Overview

“I am not an Assassin. I am definitely a Saber.”

In a Servant-verse far far away, Mysterious Heroine X has taken up the noble duty of exterminating all Sabers. Outside of an extremely narrow niche in destroying all Saberfaces, MHX is a Quick Assassin with very impressive bases, yet one that suffers under a very underwhelming set of skills. 

Indeed, much of MHX’s potential lies in the base performance of her 4-hit Quick Cards and 12-hit upgraded Quick Noble Phantasm. With her good base NP Gain and Riding EX, her Quick cards not only produce a tidy sum of Critical Stars, they also produce a great amount of NP Gauge as well as refund potential on NP. As such, with proper Quick support, MHX becomes capable of launching her upgraded NP in rapid succession. In addition, after her Rank Up, she is rather durable considering she carries both an Invincibility on a 5-turn cooldown as well as an 80% of landing an AoE Stun. Finally, she does have a small niche in disposing of loathsome Saberfaces regardless of their class through the Overcharge on her NP.

Unfortunately, MHX’s skill set does not mirror the strength of her generation performance. Galactic Meteor Sword’s performance boost against Sabers is very narrow in its use, and any Archers will see a much larger performance boost from the effects of class advantage. Meanwhile, her Fire Support carries a massive 8 turns of cooldown at max rank in addition to its only 80% chance to hit. As a result, with no room in her skills left for general steroids, MHX’s damage performance without support is on the low side, having only her NP Interlude and Riding EX to draw on. 

Thus, MHX ends up being a very solid Servant but because her niche is too niche, she is never truly the top option for any Assassin-related job. Even then is often outclassed by competing Assassin options when tackling her niche, such as Jack’s female bonus versus Saberfaces. Yet, her base performance is very strong and Masters should not underestimate the value a strong Quick Support can do to compensate for her skill set.

With all of her most important aspects unaffected by her skills, Masters can elect to leave leveling her skills for later when any pressing Ascension Material needs are taken care of. Still, Star of Saber is a great skill, and Masters are at least highly encouraged to try and maximize it. 

• Fire Support EX carries a massive 10-turn cooldown at base. Thus, even with additional levels, there are very few situations in which this skill can be used more than once. In addition, the stun chance doesn’t scale very well. Level this last. 

• Star of Saber C++ is MHX’s stand-out skill post-Rank Up, carrying both a short cooldown Invincibility, and an actually impactful number of Instant Critical Stars. Level this first mainly for the cooldown reduction, and at least to level 6. 

• Galactic Meteor Saber C contains MHX’s Anti-Saber potential. However, unless Masters lack a strong Archer option, it’s not truly worth fielding MHX to deal with Saber enemies. Still, the benefits of leveling this if MHX is fielded in a mixed enemy node aren’t entirely bad, so Masters can level this second. 

Craft Essence Recommendation

Imaginary Around

Dumplings Over Flowers

Cute Orangette

Magical Girl of Sapphire

Little Halloween Devil

Golden Sumo: Boulder Tournament

Knights of Marines

Holy Night Supper

The Black Grail

Most offensive Craft Essences work well with MHX, but both Quick Performance Up and NP Gain Up stand out. Both of these effects improve her ability to unleash successive NPs, and while Quick Performance grants the most versatile boost to her performance in isolation, NP Gain works best if MHX is fielded with a powerful Quick Support. NP Damage Up, Critical Damage Up, Starting NP Gauge, and Attack Up are all very viable alternatives though. 

Note: NP Damage Up and Critical Damage Up stack additively with her Anti-Saber buff, but multiplicatively with her Anti-Saberface buff. Thus avoid those options vs Sabers. 

• Imaginary Around/ Dumplings over Flowers: Quick Performance CEs are always a safe choice, especially during longer encounters. 

• Cute Orangette / Magical Girl of Sapphire / Little Halloween Devil: Variations on NP Gain CEs work best in compositions with Quick buffs as NP Gain stacks multiplicatively with Card Performance buffs. Make sure the stat budget is allocated to Attack though.

• Golden Sumo / Knight of Marines / Holy Night Supper: Golden Sumo stacks best with the various effects in MHX’s kit, but any of these hybrid CEs work well for shorter quests.

• The Black Grail: For the strongest possible damage output, and with immense support, The Black Grail reigns supreme.
