Fallen Gustav Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) HP Superbane ★★★☆☆
Atk (11) Attack Boon ★★★★★
Spd (3) Spd Bane ★★☆☆☆
Def (10) No Def IV ★★★★☆
Res (8) Res Bane ★★★☆☆

◯ = 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

Fallen Gustav's best IVs are +Atk and -Spd. Since Fallen Gustav is an offensive hero with a guaranteed follow-up attack, boosting his Atk yields the highest return in combat.

His Spd is an obvious dump stat and should be his bane of choice.

+Atk for a +10 merge

We recommend +Atk when merging Fallen Gustav up to +10 for similar reasons above.

Fallen Gustav is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he/she deals will be equivalent to his/her Atk minus the foe's Def stat.

Fallen Gustav Strengths

Headsman Glitnir has multiple effects that can impact combat

Fallen Gustav Attack Fire Emblem Heroes FEH

Fallen Gustav chops his enemies' heads off with his unique axe in Headsman Glitnir. This is a strong weapon that can influence combat heavily, assuming he meets the HP check.

Below is a summary of this weapon's effects:

Condition(s) Effect
Always Accelerates Fallen Gustav's Special trigger (cooldown count -1).
Fallen Gustav's HP ≥ 25% Inflicts Atk/Spd/Def-5 on foe during combat.
Fallen Gustav's HP ≥ 25% Grants Special cooldown charge +1 to Fallen Gustav per attack during combat.
Fallen Gustav's HP ≥ 25% Inflicts Special cooldown charge -1 to Fallen Gustav's foe per attack during combat.
Fallen Gustav's HP ≥ 25%
Foe can counterattack
OR
Foe initiates combat
Fallen Gustav makes a guaranteed follow-up attack.

Atk Smoke 4 increases bulk and denies enemy follow-up attacks

Years after the release of Atk Smoke 3, Fallen Gustav introduces the next tier of this skill with Atk Smoke 4.

In addition to the standard smoke effect of inflicting Atk-7 to nearby foes, this tier 4 skill also inflicts the Atk debuff on the foe, grants Def/Res+6 to its wielder for 1 turn and denies enemy follow-up attacks for 1 turn as well.

This skill is amazing on bulky units with low Spd, and Fallen Gustav certainly fits the bill.

Fallen Gustav Weaknesses

Reliance on Headsman Glitnir's conditions

Fallen Gustav heavily relies on meeting the HP check of Headsman Glitnir to have a big impact in combat.

When his HP is below the threshold, this mighty weapon becomes a glorified Slaying Axe+.

Thankfully, Fallen Gustav has the tools to remain healthy with his good bulk, Atk Smoke 4 denying follow-up attacks and inflicting an Atk debuff, and A/D Near Trace 3 allowing him to retreat after combat.

Keep Fallen Gustav healthy at all times to ensure that he remains relevant in battle!

Weak to Cavalry Effective Weapons

Fallen Gustav takes 1.5x damage from cavalry-effective weapons like Thani or Binding Reginleif, and one blow from this type of weapon is sure to take him down. Make sure you know what weapons you are up against before hopping too far into the line of battle!
