Key stats worth increasing through nature if possible.
Complementary stats that matter, but not to the point of picking them over key stats for nature increase.
Relatively worthless stat that can safely be decreased through nature.


  • +SPD: Like most other offensively oriented mages, Delthea benefits substantially from receiving a Speed Asset to supplement her already formidable combat prowess through a greater likelihood of performing and denying follow-up attacks against opposing foes.

  • +ATK: An Attack Asset is also a great choice of IVs to heighten her raw damage output, elevating her strong base Attack stat of 36 to an incredible value of 39. In particular, this Asset pairs especially well with offensive builds aiming to maximize Delthea’s ability to consistently OHKO her opponent.

  • +RES: Although generally less preferable than either of the aforementioned options, Delthea can potentially make good use of a Resistance Asset to focus strictly on augmenting her supportive capabilities when equipped with Dark Aura, strengthening her ability to reliably make use of Ploys and Sabotage skills to provide a potent mix of buffing and debuffing utility.


  • HP: Delthea’s HP can be left at neutral to preserve her decent amount of magical bulk, however, it can still be a suitable choice of Flaw should no other option be available.


  • -DEF: At an abysmal base value of 13, Delthea sports the lowest Defense stat in the entire game as of the time of writing, making her liable to be easily OHKO’d by any kind of physical damage. Accordingly, she can safely take a Defense Flaw without repercussion as lowering it further will hardly affect her overall performance.

Show Explanation/Analysis

Preferred IV: +ATK or +SPD or +RES -DEF

This build sees Delthea taking a primarily support focused role but thanks to the power of refined Dark Aura, she can still remain a reasonably powerful combatant to her own right. Accordingly, an Asset to either her Attack or Speed stat can be taken to build upon her offensive capabilities, though a Resistance Asset may prove to be equally as useful to bolster her proficiency at utilizing Ploys and Sabotage skills for additional utility.

Weapon: Dark Aura (+Eff)

  • Delthea’s unique personal weapon, Dark Aura, provides her with potent, albeit somewhat limited, supportive capabilities and grants any adjacent melee allies with an impressive +6 Attack buff -- and what’s more, its unique weapon refinement allows her to also benefit from an increase to her offensive potential simultaneously, letting her gain a stellar +5/+5 Atk/Spd in-combat boost when nearby such allies.

  • This combination of effects gives her immense flexibility in relation to the role that she can fulfill in any given team, requiring only that she have at least one melee ally alongside her in order to truly maximize her overall potential.

Assist: Reposition / Flexible

Special: Glimmer / Moonbow / Draconic Aura

  • Glimmer and Moonbow are both excellent choices for her Special thanks to their extremely low cooldown allowing her to make use of them quite frequently. The decision as to which to utilize is largely up to personal preference, with Glimmer scaling well with her typically high damage output and Moonbow faring better against particularly bulky foes who she would otherwise struggle to dent.

  • In exchange for longer cooldown, Delthea’s native Draconic Aura can be kept for its stronger consistency and overall damage potential.

Passive A: Fury / Fort. Def/Res / Atk/Spd Solo / Swift Sparrow / Death Blow

  • Fury (3 or 4) is Delthea’s ideal choice of A slot skill, greatly appreciating its overall stat boost to gain a decent increase to her combat prowess as well as a lesser chance of being OHKO’d outright by an opponent’s counterattack. It also has the additional benefit of giving her better odds of being able to activate Ploys and Sabotage skills against the opposing team.

  • Alternatively, one can take Fortress Def/Res to dramatically heighten her overall bulk and similarly enhance the way in which she can provide support to her allies. This does, however, come at the cost of restricting her offensive capabilities quite substantially as the skill essentially does nothing to boost , though it does detract from her healing slightly with its additional effect of -2 Attack.  

  • Should one wish to focus solely on capitalizing on Delthea’s offensive potential, Atk/Spd Solo and Swift Sparrow are excellent candidates here as well, providing her damage output and ability to perform follow-up attacks with a dramatic improvement.

  • Her native Death Blow can be kept on a budget, but do keep in mind that it will force her to take a more OHKO-dependent playstyle.

Passive B: Sabotage Atk / Chill Atk / Chill Spd / Desperation / Flexible

  • Delthea’s solid base Resistance stat of 31 allows her to make reasonable use of Sabotage Atk to further her ability to support her teammates and potentially inflict a devastating -7 Attack debuff on multiple foes at once -- and unlike Ploy skills, Sabotage Atk can be active at all times of the battle regardless of Delthea’s positioning, granting her fantastic coverage provided that she can maintain reasonable levels of Resistance.

