As March 7th is a Preservation character who fits the tank role, her best light cone is Day One of My New Life. 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 7th, 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 is a four-star bow-wielder who attacks with the power of ice. She 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 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?

March 7th’s best light cone is ‘Day One of My New Life’, which is brilliant for tank builds due to its defense boost and team-wide damage rest buff. Alternatively, Trend of the Universal Market is a strong option, followed closely by This Is Me!

Finally, if you’re looking for a more accessible option, the three-star light cone Amber at S5 is a good choice.

What are the best relics for March 7th?

You can equip March 7th with a total of six relics – four from the normal sets, and two from the Simulated Universe sets. In terms of four-piece sets, Guard of Wuthering Snow is a great choice for boosting her defensive and survivability skills. Alternatively, Knight of Purity Palace is useful if you want to boost her shields.

When it comes to the Simulated Universe sets, it really depends on how far into the game mode you’ve got, and what kind of build you want for March 7th. Fleet of the Ageless is a great option for earlier in the game that boosts her HP and provides a team-wide buff. If you’re leaning into her defensive capabilities, we recommend grinding for Belobog of the Architects to make the most of her shields.
