Delthea Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (16)		★★☆☆☆
Atk (24)		★★★★☆
Spd (8)		★★★★★
Def (3)		★☆☆☆☆
Res (7)		★★★☆☆

◯ = 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.

+Spd/-Def

The best IVs for Delthea are +Spd and -Def. With this IV, she will reach a Spd of 37 at Lv. 40 A higher Spd stat allows Delthea 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. This is fitting if you chooe to inherit Life and Death or Desperation onto her. Her low Def is of less importance, so it is safe to take Def as a bane.

Delthea Best Weapon Refinement

Effect of Delthea's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Dark Aura	SP: 400
Might: 14　Range: 2　HP: At start of turn, if adjacent allies use sword, axe, lance, dragonstone, or beast damage, grants Atk+6 to those allies for 1 turn. If unit is within 2 spaces of a sword, axe, lance, dragon, or beast ally, grants Atk/Spd+5 to unit during combat. ：500　：200

We recommend the Special Effect Refine for Dark Aura

Dark Aura's original effect only grants Delthea's allies the bonuses. With the special effect refine, Delthea gets bonuses through a same trigger condition as well! This is a must get if you plan to use Delthea in the long run. A +5 Atk/Spd in both phases can not be ignored. With more investment, she will become a very reliable offensive unit.

Delthea Roles, Strengths, and Weaknesses

Delthea Roles

Delthea - Free Spirit 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

Delthea 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.

Delthea Strengths

Grants a massive boost to melee heroes

Dark Aura grants +6 Atk to melee heroes if they are adjacent to Delthea at the start of a turn. That is a wide range of units that Delthea can apply buffs on. This makes her versatile and able to easily fit in many types of line-ups.

This weapon also has access to a special effect refine that provides Delthea with some offensive buffs too!

Can buff allies' Atk

Delthea's C Skill Drive Atk 2 will give a +3 Atk buff to her allies within 2 spaces. This lets her support allies just by being nearby, and equipping her with the Sacred Seal Drive Atk 2 or Spur Atk 3 can further increase the effects of this bonus.

Miracle can prevent her from being taken out

Her native special skill, Miracle, has a long cooldown but it saves her from an attack that will take her out. This can buy your team the opening to take out that enemy and save Delthea for many turns to come.

Delthea Weaknesses

Low Def

Delthea's Def only sits at 17 at Lv.40. This makes it easy for physical units to take her out. Be mindful of Delthea's positioning in relation to physical units that can easily take her out.

Her weapon cannot buff ranged units

Dark Aura cannot buff ranged units. This makes her an iffy pick when building ranged-heavy lineups. Keep this in mind when building teams around Delthea!

Delthea as a Source Hero

Inheriting Drive Atk 2

Delthea can be used to inherit the skill Drive Atk 2. Before fodderring off Delthea for this skill, keep in mind that Drive Atk 2 is also available as a Sacred Seal. Another thing to keep in mind is Delthea is a 5★ exclusive. If you badly need this skill, check first if you have the more common Echidna as Drive Atk 2 is available from her at 4★.
