Legendary Deirdre Skills at 5★

Spirit Forest Writ Might: 14　 Range: 2 Accelerates Special trigger (cooldown count-1). Effective against dragon foes. If unit is within 3 spaces of an ally, inflicts Atk/Res-6 on foe during combat, unit makes a guaranteed follow-up attack, disables foe's skills that "calculate damage using the lower of foe's Def or Res," and also, if unit's Res > foe's Res at start of combat, inflicts penalty on foe's Atk/Res during combat = 80% of difference between Res stats at start of combat. (Maximum penalty of -12.)

Circlet of Balance Cooldown Count = 2 Boosts Special damage by 40% of unit's Res. If unit's HP > 1, foe would reduce unit's HP to 0, and both following conditions apply, unit survives with 1 HP: ・ Unit or foe's Special is ready, or unit or foe's Special triggered during this combat. ・ Unit initoates combat or foe's Range = 2. (Once per map. Considered a non-Special effect. Does not stack with non-Special effects that allow unit to survive with 1 HP if foe's attack would reduce HP to 0.)

Still Water 4 Grants Atk/Res+7. Inflicts Def-5.

Atk/Res Tempo 3 Inflicts Atk/Res-3 on foe and neutralizes effects that grant "Special cooldown charge +X" to foe or inflict "Special cooldown charge -X" on unit during combat.

Atk/Res Menace At start of turn, inflicts Atk/Res-6 on nearest foes within 4 spaces through their next actions and grants Atk/Res+6 to unit for 1 turn.

Legendary Deirdre Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★☆☆
Atk (13)		★★★★★
Spd (6)		★★★☆☆
Def (4)		★☆☆☆☆
Res (10)		★★★★★

◯ = 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.

+Atk / -Def

The best IVs for Legendary Deirdre are +Atk and -Def. Her Atk is very high at base 43 and increasing it improves her prowess as a heavy nuker unit.

Her Def is a clear dump stat, especially with Still Water 4, and should be the bane of choice.

+Atk for a +10 merge

We recommend a +Atk IV when merging Legendary Deirdre to +10. Increasing Atk leads to the best performance.

+Spd is also an option when opting to Spd stack Legendary Deirdre in order to compete with other above average Spd heroes.

Legendary Deirdre Roles, Strengths, and Weaknesses

Legendary Deirdre Roles

Deirdre - Fated Saint 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

Legendary Deirdre 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.

Legendary Deirdre Strengths

Spirit Forest Writ is an amazing weapon for both offense and defense

Legendary Deirdre's Spirit Forest Writ is a powerful blue tome that has in-combat effects and stat swings that all help her win in combat.

Below is a summary of these effects:

Condition(s)	Effect
Always	Accelerates Special trigger (cooldown count-1).
Always	Effective against dragon foes.
Legendary Deirdre is within 3 spaces of an ally	Inflicts Atk/Res-6 on foe during combat.
Legendary Deirdre is within 3 spaces of an ally	Legendary Deirdre makes a guaranteed follow-up attack.
Legendary Deirdre is within 3 spaces of an ally	Disables foe's skills that apply adaptive damage.
Legendary Deirdre is within 3 spaces of an ally Legendary Deirdre's Res > foe's Res at start of combat	Inflicts penalty on foe's Atk/Res during combat = 80% of difference between Res stats at start of combat. (Maximum penalty of -12.)

Circlet of Balance deals high damage quickly and grants survivability

Legendary Deirdre's Circlet of Balance is a 2 cooldown Special (1 after Spirit Forest Writ) that boosts her attack by 40% of her Res.

It also grants a once per map Miracle effect if certain conditions are met. In order to trigger this effect:

• Legendary Deirdre must either initiate combat, or be in combat against a ranged foe.
• A Special skill (either Legendary Deirdre's or her foe's) must either be ready or triggered during combat.

Even without the Miracle effect, Circlet of Balance is a 1 cooldown mini-Iceberg, and with Legendary Deirdre's sky high Res stat, this will deal heavy damage often.

Legendary Deirdre Weaknesses

Abysmal Def

Legendary Deirdre's base Def sits at 19, which is further lowered by Still Water 4 if you choose to keep it equipped. This leaves her completely vulnerable to opponents that deal physical damage, especially melee foes that can partially avoid the conditions of Circlet of Balance.
