Inherently Unjust Destiny is March 7th's best-in-slot Light Cone, offering everything she wants from a defensive option while also improving her ability to contribute personal damage through her Follow-Up Attacks.

Journey, Forever Peaceful
S5

Increases the wearer's provided Shield Effect by 12.0 / 15.0 / 18.0 / 21.0 / 24.0%. While an ally target has a Shield, their DMG dealt increases by 12.0 / 14.0 / 16.0 / 18.0 / 20.0%.

Sources: Nameless Glory

A strong option for March 7th that improves the strength of her shields while also increasing the damage of allies protected by them, making it especially valuable for a supportive playstyle.

Moment of Victory

When the wearer is attacked, increase their DEF by an extra 24.0 / 28.0 / 32.0 / 36.0 / 40.0% until the end of the wearer's turn.

Sources: Stellar Warp

A strong defensive option that significantly improves March 7th's shielding through its DEF increase. However, it is less suitable when another ally relies on drawing enemy attacks toward themselves.

Day One of My New Life
S5

Increases the wearer's DEF by 16.0 / 18.0 / 20.0 / 22.0 / 24.0%. After entering battle, increases All-Type RES of all allies by 8.0 / 9.0 / 10.0 / 11.0 / 12.0%. Abilities of the same type cannot stack.

Sources: Stellar Warp

March 7th's signature 4-star Light Cone provides strong defensive support while also improving the team's overall survivability, making it a reliable choice for a dedicated support build.

Landau's Choice
S5

The wearer is more likely to be attacked, and DMG taken is reduced by 16.0 / 18.0 / 20.0 / 22.0 / 24.0%.

Sources: Stellar Warp

Increases March 7th's likelihood of being attacked while reducing the damage she takes. Another strong option when no other allies require the enemy to attack them.

Texture of Memories
S5

Increases the wearer's Effect RES by 8.0 / 10.0 / 12.0 / 14.0 / 16.0%. If the wearer is attacked and has no Shield, they gain a Shield equal to 16.0 / 20.0 / 24.0 / 28.0 / 32.0% of their Max HP for 2 turn(s). This effect can only be triggered once every 3 turn(s). If the wearer has a Shield when attacked, the DMG they receive decreases by 12.0 / 15.0 / 18.0 / 21.0 / 24.0%.

Sources: Herta's Store

A solid option for improving March 7th's personal survivability, giving her additional protection and Effect RES when stronger defensive Light Cones are unavailable.

March 7th (Preservation) Build Comments

Character Overview Kit Overview

Character Overview

March 7th provides strong single target-shields while contributing follow-up attacks. Thanks to her ability to Freeze groups of enemies, cleanse allies, and manipulate enemy targeting, March remains a decent option capable of preventing incoming damage through crowd control as much as through direct sustain.

Kit Overview

March 7th's kit revolves around shielding allies, triggering follow-up attacks, and controlling enemy turns. Her Skill grants a decent shield that also increases the ally's aggro, making it ideal for durable allies or for redirecting attacks away from more fragile teammates. Whenever a shielded ally is hit, her Talent launches a counterattack, generating additional damage and helping recharge her Ultimate.

March 7th's Ultimate deals Ice damage to all enemies with a chance to Freeze them, stopping enemy actions and creating valuable opportunities for the team. While its base Freeze chance starts relatively low, her third trace upgrade significantly improves its consistency, allowing March to function as a capable crowd control support. Her first trace also adds extra support by cleansing debuffs when she uses her skill.

March is relatively Skill Point-hungry compared to more recent sustain characters and offers limited offensive contribution outside of her Freeze. As a result, she performs best in teams that can support her Skill Point demands or in encounters where crowd control provides more value than damage or healing.

March 7th (Preservation)'s Best Teams

March 7th Teams

March 7th (Preservation)'s Best Eidolons

E6 – March 7th's most important Eidolon. Allies who have gained a shield through her Skill receive healing at the beginning of each turn. This allows March to provide healing outside of her turn to allies.
E4 – E4 is great as it lets March 7th counterattack one extra time each turn, and each counter deals more damage based on 30% of her DEF, increasing both her damage output and the value of building her DEF.
E2 – It automatically shields the most vulnerable ally at the start of battle, improving team survivability with a DEF scaling shield that lasts 3 turns.
E1 – Freezing enemies restores Energy, letting March 7th use her Ultimate more often for better crowd control and team support.
