InHonkai: Star Rail, Memory of Chaos can be considered the pinnacle of challenges that await you on your Trailblazing journey. Each level of MoC gets progressively harder, so if you want to climb this mountain you’ll need more than just your favorite DPS and a dream. Achieving success in this game mode boils down to smart strategizing and effective team synergy, so picking the right characters for the job is critical.
Whether you’re a veteran looking to optimize your team or a new player hoping to tackle this boss gauntlet, these characters should be your go-to picks for navigating its toughest stages. From supportive specialists to powerhouse DPS, here’s a rundown of the best characters you should consider for the challenge.
10Gallagher
Gallagher has firmly secured his place as one of the best four-star characters in the game. He is a Fire-element Abundance Path character, offering teamwide healing, debuff cleansing, and excellent SP generation. He also has the secondary utility of being an excellent break damage support, and his Ultimate can pack a big punch against Fire-weak enemies.
His flexibility allows him to easily find a place in most teams, but Gallagher really comes into his own in break-focused team compositions. For characters like Boothill or Firefly, Gallagher’s kit allows them to perform at their peak in MoC. Regardless of your team archetype, Gallagher remains useful for maintaining a steady flow of toughness damage without sacrificing the team’s sustain.
9Kafka
Kafka is amust-have for any Honkai: Star Rail player that loves the DOT playstyle. She is the queen of this archetype, and any MoC rotation that emphasizes DOT will immediately make her a top choice. Her ability to stack DOT’s on enemies and subsequently detonate them with her low energy cost Ultimate gives her a surprising amount of burst potential.
For even greater power, pairing her with any DOT Supports like Black Swan or Guinaifen can noticeably amplify her effectiveness. Kafka is perfect for dealing consistent AOE damage, and as the only character (currently) who can trigger DOT effects immediately, her place in the MoC meta is undeniable.
8Boothill
Boothill’s significant damage potential and self-enabling kit is what makes him an essential pick for Memory of Chaos. His kit revolves around ramping up his damage by breaking enemy toughness bars and then blasting them with his arm cannon for tons of damage. What makes him stand out is his ability to implant Physical weakness onto a single enemy through his Ultimate. This solves any element type mismatching that might otherwise hamper his damage, and also makes him perfect for slaying the bosses of MoC.
For even better results, you may pair Boothill with characters like Bronya or Ruan Mei, who can further amplify his Break-damage potential. The ability to trivialize tough enemies through massive Breaks, whilst dealing significant Physical damage even after enemies are weakness broken, makes him a formidable force in high-level Memory of Chaos content.
7Fu Xuan
Fu Xuan’s role in Memory of Chaos is admittedly simple but incredibly effective. In short, (get it) she is a total damage sponge. As a Preservation Path character with the unique ability to redistribute team damage to herself and mitigate incoming hits, she is one of the best defensive characters in the game. Her Ultimate additionally provides some health recovery for the team, allowing her to remain effective even during drawn-out boss fights.
Fu Xuan is additionally able to boost Crit rates, allowing her to shine when paired with DPS units that focus on Crit damage, such as Acheron or Seele. She is the anvil that will hold the enemies back while the hammer of your DPS takes them down.
6Bronya
Bronya’s 100 percent action advance skill single-handedly solidifies her place as Honkai: Star Rail’s number one Standard Banner character. As a Harmony Path character, she specializes in essentially doubling your DPS turns and amplifying their damage output. Her skill grants total action advance to a designated character, allowing them to immediately take action even after their turn has passed. This ability makes her almost universally useful, as long as you have the Skill points to support the extra action.
For Memory of Chaos, Bronya works especially well with Jingliu, Boothill, and any DPS who wants extra turns and boosted damage, something which applies to most of them. Her strategic importance and availability in the Standard Banner makes her a great general pick when building a team for MoC.
5Ruan Mei
Ruan Mei is aformidable general addition to any team, excelling at boosting team speed (which is highly valuable), providing damage amplification, and delaying enemy actions. While it’s true that she is almost essential in Break-focused teams, her multititude of buffs and Skill point positive playstyle will certainly be appreciated in just about any team that attempts to take on the floors of MoC.
Ruan Mei may not seem very flashy, but the menagerie of team-wide benefits she brings to the table makes her one of the most universally used Supports in the game, even more so than Bronya. You really can’t go wrong when putting Ruan Mei on your roster.
4Acheron
When Acheron arrived in Honkai: Star Rail, the balance of power for all DPS characters shifted forever, and for good reason. She is a Nihility Path character with a focus on building up to her incredible Ultimate, as the damage it can inflict will completely decimate any enemies who dare to appear on your screen.
A stacking debuff mechanic behind her Ultimate keeps this from getting too out of control, but with the proper Nihility-focused team setup, Acheron can take down any MoC floor, regardless of if their Weakness-type is Lightning or not. Pair Acheron with other debuff-heavy characters like Silver Wolf, Pela, or Jiaoqiu if you want to supercharge her damage potential even further.
3Robin
Robin brings a fantastic amount of offensive support buffs that, in a vacuum, can outmatch all the other Supports in the game. As a Harmony Path character, her core gameplay is to enhance the team’s overall damage potential and give them more turns to act. In Memory of Chaos, where every turn counts, Robin’s buffs can make or break a fight. This is especially true when running a Follow-up attack team, which benefits the most from the buffs Robin offers.
In teams featuring high-damage characters like Dr. Ratio or especially Feixiao, Robin’s role is clear: keep your team’s damage flowing at full throttle. Her versatility in buffing makes her a must-have and practically future-proof as a Harmony character in your account.
2Feixiao
If you’re looking for a true powerhouse that can cut down single boss targets like a breeze,Feixiao is yourgirl. As a Wind Hunt character, she delivers exceptional single-target damage, which is especially useful against the bosses and tougher enemies in Memory of Chaos. Her kit allows her to stack multiple hits on a single target through consistent follow-up strikes, ensuring that she can rapidly deliver substantial damage.
Not only is Feixiao’s damage output significant, but she is also easy to play. In a mode like MoC where each decision can make a difference, not having to spend too much time thinking about how to use Feixiao effectively gives you more headroom to focus on piloting the rest of your team.
1Firefly
While Boothill is the king of regular Break-damage, Firefly takes his crown when it comes to Super Break. She offers a fantastic amount of blast damage, and when the enemy’s toughness bar is broken, she can make exceptionally quick work of them.
All this potential comes from her Ultimate, which enhances both of her attacks, grants self-healing, and allows her to implant Fire-weakness, which is critical for any Break character. This makes her almost universally useful in MoC, unless a mechanic comes out that completely negates the toughness bar.
Even better, Firefly has almost immediate access to her Ultimate when a battle starts, meaning she will rarely be left without her enhanced abilities. Her ability to deal with both large groups and tougher targets makes her one of the best units for MoC.
