March 7th (Preservation) | Honkai: Star Rail

Overview

Ice Preservation support with a single-target shield, conditional targeting increase, Counters and an area Freeze attempt.

Role

Focused shielding and conditional control.

Playstyle

Shield the ally who should receive protection and attention, Basic while that shield is adequate, and use Ultimate when Freeze can interrupt an important enemy sequence.

Why It Works

Attacks on shielded allies can trigger March's Counters, while Purify lets Skill remove one debuff.

Watch For

Skill raises the recipient's chance of being attacked only when their HP is at least 30%. A single shield does not protect the whole team from area damage.

Playstyle

Combat Flow

Choose the shield recipient according to the enemy attack pattern and the team's needs. Reapply Skill when protection expires, breaks or a cleanse is needed; otherwise Basic for Skill Points. Time Ultimate for useful control rather than assuming every target will Freeze.

Key Notes

Reinforce extends the Skill shield from three turns to four.
Ice Spell raises Ultimate's Freeze base chance to 65%; enemy resistance and immunity still matter.
Counters can trigger twice per turn at base and once more at E4.
Freeze reduces enemy attacks, which can work against a Counter carry's damage plan.
A cone that increases March's own targeting chance can divert hits from the ally she intended to protect.

Build & Investment

Light Cones

Primary

Day One of My New Life

Adds DEF and team All-Type RES without increasing March's own targeting chance.

Alternative

Inherently Unjust Destiny

Adds DEF; Counters can apply a damage-taken debuff when the application succeeds. Its shield-triggered CRIT DMG buff is personal.

Situational

Moment of Victory

Adds DEF and Effect Hit Rate, but draws attacks toward March. Choose it when she is the intended target rather than another shielded ally.

Situational

Trend of the Universal Market

For a self-targeting Acheron setup: attacks on March can apply Burn. Use Skill on March when directing hits to her is appropriate, and account for resistance.

Relics

Primary

Self-Enshrouded Recluse

Strengthens shields and grants CRIT DMG to each ally while they hold a shield supplied by March.

Alternative

Knight of Purity Palace

Adds DEF and shield absorption for a defensive build.

Planars

Primary

Broken Keel

At 30% Effect RES, grants team CRIT DMG while improving March's resistance.

Situational

Belobog of the Architects

Adds DEF, with another 15% DEF at 50% Effect Hit Rate. Useful when a Freeze-focused build already needs Effect Hit Rate.

For shielding, prioritize actions and DEF. Move Effect Hit Rate ahead of DEF in a deliberate Freeze build, while keeping enough durability to survive.

Eidolon Investment

E0 provides shield, cleanse through Purify, Counters and Freeze attempts. E1 supports control when Freeze lands; E6 adds limited healing but does not solve every team sustain need.

Day One supports protection without competing for targeting; Moment of Victory fits a self-targeting plan rather than every team.

Each target Frozen by Ultimate restores 6 Energy to March. Resisted Freeze provides no such return.

At battle start, shields the ally with the lowest HP percentage for three turns; it does not refresh shields after follow-ups.

Adds one Counter per turn and adds damage equal to 30% of March's DEF to Counter damage.

An ally protected by her Skill shield heals at the start of their turn for 4% of their Max HP plus 106.

Teams

Recommended Teammates

Acheron

Acheron can gain Slashed Dream from successful debuffs. With Trend equipped, self-shielding March can invite enemy hits and Burn attempts, subject to resistance and Acheron's trigger limit.

Clara

March can shield Clara and increase her targeting chance while Clara is at least 30% HP. Avoid unnecessary Freeze when Clara needs enemies to attack, and plan healing or additional protection for the rest of the team.
