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.

+Spd/-Def

The best IVs for Tailtiu are +Spd and -Def. A higher Spd stat allows Tailtiu to prevent follow-up attacks against her and helps her make follow-up attacks on her own. This boosts both her offensive and survivability capabilities. Her low Def is of less importance, so it is safe to take Def as a bane.

+Spd for a +10 Merge

We recommend a +Spd IV when merging Tailtiu to 10. With this IV, she can reach a Spd stat of 42 at max meges. This will give the same benefits mentioned above. If you plan to use Blárblade+ instead of Tome of Thoron, you are better off getting a +Atk IV instead.

Tailtiu Best Builds

Refined - Push Tailtiu

HOT
： Tome of Thoron ： Draw Back ： Luna ： -	： Atk/Spd Push 4 ： Desperation 3 ： Atk/Spd Menace ： Flashing Blade 3 ： -

How to Use, Explanation

Once Tailtiu activates her special effect refine, and her first Special attack, she can rapidly rain down powerful Special attacks with this build! When that happens, Atk/Spd Push 4 will have already activated Desperation 3. This means Tailtiu can go on a one-sided rampage against enemy units!

Desperate Fury Tailtiu

： Tome of Thoron ： Draw Back ： Glimmer ： -

： Fury 4 ： Desperation 3 ： Joint Drive Atk ： Fury 3 ： -

How to Use, Explanation

This build uses the recoil from Fury to activate Desperation and allow consecutive attacks for future engagements. Make sure to keep the unit alive after the first combat since they will be in exploitable HP ranges!

Tailtiu Best Weapon Refine

Effect of Tailtiu's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Tome of Thoron	SP: 400
Might: 14　Range: 2　HP: At start of turn, if unit’s HP ≤ 75% and unit’s attack triggers Special, grants Special cooldown count-1, and deals +10 damage when Special triggers. If unit initiates combat, grants Spd+6 during combat. ：500　：200

We recommend the Special Effect Refine for Tome of Thoron

It is a straightforward upgrade that grants Tailtiu +6 Spd whenever she initiates an attack. It helps her in her primary role as a player phase tome attacker. This upgrade goes well with the B skill Desperation 3! If Desperation triggers and Tailtiu is fast enough for a follow-up attack, she will be able to take out units without receiving damage.

Tailtiu Roles, Strengths, and Weaknesses

Tailtiu Roles

Tailtiu - Thunder Noble 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

Tailtiu is a ranged magic attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent toher Atk minus the foe's Res stat.

Tailtiu Strengths

Tome of Thoron has Wrath 3 built-in!

Tome of Thoron speeds-up Tailtiu's special cooldown and grants +10 pure damage to her whenever her special is activated. If you inherit a powerful special onto Tailtiu like Luna or Glimmer,you will be able to shred through most enemies that does not have an abnormally high Res stat especially if Tailtiu scores the follow-up attack. This synergizes well with Tailtiu's play style, kit and stats as she will have decent amounts of Spd at max investment. Having a high Spd means you score follow-up attacks more often and both those attacks help in activating a Tome of Thoron-charged Special attack!

Possesses another powerful weapon in Blárblade+

Blárblade+,Tailtiu's alternative weapon, is a Blade tome that takes Tailtiu's bonuses and adds them to the damage she deals. This is at the cost of delaying her special attack. If you prefer to use this weapon over Tome of Thoron, then you should make sure that she gets lots of support from your team. It is a very powerful tome, but it requires a lot of support and buffs from Tailtiu's allies. It can be said that Tome of Thoron's strengths is that it is less dependent on other factors.

Possesses buffs for allies

Tailtiu's base kit contains Rally Spd/Res which is an assist skill that boosts an ally's stats and Drive Spd 2, a passive skill that grants Spd to allies within 2 spaces. This allows her to both support and dish out damage using her base kit. Although we recommend that you use a Tailtiu as a full-on attacker so you should replace these skills as soon as possible. Check out her builds section to learn which skills as best for her.

Tailtiu Weaknesses

Low Defenses

Tailtiu's Def and Res sit at only 17 and 26 respectively. This makes her extremely fragile. Be mindful of her position against enemies that can take her out and watch out for units that can score a counterattack on her! This is the reason why we recommend Desperation 3 in her builds as she has the offensive fire power to take out enemies without taking damage. For Tailtiu, a good offense is the best defense you can give her.
