If unit's HP ≥ 25% at the start of combat, after combat, if unit attacked, inflicts 【Deep Wounds】on target and foes within 2 spaces of target. If foe's range = 2, calculates damage using the lower of foe's Def or Res. 【Deep Wounds】Unit's HP cannot be healed through its next action.

Rally Up Atk+ Range: 1 Grants Atk +6 to target ally and allies within 2 spaces of target (excluding unit) for 1 turn.

AR-D Def/Res 4 If defending in Aether Raids, grants Def/Res+X during combat. (Calculates X based on number of your defensive structures ≥ 5 structures grants +11; 4 grants +7; ≤ 3 grants +3. Destroyed defensive structures are not counted.)

Dragon Wall 3 If unit's Res > foe's Res, reduces damage from attacks during combat and from area-of-effect Specials (excluding Røkkr area-of-effect Specials) by percentage = difference between stats x 4 (max 40%).

If unit is within 2 spaces of an ally, grants Atk/Def+4 to unit during combat, and also, if unit's Atk > foe's Res during combat, unit's first attack deals damage = 30% of unit's Atk minus foe's Res.

HP (18)		★★★☆☆
Atk (11)		★★★★☆

◯ = 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

We recommend a +Atk/-Spd IV for Múspell.

His Atk is a superboon and he will benefit greatly from the increased stat for his one-shot potential.

Múspell's Spd is a superbane and is not important for his combat potential, so it's safe to take as a bane.

+Atk for a +10 Merge

We recommend taking +Atk as your boon of choice when building a +10 merged Múspell.

His extremely high Atk makes him a powerhouse that and no one would want to mess with.

Múspell Roles, Strengths, and Weaknesses

Múspell Roles

Múspell - Flame God 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

Múspell is a close magical 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.

Múspell Strengths

Flamelick Breath applies Deep Wounds

Múspell's buffs from Flamelick Breath and Domain of Flame are shown here.

Flamelick Breath is an amazing weapon, as it not only gives Múspell Atk/Spd/Def/Res+5 during combat if his HP ≥ 25% but also inflicts【Deep Wounds】on his target and their nearby allies.

This makes Múspell a good offensive unit, as he can attack first and inflict the debuff to as many enemy units as possible so the rest of his team can clean up.

Domain of Flame turns high Atk units into powerhouses

Domain of Flame's extra damage is shown in the damage calculation, with Múspell dealing 50 damage to this Sword Cavalier instead of 39.

Múspell's exclusive C skill is useful both for himself and allies with very high Atk.

If their Atk is higher than their target's Res, their first attack will deal damage = 30% of their Atk minus their target's Res.

This makes him good friends with a large number of purely damage units, as they can take advantage of this skill to deal large amounts of damage, possibly one-shotting enemy units on the first attack.

Múspell Weaknesses

No Distant Counter means that he can be kited

Múspell has no Distant Counter in his kit, which means that he can be kited by ranged units.

Even if he reduces damage, his HP can be slowly chipped away at in order to take him down.

Weak to Cavalry Effective Weapons

Because he is considered a cavalry unit, 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/her down.

Make sure you know what weapons you are up against before hopping too far into the line of battle!

Weak to Dragon Effective Weapons

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/her down.

Múspell as a Source Hero

Value of Skills	★★★★★

Inherit AR-D Def/Res 4, Rally Up Atk+, or Dragon Wall 3

Múspell can be used to inherit AR-D Def/Res 4, Rally Up Atk+, and Dragon Wall 3.

Currently, Múspell is the only unit with AR-D Def/Res 4, but you can manage to maximize inheritability by getting AR-D Def/Res 1-3 from Kjelle, and inheriting Dragon Wall 1-2 from Seiros.

This way, you can get both AR-D Def/Res 4 and Dragon Wall 3 from 1 copy of Múspell!
