When equipped to Mordred,
Increase NP Damage of all allies by 20% while she's on the field.

Table of Contents


The illegitimate child of Altria Pendragon, Mordred enters Chaldea fulfilling the same niche as her father. With good base attack stats, a Buster AoE NP, and a Buster performance buff, Mordred is built for clearing waves and a good choice for farming. She can also charge her NP by up to 30% with her Secret of Pedigree, making it easier for her to get her NP ready. This same skill also provides a sizable defense buff and debuff cleanse, which combined with her high hp allows her to fulfill an offtank role. Finally, her NP deals additional damage to any Altria-type enemies, making her a bane to the Lancer-class Altrias. 

However, outside of her main niche as a farmer, Mordred suffers from the same weaknesses as her father. Her NP gain is mediocre, making it difficult for her to even get that first NP off without support Servants or CEs.  Though the NP refund Mordred gets from using her NP is good, it’s a non-factor if she can’t even use it. Her anti-Altria niche is also too specific, especially considering she only has two effective targets in the Lancer class. Overall, Mordred can be effective with the right team and CEs, but her vanilla skillset doesn’t do her any favors.


Strong AoE NP

Mordred has relatively high attack stats, as well as a Buster performance buff. These two aspects allow her to deal good AoE damage, making her a great choice to clear waves or for farming. The fact that she can charge her NP by up to 30% via Secret of Pedigree also helps her with this niche. Her NP also refunds some NP after use, so it gets slightly easier to charge it a second time.

Decent Survivability

Sporting a good amount of HP, as well as a debuff and defense-increasing skill, Mordred can be survive longer than most Servants. As a result, she can possibly cast her NP multiple times in a battle.

Anti-Altria Niche

A very specific niche, but a niche nonetheless. Mordred can easily deal with both Altria Pendragon Lancer and her Alter version due to the bonus damage from her NP. She can also be used against Altria’s Saber versions, but it’s not optimal.


Low NP Gain

With her Buster-centric kit (though she does have two Arts cards) and her mediocre NP gain, Mordred has to rely on support Servants or CEs to get her NP charged up. Her NP refund and NP-charging skill make up for this slightly but not enough to enable her to reliably spam out her NP.

Vanilla Skillset and Kit

Mordred can be comparable to Altria in terms of her kit in that she has a general skillset and relies on her Buster AoE NP. However, in contrast to Altria, she replaces team support with a self NP charge and defense up, making Mordred a little more selfish, if not a better farmer.

Level Up Skill Recommendation

  • Mana Burst ideally should be prioritized as it synergizes the best with Mordred’s main niche, her massive AoE Buster damage.
  • Secret of Pedigree should follow afterwards, mainly because it charges Mordred’s NP, allowing her to more quickly use it. The defense up and self-debuff removal are also great secondary effects and will help Mordred be more durable.
  • Intuition should be saved for last. At maximum, it only gives 14 stars which is a rather low amount. Although Instinct may  lead to some clutch criticals, outside of CEs and support Servants, Mordred doesn’t really have a reliable way to collect the stars she just created.

Craft Essence Recommendation

  • Kaleidoscope/ The Imaginary Element: With the help of Mordred’s third skill, she can near-instantly (or instantly depending on the skill level) charge her NP gauge to full, allowing her to use it immediately. Perfect CE for farming. 
  • Limited/ Zero Over/ Verdant Sound of Destruction: Given Mordred’s main Buster damage niche, these CEs will help her increase her damage all the more.
  • Halloween Princess/ Heaven’s Feel/ The Black Grail: Mordred’s AoE NP damage will further be increased when equipping these CEs, perfect for her main niche. Halloween Princess deserves a special mention as it also charges her starting NP.
  • Golden Sumo: The attack buff this CE brings is different from the buffs Mordred has, allowing it to stack multiplicatively instead of additively for more damage. It also synergizes well with her kit in general as it allows her to deal more damage outside of her NP.
