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.

Neutral IVs by default!

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

+Atk/-Spd

The best IVs for Sonia are +Atk/Spd. Because her Spd stat is already low, it's good to have it as a bane and increase her Atk.

With the Quick Riposte 3 seal, she'll potentially be able to tank and counterattack ranged enemy units.

However, because Sonia's not a very powerful unit to begin with, we recommend not investing a Trait Fruit in her to change her stats.

+Spd for +10 Merge

If you are merging Sonia, it's recommended to increase her Spd. This, at least, will get her to 32 Spd at +10, and reinforcing this with skills and Seals will allow her to potentially double enemy units.

If you would like to focus on one-shotting enemy units, you can +Atk her instead.

Sonia Best Builds

Budget Sonia

： Blárserpent+ ： Reposition ： Glacies ： -

： Fort. Def/Res 2 ： Guard 3 ： Threat. Atk/Res 2 ： Quick Riposte 3 ： -

How to Use, Explanation

By inheriting an inexpensive Guard 3, Sonia is able to achieve more bulk as there won't be as much Special attacks hitting her. The Quick Riposte 3 Sacred Seal is good on her as it provides her a way to nail in follow-up attacks in the enemy phase.

Close Reversal Sonia

HOT
： Pact Blooms+ ： Reposition ： Iceberg ： -	： Close Reversal ： Lull Atk/Res 3 ： Atk Smoke 3 ： Quick Riposte 3 ： -

How to Use, Explanation

This build requires more investment, but makes Sonia a good tank due to her high stats. Use either the Def or Res refine of Pact Blooms+ depending on the type of tank you want her to be. The Quick Riposte 3 Seal is required on her so that she makes a guaranteed follow-up attack.

Tank Sonia

HOT
： Pact Blooms+ ： Reposition ： Iceberg ： -	： Mirror Stance 3 ： Lull Atk/Res 3 ： Joint Drive Atk ： Quick Riposte 3 ： -

How to Use, Explanation

Compared to the budget Sonya build, this requires premium fodder—but it is way more both offensive and defensive ends. Pact Blooms+ can easily be obtained from another free unit Valentine's Veronica so the only expensive skills you need to get are Lull Atk/Res 3 and Joint Drive Atk. If you can't afford Joint Drive Atk, Odd Atk Wave 3 can work as a cheaper substitute.

Sonia Roles, Strengths, and Weaknesses

Sonia Roles

Sonia - Inhuman Beauty 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

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

Sonia Strengths

Extremely Durable Mage Unit

Sonia has very high Def and Res, which makes her a good candidate as a tank if you would like to build her as such.

Giving her Close Counter will enable her to tank both melee and ranged units and counterattack.

Sonia Weaknesses

Lack of a Prf Weapon Makes Her a Mediocre Unit

Since Sonia does not have a Prf weapon, she will have a hard time scoring high in the Arena and is easily powercrept by other mages.

Brunnya, for instance, is just as tanky and comes with a Prf weapon of her own.

If you do like Sonia, however, you can inherit Pact Blooms+ on her instead of using her default weapon, so she can give herself some survivability.

Low Spd Makes Her Easily Doubled

Despite being tanky, Sonia possessed low Spd, making her easily doubled by a lot of other units.

You can mitigate this by giving her Quick Riposte 3, so she can make a follow-up attack.
