Iago Skills at 5★

Iago's Tome Might: 14　 Range: 2 Res+3. At start of odd-numbered turns, if a foe's HP ≤ unit's HP-3 & that foe isn't adjacent to another foe, inflicts Atk/Spd-4 and【Guard】on the foe. At start of even-numbered turns, if a foe's HP ≤ unit's HP-3 & that foe is adjacent to another foe, inflicts Def/Res-4 &【Panic】on the foe. 【Guard】 Inflicts cooldown charge-1 on target per attack during combat during its next turn. (Highest value applied. Doesn't stack.) 【Panic】 Turns bonuses on target into penalties through next action.

Blazing Wind Cooldown Count = 4 Before combat this unit initiates, foes in an area near target take damage equal to 1.5x (unit’s Atk minus foe’s Def or Res).

Atk Opening 3 At start of turn, grants Atk+6 to ally with the highest Atk for 1 turn. (Excludes unit.)

Iago Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★★★
Atk (24)		★★★★☆
Spd (5)		★★★☆☆
Def (6)		★★☆☆☆
Res (11)		★★★☆☆

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

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.

Neutral IVs by default!

As a hero obtainable only through Grand Hero Battle, Iago will always have neutral IVs by default. The only way to access IVs for this unit is through using Trait Fruits.

+HP/-Def

The best IVs for Iago are +HP and -Def. Iago's weapon, Iago's Tome, has a very good utility effect that relies on him having high HP to trigger. This means, the more HP Iago has, the easier it is to trigger Iago's Tome thus justifying a +HP IV. His Def is of less importance so it can be safely taken as a bane

+HP for a +10 Merge

We recommend a +HP IV when merging Iago to 10. This is for the same reasons above—making it easy for Iago to inflict Iago's Tome's effects on his enemies.

If you put HP/Atk 2 onto him, he can reach 53 HP at max merges.

Iago Best Weapon Refine

Effect of Iago's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Iago's Tome	SP: 400
Might: 14　Range: 2　HP: Grants Res+3. At start of odd-numbered turns, if any foe's HP s unit's HP-1 and that foe is not adjacent to another foe, inflicts Atk/Spd-6 and 【Guard】 on that foe through its next action. At start of even-numbered turns, if any foe's HP < unit's HP and that foe is adjacent to another foe, inflicts Def/Res-6 and 【Panic】 on that foe through its next action. At start of combat, if unit's HP ≥ 25%, grants Atk/Spd/Def/Res+4 to unit during combat. At start of odd-numbered turns, grants Def/Res+6, "foe cannot make a follow-up attack," and "neutralizes foe's bonuses during combat" to unit and allies within 2 spaces of unit for 1 turn. At start of even-numbered turns, grants Atk/Spd+6, "if unit initiates combat, unit makes a guaranteed follow-up attack," and 【Hexblade】 to unit and allies within 2 spaces of unit for 1 turn. If foe initiates combat or if foe's HP ≥ 75% at start of combat, grants Atk/Spd/Def/Res+4 to unit during combat. ：500　：200

We recommend the Special Effect Refine for Iago's Tome

Iago's Tome now features two distinct effects, offering both defensive and offensive support depending on turns. On odd turns, he and his allies gain defensive buffs such as Def/Res+6 and follow-up denial. Conversely, on even turns, he provides offensive support, granting Atk/Spd+6, a guaranteed follow-up, and 【Hexblade】 to him and his allies.

If you're planning to unlock this refine, make sure to be mindful of these conditional effects to avoid misuse and to ensure that you use them to your advantage.

Iago Roles, Strengths, and Weaknesses

Iago Roles

Iago - Nohr's Tactician 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

Iago is a ranged magic attacker (range = 2). 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.

Iago Strengths

Inflicts a penalty on foes with lower HP

Iago's exclusive weapon, Iago's Tome can debuff enemies whose HP is 3 values lower than Iago's. Just like Aversa, who can debuff units all over the map, this unit would work very well in an Aether Raid defense party.

Casts a bonus on ally with high Atk

The C skill Atk Opening 3 is a buff skill that gives +6 to the Atk of the ally who has the highest Atk stat.This skill has good synergy with heroes that already have a high offensive ability like double attack characters such as Reinhardt and Legendary Lif, blade tomes such as Nino, and characters that have the Bonus Doubler skill such as Valentine Alm and Legendary Roy.

Iago Weaknesses

Weak to foes with high HP and weak when taking damage

The penalty from Iago's Tome will not be activated unless Iago's HP is 3 values higher than the enemies' HP. It is hard to make use of one of Iago's biggest strengths when he is damaged or when he is against high HP heroes. To combat this, equip Iago with skills that increase maximum HP and bring allies that can heal Iago.

Iago as a Source Hero

Foddering for Atk Opening 3

We recommend using Iago to inherit the skill Atk Opening 3. He will learn Atk Opening 3 at 5 stars. However, since Iago is a Hero obtained from Grand Hero Battles, there is a limit on how many duplicates you can get. Think carefully if you want to use Iago as a fodder for Inheriting Skills.
