Which Relics should I use for March 7th in Honkai Star Rail?
For the best Honkai Star Rail March 7th build make use of two different sets that improve DEF, shields, or Effect Hit Rate to enhance her tanking ability.
| Relic Set | Effect |
| Knight of Purity Palace |
Two-piece: Increase DEF by 12%. Four-piece: Increase the max damage that can be absorbed by the shield created by the wearer by 20%. |
| Belobog of the Architects | Two-piece: Increase the wearer’s DEF by 15%. When the wearer’s Effect Hit Rate is 50% or higher, the wearer gains an extra 15% DEF. |
This makes a four-piece Knight of Purity Palace and two-piece Belobog of the Architects the best option for March 7th. Purity Palace provides a nice 12% DEF boost which, as March 7th’s main scaling stat, will improve the effectiveness of all her abilities. Not only that, but it also offers a huge 20% buff to shield strength, letting March protect her allies even more effectively. Likewise, the Belobog set will increase DEF even further for similar effect.
While a damage setup is not recommended for the best March 7th build in Honkai Star Rail, it is possible. If you would like to have her fill a more balanced role between tank and DPS, then you could use a four-piece set of Hunter of Glacial Forest and two-piece Musketeer of Wild Wheat. This will improve her Ice damage and overall ATK quite significantly, letting her unleash more deadly attacks. Again though, her damage will not be able to compete with that of a DPS character like Honkai Star Rail Jing Yuan or Honkai Star Rail Seele.
Which Light Cone should I use for March 7th in Honkai Star Rail?
March 7th’s best Light Cone is Moment of Victory. However, there are plenty of alternatives if you don’t own this five-star Light Cone.
| Light Cone | Effect |
| Moment of Victory (Best) | Increases the wearer’s DEF by 24% and Effect Hit Rate by 20%. Increases the chance for the wearer to be attacked by enemies. When the wearer is attacked, increases their DEF by an additional 24% until the end of their turn. |
| Day One of My New Life (Alt) | Increases the wearer’s DEF by 16%. After entering battle, increases the DMG RES of all allies by 8%. Effects of the same type cannot stack. |
| This Is Me! (Alt) | Increases the wearer’s DEF by 12%. Increases the damage of the wearer when they use their ultimate by 50% of the wearer’s DEF. This effect can only apply once per enemy target. |
| Amber (F2P) | Increase the wearer’s DEF by 16%. If the wearer’s current HP is less than 50% of their max HP, increase their DEF by a further 16%. |
Moment of Victory, Gepard’s signature Light Cone, will be the perfect choice for the best Honkai Star Rail March 7th build. Firstly, it massively increases her DEF% and Effect Hit Rate%. Paired with the Belobog of the Architects set, this will let you gain an additional 15% DEF on top of the already excellent benefits. Moreover, it will also help March gain the attention of enemies, increasing her chance to be attacked. With such high DEF, she’ll be able to tank the hits very well, giving her allies the opportunity to attack unscathed.
Thankfully, there are great alternatives to this five-star Light Cone. The best alternative option is actually March 7th’s signature Light Cone, Day One of My New Life. This will increase her DEF by a significant amount while also increasing the damage resistance of all allies, providing some valuable extra team utility.
Another four-star alternative is This Is Me!, which once again increases DEF to improve the effectiveness of her abilities. However, it will also increase the damage of her ultimate based on her DEF stat, helping to improve her damage based on her main scaling, rather than ATK.
As for a three-star option, Amber will be your best bet. This will improve March 7th’s DEF by at least 16% and even double this effect if her HP is less than 50% of her max HP. While it’s not as flashy as the four-star or five-star options, Amber will still be able to improve the potency of the best Honkai Star Rail March 7th build.

| Dan Heng (DPS) | Serval (Sub-DPS) | Asta (Support) | March 7th (Tank) |

| Reinforce (Trace Ascension) | The duration of the shield generated by her skill is extended for one turn. |
| Ice Spell (Trace Ascension) | Increase the base chance to Freeze enemies by 15% from March 7th’s ultimate. |
March 7th’s abilities centre around tanking, protecting allies, and inflicting the powerful controlling effect of Freeze. A Frozen enemy will be unable to move and take a small amount of Ice DMG as a result. While it won’t deal much damage without improving her ATK, it will provide invaluable utility since your enemies won’t be able to fight back, giving allies an opportunity to attack. March 7th is also a great shielder, with her skill granting a strong shield to an ally.
Overall, March 7th will help keep the team alive through providing shields and Freezing opponents, rendering them unable to attack. If you’re having trouble staying alive in long or tough fights, try adding her into the mix.

| Just Like This, Always | Allies under the protection of the shield granted by her skill restores HP equal to 6% of their max HP plus 48 at the beginning of each turn. |
Eidolons are the equivalent of Constellations from Genshin Impact, acting as permanent buffs for characters after each additional copy of the character you receive.
March 7th’s Eidolons build upon her strengths in several ways to make her a formiddle tank, despite only being a four-star unit. Her first Eidolon will actually improve her damage output slightly, increase the number of times her talent’s Counter effect can be triggered each turn and causes it to scale based on DEF rather than ATK. While it won’t make her a DPS character, it can’t hurt to have bonus damage. The remainder of her Eidolons focus on self-sustain and tanking. For example, her second Eidolon will regenerate Energy for every enemy Frozen by her ultimate, letting March keep the ball rolling. Her sixth Eidolon is perhaps the most interesting, offering a slight heal to allies until the protection of her skill’s shield.
