Sustain

March 7th is an Ice-element character who follows the Path of Preservation. She excels at applying shields to a single ally and launching counterattacks whenever shielded allies are attacked. Her Ultimate deals AoE Ice damage with a 50% base chance to inflict Freeze. March 7th is a good character for early-game content but struggles in harder endgame challenges. Because her shielding only targets a single ally, she becomes less appealing for tougher difficulties in Divergent Universe and Simulated Universe, where consistent team-wide protection is often needed.

Best Cavern Relics

4pc

Knight of Purity Palace

(2)

Increases DEF by 15%.

(4)

Increases the max DMG that can be absorbed by the Shield created by the wearer by 20%.

This set is particularly good because her shield strength scales with her DEF.

Best Planar Ornaments

2pc

Belobog of the Architects

(2)

Increases 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 is currently her best Planar Ornament set, as it further increases her shield strength. Since March also needs Effect Hit Rate, reaching 50% not only helps her land Freeze more consistently but also grants additional DEF, improving her shield absorption even more.

Substats

DEF% / Effect RES / SPD / DEF

For March 7th, prioritize DEF% as her most important stat since it directly boosts her shield strength and counterattack damage. In the Body slot, go for DEF%, while the Feet can be either DEF% for tankiness or Speed to take more turns. The Planar Sphere is flexible between Ice DMG% for stronger Ultimate damage or DEF% for pure shielding, and the Link Rope works best with Energy Regen Rate to cycle her Ultimate faster or more DEF%. In substats, focus on DEF%, Effect Hit Rate (ideally around 40–50% to reliably Freeze enemies), Speed, and Flat DEF.

Best Light Cones

Inherently Unjust Destiny 5★

SourceLight Cone Event Warp

All-In

Increases the wearer's DEF by 40~64%. When the wearer provides a Shield to an ally, the wearer's CRIT DMG increases by 40~64%, lasting for 2 turn(s). When the wearer's follow-up attack hits an enemy target, there is a 100~160% base chance to increase the DMG taken by the attacked enemy target by 10.0~16.0%, lasting for 2 turn(s).

This lightcone gives her buffing capability whenever she provides her shield into an ally.

Moment of Victory5★

SourceStellar Warp, Light Cone Event Warp, Starlight Exchange, Stellar Convergence

Verdict

Increases the wearer's DEF by 24~40% and Effect Hit Rate by 24~40%. Increases the chance for the wearer to be attacked by enemies. When the wearer is attacked, increase their DEF by an extra 24~40% until the end of the wearer's turn.

This Light Cone is good for providing DEF and Effect Hit Rate for March, increasing her chance to apply Freeze with her Ultimate. However, it also raises her aggro, which can make it harder to decide whether to shield herself or her allies.

Landau's Choice4★

SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp

Time Fleets Away

The wearer is more likely to be attacked, and DMG taken is reduced by 16~24%.

This Light Cone is good for drawing enemy attention to her while also reducing the damage she receives.

This Is Me!4★

SourceBattle Pass

New Chapter

Increases the wearer's DEF by 16~32%. Increases the DMG of the wearer when they use their Ultimate by 60~120% of the wearer's DEF. This effect only applies 1 time per enemy target during each use of the wearer's Ultimate.

This Is Me! greatly increases March’s shield strength and DEF, making her shields much stronger. It also boosts her Ultimate damage based on her DEF, turning her into both a sturdier protector and a better damage dealer when she uses her Ultimate. It’s one of her best Light Cones, especially if you want stronger shielding and higher burst damage.

Day One of My New Life4★

SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp

At This Very Moment

Increases the wearer's DEF by 16~24%. After entering battle, increases All-Type RES of all allies by 8~12%. Abilities of the same type cannot stack.

Day One of My New Life increases March’s DEF, improving her shield strength. It also grants all allies a damage resistance buff when she enters battle, making the whole team a bit tankier.
