The Best Ruan Mei Build Guide In Honkai: Star Rail

If you’ve been playing Honkai: Star Rail for a while, you most likely know how broken the characters from the Harmony Path are. The four-star characters from this path were equally valuable as the five stars from other paths, but the game got its first limited five-star Harmony character during the Version 1.6 update.




Honkai: Star Rail – Ascension And Trace Materials For Ruan Mei

Ruan Mei has been one of the most anticipated characters ever since the start of Honkai: Star Rail, and here’s what you need to upgrade her.

The said character being Ruan Mei, one of the geniuses of the Herta Space Station who has Ice as a combat type. Ruan Mei’s kit is quite unique since it allows you to break the enemy’s weakness much faster.

Best Ruan Mei Relics And Planar Ornaments

As Honkai: Star Rail gets more updates, the number of Relics you can choose from for a certain character also increases. However, only a few of these Relics can suit Ruan Mei’s kit, and here’s everything you need to know about them:



Reason For Synergy With Ruan Mei


Messenger Traversing Hackerspace

This Relic set is ideally the best in slot for Ruan Mei, but you’ll have to do quite a lot of work if you want to use it. Ruan Mei needs at least 180 percent Break Effect on her kit to fully use her Talent.

If you can get this Break Effect through the main and sub-stats, you can use this Relic set to give her and her team some extra SPD.

Thief of Shooting Meteor

If you’re struggling to get the right amount of Break Effect on Ruan Mei, you can use this set to get an extra 32 percent while also gaining the ability to regenerate some Energy on Weakness Break.

This is also a beginner-friendly Relic since you start getting it quite early.

Planar Ornaments

Penacony, Land of the Dreams

One of the best teammates you can use with Ruan Mei is Jingliu, and that’s where you can also use this Ornament set. It gives her some Energy Regeneration Rate while also increasing Jingliu’s DMG.

Broken Keel

On the other hand, if you’re planning to use her with non-Ice units, Broken Keel becomes her best in slot because of the extra Crit DMG it gives to all your allies, including the main DPS.

It’s not difficult to build Relics for Ruan Mei, so getting some Effect RES for her is easy as well.

Fleet of the Ageless

Finally, Fleet of the Ageless is a great beginner Ornament set since you can get it in the early worlds. It gives Ruan Mei some survivability while also increasing your entire team’s ATK.

Ruan Mei Relic Stat Priority

When you get a new character in Honkai: Star Rail, the hardest part about building them is getting the correct main and sub-stats on the perfect sets. Thankfully, this isn’t too hard for Ruan Mei since she only needs a couple of stats to be good:


Main Stat Priority

Sub Stat Priority



Break Effect > HP Percent > ATK Percent > SPD



Break Effect > HP Percent > ATK Percent > SPD


ATK Percent

Break Effect > HP Percent > SPD



Break Effect > HP Percent > ATK Percent

Planar Sphere

ATK Percent

Break Effect > HP Percent > SPD

Link Rope

Break Effect / Energy Regeneration Rate

Break Effect > HP Percent > ATK Percent > SPD

The Link Rope’s main stat depends on your Light Cones and overall Relics.

If you have 150 percent or more Break Effect without the Link Rope main stat, you can go for Energy Regeneration Rate.

Best Ruan Mei Light Cones

Honkai: Star Rail is a little restrictive when it comes to Light Cones since you can only use the Light Cones that belong to the character’s path. However, Ruan Mei still has quite a few choices:

Past Self in Mirror

This is her signature Cone, and of course, the best in slot for her. It gives her a whopping 60 percent Break Effect, making it much easier to build your Relics. Moreover, your allies gain extra DMG when she uses her Ultimate.

Finally, this can also help your entire team get their Ultimate faster since it increases their Energy by ten at the start of every turn.

Memories of the Past

This is essentially the four-star version of her signature Light Cone, giving you a 56 percent Break Effect at the maximum Superimpose. While this might be close to the five-star version, the rest of the stats that it gives aren’t available here.

However, you can regenerate a bit of extra Energy every time you attack an enemy.

Planetary Rendezvous

Once again, if you’re planning to use Ruan Mei with Jingliu or any other Ice DPS character, this can be a phenomenal Light Cone as it gives them a 24 percent increased DMG at Superimposition Five.

Carve the Moon, Weave the Clouds

If you can get the premium tier of the battle pass, this Light Cone is an all-rounder for Harmony characters since it constantly provides a random buff to your entire team.

Meshing Cogs

Finally, if you don’t have any of the above Light Cones, this is a great choice for Ruan Mei since it gives her a ton of extra Energy during battle.

Ruan Mei Trace Priority

Ruan Mei has an intricate set of Traces including five active ones that belong to her Basic Attack, Skill, Ultimate, Talent, and Technique, and three more Bonus Abilities. While you can read exactly what they do in the game, here are the main highlights:

  • Her Skill increases your entire party’s DMG and Weakness Break Efficiency for the next three turns.
  • The Ultimate gives her party some all-type RES penetration while also making the enemy actions delayed for much longer after a weakness break.
  • Finally, her Talent can increase your party’s SPD further and let her deal extra Ice DMG whenever an enemy’s Weakness is broken.

With this in mind, you’d always want to upgrade her Skill first since the DMG bonus from it is quite important. This can be followed by her Ultimate and finally her Talent. You can upgrade her Basic Attack up to level four, but you don’t need to go further since she doesn’t deal a lot of damage anyway.

While using Ruan Mei, don’t shy away from breaking the enemy’s weakness with her since that will freeze them, which essentially means that they can’t get a turn for the next three chances.

Is Ruan Mei Worth Pulling?

Out of all the Standard characters in Honkai: Star Rail, Bronya is the only one that consistently stays in the meta, and she belongs to the Harmony path. The same can be said about Ruan Mei since she not only brings in a unique aspect of faster Weakness Break, but also gives a ton of buffs to your entire team.

There’s no doubt that this character will stay in the meta for a long time since it’ll be hard to power-creep her. However, that shouldn’t be the main reason for you to pull a character. If you think that her kit is fun and you’ll enjoy playing her, she’s definitely worth going for.