  • Chill skills perform comparably to Sabotage skills, however, they differ in that while Sabotage skills possess a greater likelihood of debilitating multiple foes, Chill skills are guaranteed to target at least one opponent, making them arguably more consistent options depending personal preference. The choice over which Chill to utilize should ultimately boil down to a matter of skill availability as well as which best complements her chosen team composition.

  • For a purely offensive approach, Desperation will be ideal as it allows her to freely perform follow-up attacks and engage in extended rounds of combat without worry of being killed in retaliation.

Passive C: Joint Hone Spd / Ploy Skill / Drive Atk / Flexible

  • Joint Hone Spd is a wonderful choice of C slot skill thanks to its immense synergy with refined Dark Aura, granting any adjacent melee allies with a huge boost to both of their offensive stats while also bolstering Delthea’s own offensive presence.

  • Ploys can be considered as well and can activate quite reliably thanks to her good base Resistance. Of those available to her, Atk Ploy and Spd Ploy possess the most overall applicability but like her choice of Chill or Sabotage skill, the choice of which Ploy to use will largely depend on what her specific team composition consists of.

  • Otherwise, feel free to make use of any available C slot skill here, with her native Drive Atk being a strong pick to stack additional Attack buffs on top of the ones provided by Dark Aura.

Sacred Seal: Drive Atk / Ploy Skills / Tactic Skills / Heavy Blade / Darting Blow / Atk/Spd 2

  • Delthea’s seal slot is quite flexible; any choice of Drive, Ploy, or Tactic skill will work perfectly to add on to her supportive capabilities.

  • Conversely, the Heavy Blade seal can be taken to increase her own damage output through more frequent Special activations -- and thanks to her combination of a high Attack stat and Dark Aura’s refined effect, Linde will be able to activate Heavy Blade with relative ease.

  • Lastly, the Darting Blow, Speed +3, Attack +3, and Atk/Spd 2 seals are always solid choices to improve her ability to perform as a capable combatant.

Show Explanation/Analysis

Preferred IV: +ATK or +SPD / -DEF

Given this build’s primarily offensively oriented approach to Delthea’s playstyle, an Asset to her Attack or Speed stats make for her ideal choice of IVs here to build upon her already formidable offensive presence. Of the two, a Speed Asset is generally the preferable option to let her perform follow-up attacks more reliably and maximize her damage output, but both are ultimately fantastic choices.

Weapon: Blárblade+

  • Blárblade allows Delthea to make the greatest use of her exceptional offensive stat spread and attain an incredibly high damage ceiling. Conversely, however, it also makes Delthea exceedingly more reliant on team support to function properly, necessitating that she be accompanied by allies who can provide her with field buffs in order for her full potential to be achieved.

Assist: Reposition / Ardent Sacrifice / Flexible

  • Delthea’s low overall bulk can make reaching Desperation’s HP threshold safely without being KO’d somewhat of a challenge. Accordingly, one can take Ardent Sacrifice as her chosen Assist to instantly drop her into the threshold with a single use.

  • Otherwise, any Assist of one’s choosing may be used here, with movement Assists like Reposition always remaining good options.

Special: Glimmer / Draconic Aura

  • Glimmer’s low Special cooldown as well as its ability to scale incredibly well with the additional damage granted by Blárblade’s effect makes it the prime choice of Special for any Blade tome user, and Delthea is no exception. It also has strong synergy with the Heavy Blade seal to ensure its activation in her first round of combat provided that she performs a follow-up attack and her opponent counterattacks, further increasing its viability.

  • Delthea’s native Draconic Aura can be taken to provide her with a much stronger damage boost upon Special activations in exchange for longer cooldown, but this can easily be bypassed via the use of the Heavy Blade seal as well.

Passive A: Atk/Spd Solo / Swift Sparrow / Fury / Death Blow / Life and Death / Brazen Atk/Spd

  • Atk/Spd Solo is a powerful skill that lends itself well with this build’s intended playstyle, offering her a dramatic +6 in-combat boost to her offenses without sacrificing her overall bulk. Although it does require that she have no adjacent allies in order to benefit from its effect, the fact that Delthea will typically be away from her allies when initiating combat regardless means that its positioning requirement will be a non-issue in most scenarios.

  • Should it be unavailable, Swift Sparrow makes for a great substitute to similarly augment her offensive potential through its considerable, albeit weaker, +4/+4 Atk/Spd in-combat boost upon initiation.

  • Fury remains a good option as well to decrease her chances of being outright OHKO’d by opposing foes in addition to giving her offenses an appreciable boost concurrently.

