Weaknesses

Weak to Cavalry Effective Weapons

Flame Tribe Múspell takes 1.5x damage from cavalry-effective weapons like Ridersbane+ or a Wolf weapon like Keen Rauðrwolf+, and one blow from this type of weapon is sure to take him down.

Weak to Dragon Effective Weapons

Flame Tribe Múspell takes 1.5x damage from dragon-effective weapons like Sealed Falchion or Ífingr, and one blow from these types of weapons is sure to take him down.

Flame Tribe Múspell as a Source Hero

Value of Skills	★★★★★

Flame Tribe Múspell has Atk/Def Catch 4 and Dragon's Wrath 4 as great inheritable options.

Dragon's Wrath 4 should be the skill of choice for inheritance, as it is a rare tier 4 B skill, and only found on Flame Tribe Múspell (as of September 2022). Its lower tier versions, Dragon's Wrath 3 and below, are also only found on another seasonal unit, Halloween Sothis. This skill is simply very rare.
