There are very few Servants in the game that can boast potency in both farming and boss slaying, but Minamoto-no-Raikou can easily do both with her overloaded skillset and fantastic firepower. She fills a similar role as Lancelot (Berserker), but Raikou is several magnitudes more potent than Lancelot in anything he can do, making her one of the most versatile damage dealers in the game.

Thanks to her Berserker class and AoE Noble Phantasm, Raikou is one of the strongest farmers in-game because she will deal class advantage damage against most enemies. On the other hand, her single target offensive capacity is no slouch either; her Mana Burst (Lightning) and Eternal Arms Mastery allow her to be a reliable  Buster Critical Damage Dealer Berserker, a very rare but powerful niche in the current state of the game that will only be even more ludicrous in the future.

What separates Raikou from her peers is her third skill: Mystic Slayer, which boasts immense coverage over a large roster of possible enemies and lasts for 3 turns. She is extremely capable of operating in any balanced or offensive team, as her kit already grants her all the tools she needs to do the job. A common way to utilize her is to use her Noble Phantasm on a wave with 3 enemies prior to facing a boss in order to to grant her a large influx of Critical Stars, and then decimate said boss the next turn with her guaranteed Critical Attacks boosted by Mystic Slayer.

That being said, Raikou is definitely not without weaknesses. Being a Berserker, her survivability is much lower than other classes. While her Mana Burst (Lightning) does offer her a one-turn dodge, it is also tied to her card performance self-buff, meaning there will be a potential trade-off and big opportunity cost tied to this skill. Furthermore, Raikou lacks a strong Critical Damage buff, often relying on teammates and Craft Essences to provide this for her. Last but not least, Raikou’s performance often heavily depends on her Noble Phantasm to get her Critical Stars if the team cannot provide them for her, which limits the options when crafting a dedicated team around her.


Amazing farming potential

Being an AoE Berserker, Raikou’s general AoE Damage output is extremely potent, further boosted by her wide coverage against enemies with Divine/Mystery trait. She is one of the best general farmers in the game, capable of putting a dent into any enemy with her class’s bonus damage.

Extremely reliable Buster Critical Damage Dealer

Eternal Arms Mastery grants Raikou a reliable way to absorb Critical Stars. With the ability to also generate Critical Stars from her Noble Phantasm, strong basic card damage, wide anti-trait coverage, Berserker class advantage, and a Buster Brave Chain, Raikou is one of the best single target damage dealers in the game as well. She holds a niche that is not just very powerful, but also extremely rare.

High damage output on basic cards

Even when she is not doing Critical Damage, Raikou’s basic cards have quite high and stable damage output. She is amplified by a large amount of passives (Divinity, Ex Ranked Mad Enhancement, Riding) and actives (Prana Burst Lightning, Mystic Slayer) which are highly overloaded compared to standard Servants. Furthermore, she boasts a very balanced deck with BBAAQ and the ability to do Buster Brave Chains with her NP for a massive damage burst.

Capable of generating a large amount of Critical Stars with her Noble Phantasm

Vengeful Lightning of the Ox-King does not just deal good damage, it also grants her an absurd amount of Critical Stars when used correctly. This allows Raikou to be more self-sufficient than other Critical Damage Dealers and generate Critical Stars on her own.


No Long-term Survival:

At the end of the day, Raikou is still a Berserker. Even with an on-demand dodge tied into her Mana Burst (Lightning), her survivability is still quite sub-par. Any team looking to build around her must account for this heavily detrimental aspect of her, as without protection it is not rare to see her drop at a moment’s notice.

Lacks of strong Critical Damage buff

While the amount of self-buffs on Raikou is hardly insufficient, she does not have a strong Critical Damage buff, which is essential to her role as a Critical Damage Dealer. This can be solved with support from teammates such as Andersen or Zhuge Liang though, or Craft Essences such as Victor from the Moon.

Level Up Skill Recommendation

It is highly recommended to max all Raikou’s skills as soon as possible, as they are all fantastic and vastly improve her performance.

  • Eternal Arms Mastery is already quite potent at level 1, and rarely do teams generate enough Critical Stars over a consistently long period without heavy investment (with Fragments of 2030). Thus levelling it last won’t hurt Raikou’s performance significantly. If the team can protect Raikou however, this skill can be maxed over Mana Burst (Lightning) for more reliability in gathering Critical Stars
  • Mana Burst (Lightning) is both her steroid for her Noble Phantasm as well as her sole survivability tool. While the value of the buff isn’t as strong as other Mana Burst skills, it is still an amazingly useful skill thanks to its dual purpose and versatility. Lowering the cooldown of this skill can make Raikou last much longer on the battlefield, and improve her damage output by quite a bit.

  • Of her skills, Mystic Slayer is her most important skill, as it scales extremely well with levels. Furthermore, it lasts over 3 turns, granting her one of the most consistent and ridiculous steroids in the game.

Craft Essence Recommendation

Critical Damage Up:

  • Victor of the Moon: Adding critical damage takes advantage of Raikou’s Star Absorption, and the bonus to Buster performance is always relevant to her. Furthermore, this Craft Essence has one of the best Attack bonus values possible in the game.

  • Gem Magecraft: Antumbra: Grants her an extremely sizable Critical Damage increase, on top of a strong Attack bonus.

  • Guda-O: This Craft Essence grants her two buffs she lacks in her kit, which are Critical Damage and NP Damage bonuses. It is also an event Craft Essence with its stats solely focus on Attack, making it the perfect addition to Raikou’s repertoire.

Starting NP:

  • Golden Sumo: One of the best Craft Essences on Raikou. The starting NP and passive bonus attack increase synergize incredibly well with her role.  

  • Kaleidoscope / Imaginary Element / Halloween Princess: For pure farming purposes, very few Craft Essences are more well-suited than these three.