  • Particularly if making use of an Attack Asset, Death Blow (3 or 4) can be considered to maximize her ability to OHKO her opponent through its massive boost to her raw damage output.

  • If using Ardent Sacrifice as her chosen Assist, Life and Death (which carries the additional demerit of disallowing the use of Ploys entirely) and Brazen Atk/Spd become available options as they are otherwise far too risky and inconsistent.

Passive B: Desperation / Chill Res / Sabotage Res

  • Desperation is a crucial component of this build, being of the utmost necessity in order to bypass her low overall bulk and allow her to freely engage in extended rounds of combat without having to worry about being killed in retaliation.

  • Alternatively, Delthea can take Chill Res or Sabotage Res as her chosen B slot skill to improve her match-ups against high Resistance tanks who could otherwise prove to be a nuisance and solidify her formidable OHKO capabilities.

Passive C: Odd Atk Wave / Even Spd Wave / Drive Atk / Flexible

  • Odd Atk Wave and Even Spd Wave are two particularly noteworthy C slot skills that allow her to be much more self-sufficient, as well as enable her to potentially provide team support on odd and even-numbered turns respectively.

  • Such skills are not strictly necessary in order for the young mage to function properly, however, and can simply be replicated by providing her with team support. Accordingly, if unavailable, any available C slot skill like her native Drive Atk may be used instead.

Sacred Seal: Heavy Blade / Darting Blow / Atk/Spd 2 / Speed +3 / Attack +3

  • As previously mentioned, the Heavy Blade seal has fantastic synergy with this build, providing Delthea with the means to skyrocket her damage output through faster (and deadly) Special activations.

  • Should the Heavy Blade seal already be taken by one of her allies, the Darting Blow, Atk/Spd 2, Speed +3, and Attack +3 seals (or any of their variants) remain good alternative options to supplement Delthea’s offenses further.


The magical prodigy Delthea makes her way into Fire Emblem Heroes sporting a formidable mix of unique strengths that enable her to perform as one of the more versatile infantry mages around. Statwise, she boasts excellent values in Attack and Speed, making her a reliable source of damage output, especially when capitalized on through the use of a Blade tome. Her base Resistance stat of 31 is quite decent as well and lets her make good use of Ploys and Sabotage skills to support her allies through debuffing support. Delthea’s main differentiator from other blue infantry mages, however, is her unique personal weapon, Dark Aura. With its unique ability to simultaneously enhance both her and fellow melee allies’ overall performance tremendously, refined Dark Aura allows Delthea’s role to be immensely flexible as she can easily alternate between performing as a dedicated support unit and capable combatant throughout the course of a given battle.

It should be noted, however, that despite these strengths, Delthea is also in possession of clearly-defined weaknesses, most notable of which being her markedly poor physical bulk. Boasting the honor of having the lowest base Defense stat in the entire game as of the time of writing in addition to a relatively unimpressive HP pool, Delthea is incapable of taking on most forms of physical damage directly and will often have to rely on skills such as Desperation to avoid otherwise deadly counterattacks. Additionally, regardless of the weapon she is utilizing, her team composition will face some restrictions, albeit not necessarily severe enough such that they heavily detract from her overall usefulness -- Dark Aura is only effective when deploying her alongside melee allies and Blárblade necessitates that her teammates to carry field buffs in order for her to function properly. Nonetheless, Delthea remains a solid unit to her own right and can prove to be a valuable asset at one’s disposal when utilized properly, simply requiring the proper conditions and right team composition to do so.


Dark Aura

Delthea’s unique tome, Dark Aura, is a potent personal weapon that allows her to function as a potent buffer to melee allies as well as perform as a reasonably powerful combatant at the same time. When combined with her complementary base stats, this weapon differentiates her as one of the more versatile mages around, capable of fulfilling both of the aforementioned roles quite well.

Strong Offenses

Delthea’s neutral offensive spread of 36/34 is sufficient enough such that she can perform as an excellent (and consistent) source of damage output on any given team, especially when given the proper support and investment.

Good Resistance 

Delthea’s base Resistance stat of 31 allows her to function as a reliable user of Ploys and Sabotage skills which can be used to enhance both her and her allies’ overall performance.


Thanks to the advent of Dark Aura’s weapon refine, Delthea possesses a unique mix of offensive and supportive utility, making her an exceedingly versatile ally as her role can easily  fluctuate throughout the course of a given battle depending on what is needed of her.


Exceedingly Low Physical Bulk

Delthea’s combination of abysmal Defense and a poor HP pool renders her exceptionally weak to any form of physical damage and makes it pivotal that she be kept out of harm’s way from physical attackers, else she risks being flat out OHKO’d by such foes.
