Best March 7th Tank Build – Honkai: Star Rail

Honkai Star Rail's most dangerous Ice Tank.

March 7th can truly save your Honkai: Star Rail team in a pinch, but players need to make sure her defensive stats are up to par before they begin to rely on her.

In Honkai Star Rail, you’ll meet plenty of enemies that have the ability to decimate your health bar.

This is where March 7th comes in. Her pep and positivity pave the way for her protective capabilities that can save your team from the toughest enemies.

Who is March 7th?

March 7th is a free unit in Honkai Star Rail that is able to shield her allies and draw the attention of her enemies with her Skill, The Power of Cuteness.

Her name also happens to be the same day she woke up on the Astral Express with no memories of her life before that moment. She hopes to uncover remnants of her past by traveling alongside the express.

If players are able to get her to Eidolon 6, then she can truly maximize the capabilities of her shield ability which is invaluable in Honkai: Star Rail.

She is featured in the Swirl of Heavenly Spear Banner, so players have an increased chance to pull her and reach higher Eidolons.

ClaraClara (The Destruction) PhysicalMain DPSClara has the “Mark of Counter” ability to counterattack enemies continuously. Her companion, Svarog, can also reduce the damage she takes by 15%. When you pair her up with March 7th, they become the complete defensive and offensive package.
PelaPela (The Nihility)IceSupportPela can lower the defense of all her enemies. This allows Clara and March 7th to take down enemies more quickly.
AstaAsta (The Harmony) FireSupportAsta can increase your team’s speed and attack, allowing them to build up damage before the enemies can fight back. When you pair this up with March 7th, it allows you to reduce the effectiveness of enemies greatly.

It is difficult to obtain all of the characters you want early on in Honkai: Star Rail, but thankfully players can use the Departure Warp to at least secure their first 5-Star.

There are also ways to guarantee yourself a 5-Star of your choice from the Stellar Warp banner.

Most Powerful March 7th Light Cones

If you’re using March 7th alongside Clara, then the best Light Cone to use is the Day One of My New Life because it boosts everyone’s DMG RES.

It’s also a better option than the 5-Star Light Cone, Moment of Victory, because it doesn’t take away the agro from Clara. You want enemies to focus on Clara to make the best use of March 7th as a Tank.

Day One of My New Life

March 7th is a strong character that can tank damage and potentially keep your DPS characters alive through some of the strongest attacks in Honkai: Star Rail. It is important to prioritize her shield ability and defensiveness.

This Light Cone truly establishes the role of March 7th as a Tank. It allows her to increase her defense exponentially while also giving her allies a welcomed boost.

Once you get the Light Cone you want, make sure you properly upgrade it to maximize its potential.

Moment of Victory

Increases chance to be attacked by enemies. When the wearer is attacked, increases DEF by an extra 24%/30%/36%/42%/48% until the end of the wearer's turn.

Moment of Victory allows Mach 7th to shine as a Tank due to its ability to increase the wearer’s DEF and Effect Hit Rate.

This a great Light Cone only when you aren’t using Clara on your team. Since it takes the attention of enemies away from Clara, it could actually hurt your team comp.

But if you don’t have Clara, then this is arguably the best Light Cone for March 7th, stats-wise.

You want March 7th to have the ability to survive on her own while offering support to your other characters. She is also a great source of damage, and her Ice element allows her to freeze enemies.

Overall, when built properly, she is one of the best Tank characters in Honkai: Star Rail, and she is a free unit that players can build early on.

Best March 7th Free-to-Play Team
