What’s the best Honkai Star Rail March 7th build?
March 7th is a four-star Preservation character who deals ice damage. Her kit focuses on supporting and enabling her allies, providing them with shields and freezing their foes. She’s currently the only four-star Preservation character, and is a valuable and affordable asset for any player who prefers a more defensive playstyle.
Here’s a brief overview of our best HSR March 7th build:

Path | Preservation |

Best relic set | Knight of Purity Palace |
Best planar ornament set |
|
Main stats | Body: effect hit rate Feet: speed Planar Sphere: defense % Link rope: defense % or energy regen |
Sub-stats | Defense % > speed > effect hit rate > HP% |
March 7th’s best all-rounder light cone is Day One of My New Life, as it’s the most versatile and is useful in almost all scenarios. Her best relic set is Knight of Purity Palace, and her best planar ornament sets are Belobog of the Artifacts or Fleet of the Ageless.
When building March, we recommend focusing on defense, with some speed and effect hit rate mixed in. You can also go for an energy regen link rope if you feel she’s not getting her ultimate up fast enough.
In terms of skill priorities, we recommend focusing on her skill, then her ultimate, followed by her talent and her basic attack. In terms of traces, you should go for purify first to cleanse those annoying debuffs, then level up ice spell and reinforce.
How to use March 7th
March 7th treads the path of the Preservation, and her multi-target attacks and ability to shield an ally make her a great fit for a support/sub-DPS hybrid role. She also offers great utility through her ability to freeze her enemies, allowing you to strike them down while keeping yourself safe.
When in battle, we recommend that you use her skill to shield your DPS wherever possible or to deflect some of the damage if an enemy targets a specific ally.
Aside from that, feel free to use her basic attack and ultimate as frequently as possible, especially when you’re facing an enemy that’s weak to ice, in order to increase your chances of freezing your opponents.
When exploring, her ranged technique makes her particularly good at engaging battles without being detected, it also has a chance to freeze enemies weak to ice, allowing you to start the fight with the upper hand. The wide AoE of her ultimate is also very handy for freezing an entire enemy team to give you a moment’s respite.
Unfortunately, her personal damage isn’t the best, and her shield is easily outshone by powerful Preservation characters like Gepard – but we all know what it’s like trying to get a specific standard five-star character. She is still a pretty valuable utility character to support your main DPS, especially earlier on in your journey, due to both her handy follow-up attacks and the fact that you get her for free as soon as you start. Plus, as you further level up her traces, she can also cleanse any allies she shields of debuffs.

What are the best light cones for March 7th?
Day One of My New Life is the best all-rounder light cone for March 7th. It offers a welcome defense increase while also boosting the damage reduction of all teammates. This makes it the most flexible option for March as it’s useful in all scenarios, so you don’t have to worry about changing it if you switch up team comps.
Moment of Victory is a great light cone for March 7th in a tank role. It provides a huge amount of defense and a respectable amount of effect hit rate, though it does taunt enemies to hit March. This can still be useful if you’re using March as a tank, but you should avoid it if you plan on pairing her up with other characters that rely on being hit, such as Clara.
She Already Shut Her Eyes is the best light cone for March 7th if you want to focus on keeping your team alive. It offers a near full heal at the start of every round, making it a great choice if you’re using March as a solo sustain (in other words, if you aren’t using a healer alongside her).
Landau’s Choice at S5 is March 7th’s best four-star light cone, offering decent damage reduction. However, it also increases the chances that enemies will hit March. Therefore, like Moment of Victory, it’s not the best if you’re pairing her up with other characters that need to be hit.
