Jehanna Tethys Skills at 5★

Jehanna Dagger+ Might: 12　 Range: 2 If a skill compares unit's Spd to a foe's or ally's Spd, treats unit's Spd as if granted +7. At start of player phase or enemy phase, if unit is within 2 spaces of an ally, grants Atk/Spd+6, 【Dodge】, and "neutralizes penalties on unit during combat" to unit and allies within 2 spaces of unit for 1 turn. If unit is within 3 spaces of an ally, grants Atk/Spd/Def/Res+5 to unit and reduces damage from foe's first attack by 7 during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes), and unit's next attack deals damage = total damage reduced from foe's first attack (by any source, including other skills). Resets at end of combat. Effect: 【Dagger 7】

Dance Range: 1 Enables target to take another action. Cannot be used on units with Sing or Dance.

Firestorm Dance 3 If a skill like Sing or Dance is used, enables 【Canto (1)】 and grants Atk/Spd+6 and 【Desperation】 to target for 1 turn.

Jehanna Tethys Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (15)		★★☆☆☆
Atk (3)		★☆☆☆☆
Spd (10)		★★★★★
Def (4)		★☆☆☆☆
Res (12)		★★★★★

◯ = 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.

+Res / -Atk

The best IVs for Jehanna Tethys are +Res and -Atk. Jehanna Tethys has a great Res stat of base 42, raised to base 46 with a superboon. She can utilize that Res stat to both fulfill a secondary magic tank role as well as apply Res-based debuffs from support-type passive skills.

As a refresher unit, Jehanna Tethys isn't expected to attack her foes, especially with her abysmal base 31 Atk. It is a safe bane to take.

+Res for a +10 merge

We recommend +Res when merging Jehanna Tethys up to +10 to improve her ability to soak magic damage for her team.

Jehanna Tethys Roles, Strengths, and Weaknesses

Jehanna Tethys Roles

Tethys - Dancing Sands Roles

Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

Jehanna Tethys Strengths

Jehanna Dagger+ has multiple effects both in and out of combat

Jehanna Tethys's inheritable weapon Jehanna Dagger+ is a fantastic inheritable weapon on par with Arcane weapons.

It has a built-in Phantom Spd effect, and grants herself and her nearby allies Atk/Spd+6, 【Dodge】, and a Null Debuffs status effect at the start of each phase.

In combat, Jehanna Dagger+ grants Tethys Atk/Spd/Def/Res+5, 7 damage reduction on her foe's first attack, and damage reflection equal to the total amount of damage reduced from her foe's first attack in the current combat.

Jehanna Dagger+ has both support and combat effects and damage reflection is one of the best effects in the game, making it a valuable weapon to give to your favorite units.

Jehanna Tethys Weaknesses

Lack of Unique Skills

Jehanna Tethys suffers from not having any unique skills to call her own, making her unable to stand out amongst other units.

Flying refresher units are quite abundant in the game, and lacking an exclusive skill makes Jehanna Tethys replaceable by better units.

Weak to Bows

As a flying unit, Jehanna Tethys takes 1.5x damage from bows and weapons effective on flying units. Be sure to keep them out of the range of archers and leave them to other units.

Jehanna Tethys as a Source Hero

Value of Skills	★★★★☆

Jehanna Tethys has Jehanna Dagger+, Firestorm Dance 3, and Guidance 3 as inheritable options.

Jehanna Dagger+ is one of the best inheritable dagger weapons in the game, on par with Arcane daggers. We heavily recommend prioritizing it.

Additionally, by inheriting Gale Dance 1 or Blaze Dance 1 first, it is possible to acquire both Jehanna Dagger+ and Firestorm Dance 3 with one copy of Jehanna Tethys.
