Attack / HP Growth


The eldest of the three gorgon sisters, Stheno is an anti-Male specialist of the Assassin class. She is one of the most extreme Servants when it comes to specialized kits, touting a Buster NP that does no damage and cannot be Buster-Brave chained. Instead, her NP can inflict Instant Death (on Males only), Charm (on Males only), and a defense down debuff. For non-male enemies, her NP essentially becomes only a defense down debuff, which other Servants can accomplish with additional effects. Her second skill’s charm is also Male only. In essence, bringing Stheno to a quest without male enemies renders much of her kit ineffective.

However, against male enemies, she can render them helpless for turns on end. In addition to her charms, her first skill enables her to drain the opponent’s NP charge and fill her own NP gauge. She also has one of the highest NP gains in the entire Servant pool, enabling her to fire off her NP in rapid succession. After Stheno’s Rank Up, she receives a powerful Charisma skill that gives additional bonus attack to Servants with the Divine attribute (quite common among the cast), increasing her supportive effectiveness in parties tremendously. With it, she becomes a good choice as a damage support for divine Servants once unlocked.

Overall, Stheno is a unique and very niche anti-Male Servant with great stats whose usage is limited, but is slightly broadened with her Rank Up, adding a role for her as a support for Divine attribute comrades.


Powerful Anti-Male Skills

Her second skill along with her NP are capable of locking male enemies in a charm state for a long time.

High NP Gain

She has one of the best NP gains in the entire game, allowing her to spam her NP near-constantly if the card draws line up properly.

Immense Debuff Resistance

Core of the Goddess combined with her Magic Resistance grants her exceptional debuff resistance, with a total of 50% debuff resistance at baseline.

Divine Attribute ATK Buff

With her Rank Up quest, she will have one of the highest ATK buffs available for Servants that have the Divine attribute (total +40% ATK for Divine allies including herself, +20% for other allies), making her a great damage support to use in the party.


Assassin-class Damage

The Assassin-class 0.9x damage multiplier, an overwhelming sum of Quick cards, and a non-damaging NP makes her offensive power rather pitiful.

Niche Usage

When pitted against non-Males, one of her skills is essentially useless while her NP turns into a simple defense down. Additionally, her younger sister Euryale is a direct competitor that outperforms her in many of these situations. Rider-class Male enemies where she can exercise class advantage in conjunction with her anti-Male role are few and far between.

Inconsistent Effects

Even when fighting Males, Instant Death is an incredibly inconsistent effect which essentially never works versus the difficult enemies which it would be useful for. Also, her second skill’s Charm effect may miss due to enemy Magic Resistance, even if maxed.

Craft Essence Recommendation

OVERALL: Stheno’s main goal is the keep the enemy charm-locked, and her (Quick) command cards are her main source of damage. Quick Up / NP gain / C Star Drop Rate Up / C Star Regen per turn / Debuff Success Up craft essences work well with her.

  • Imaginary Around / Gandr: These give Quick performance buffs, which is the primary source of her damage.

  • Divine Banquet / Little Halloween Devil / Beasts Under the Moon: All of these provide additional NP gain, some of which provide some additional bonuses that help improve other aspects of performance.

  • Kitchen Patissiere / Moonlight Fest: Provides C Star Drop Rate bonuses, along with either an NP gain bonus or critical attack damage bonus depending on your preference (or CE availability).

  • A Fragment of 2030: The staple craft essence for C. Stars per turn.

  • Burning Tale of Love / Record Holder / Elixir of Love: These CEs enhance the success rate for her debuffs (such as Charm), which help the consistency of her charm-lock skills. The first CE, Burning Tale of Love, also enhances damage dealt to Male enemies, making it a great CE to run on any anti-Male Servant.

Level Up Skill Recommendation

Vampirism C: Levels in Vampirism increase the amount of NP gauge granted by this skill, in addition to increasing the likelihood of NP charge drain success. This skill is useful in enabling her to use her NP more quickly, while boosting her consistency in stalling.

Siren Song A: Points in this skill are useful for increasing the consistency of her Charm (up to 100%, although this can be reduced by enemy Magic Resistance). Although this skill is more niche, and can be left for last, increasing the likelihood of Charm success is still useful to her performance as an anti-Male Servant.

Whim of the Goddess A (Stheno): Unlocked after her Rank Up quest, this skill grants an attack buff to the whole part equivalent to Charisma A (20% at max), with an additional equal buff to Divine attribute allies (20% at max, totaling at 40%). This skill is the most flexible among her skillset, and is worth leveling first.

Suggested Servant Synergies

  • Orion: Orion is another part of the anti-Male squad. Stheno can stall the enemy with her NP battery/drain and charm along with Orion’s NP drain (which is now guaranteed with her NP interlude). Her NP has decently high uptime due to good arts gain from Stheno’s Caster Animation, but is pretty much reliable only as another charm on male enemies, plus a defense down. On a side note, with Euryale added to the party, it is possible to a anti-Male charm-lock team, as proven with a no damage taken run against Dantes in the Chateau d’If event.

  • Euryale: The final addition to the Gorgon Sisters, she completes the anti-Male squad of Stheno, Orion, and Euryale. She also shares a Charm and NP battery/drain skill with Stheno, and Charm tied to her NP. She also contributes good damage with her ST Arts NP, which has a flat bonus multiplier against Male enemies. With this team against a single Male enemy, it is completely possible to configure your skill rotation such that he's so spellbound he never gets a chance to move!

  • Vlad III: Vlad and Stheno can use their vampirism skill for NP stalling while simultaneously building their NP gauges. Although Euryale’s NP and charm are pretty much only usable against males, she can provide a decent amount of stars for Vlad to get him rolling with Kazikli Bey, and indirectly her NP chain will boost Vlad’s damage and help him gain more stars from overcharge. Honorable mention also goes to Carmilla, who can also use Vampirism, and benefits from additional damage versus females with her NP.

  • Mata Hari: Mata Hari’s charms add another layer to Stheno’s dual charms, and together they can do a charm-stall debuff sort of deal. Both have charms as skills and NP’s, leading to potentially 4 charms. Meanwhile, both can take advantage of the debuffs.
