Should you pull March 7th?

Preservation March 7th is the free shield everyone owns, ideal for new accounts short on a sustainer. Endgame she's outdated though, so if you have Aventurine, Gepard or Fu Xuan, feel free to bench her.

Pros
  • Free, available from the very start
  • Thick shields scaling on common DEF gear
  • Shield taunts enemies, great with Clara
Cons
  • No healing, pure shielding — risky once it pops
  • Falls off hard in endgame vs 5-star shielders
  • Freeze relies on Effect Hit Rate, inconsistent
How to play

Open by using Skill to shield your main DPS (best with counter DPS like Clara). After that just Basic Attack to build energy and re-apply the shield when it breaks. Ultimate deals AoE Ice damage with a chance to Freeze for control.

Eidolons
How far to invest, which milestones matter

E0 (E4/E6 tăng phản đòn nhưng không đáng để cày) — E0 is perfectly fine. E4 and E6 add extra counters and damage, but she's a giveaway unit and isn't worth grinding traces or pulling copies for.

E1
Memory of You★★★☆☆
Every time March 7th's Ultimate Freezes a target, she regenerates 6 Energy.
Regenerating 6 Energy per Ultimate Freeze speeds up Ultimate uptime but depends on the Freeze proc landing.
E2
Memory of It★★☆☆☆
Upon entering battle, grants a Shield equal to 24% of March 7th's DEF plus 320 to the ally with the lowest HP percentage, lasting for 3 turn(s).
An entry-battle shield for the lowest-HP ally is a minor utility with modest shield value and duration.
E3
Memory of Everything★★☆☆☆
Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Purely levels up Ultimate and Basic ATK with no new effect, so the power gain is minimal.
E4
Never Forfeit Again★★★★☆
The Talent's Counter effect can be triggered 1 more time in each turn. The DMG dealt by Counter increases by an amount that is equal to 30% of March 7th's DEF.
Adds one more Counter trigger per turn and boosts Counter DMG by 30% of DEF, making the Talent's counterattack noticeably stronger and more frequent.
E5
Never Forget Again★★☆☆☆
Skill Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Only raises Skill and Talent levels with no new effect, so the impact is low.
E6
Just Like This, Always...★★★☆☆
Allies under the protection of the Shield granted by the Skill restore HP equal to 4% of their Max HP plus 106 at the beginning of each turn.
Shielded allies regenerate HP each turn, giving the team a moderate boost to sustain.

Skills & Traces
What to level first — tap each skill for details
Skill Leveling Priority
Skill ★★★★★ The Skill's shield is March 7th's core job as a sustain unit, so it should be leveled first to absorb more DMG.
Talent ★★★★☆ The Talent's counter is tied directly to the shield mechanic, triggers often, and defines her combat identity, so it ranks second.
Ultimate ★★★☆☆ The Ultimate deals AoE DMG and can Freeze enemies, useful utility but not her main job, so it ranks below Skill and Talent.
Basic ATK ★☆☆☆☆ Basic ATK is mainly a fallback for energy generation and unrelated to her shielding role, making it the lowest priority.
Trace priority: A6 > A4 > A2 Eidolon priority: E4 > E6 > E2 > E1 > E3 = E5

How to read this build page

Every character build page has these parts: recommended Light Cone/Relic sets and stat table, a Trace/skill leveling order, Eidolon milestones worth considering, and a reference SPD threshold. Read them in that order — gear tells you "what to use", Traces tell you "what to level first", Eidolon tells you "is it worth pulling dupes", SPD tells you "how fast you need to be to keep the rotation on time". The section below explains how to read each part and applies the same way to every character on the site — check the exact numbers in the table above this section, since community sources sometimes differ by a few points.

Why the Light Cone and Relic picks make sense

Most characters have a "signature" Light Cone built for their exact role, plus a few cheaper substitutes from the standard banner or easy-to-get 3-4★ cones. Missing the signature isn't a dead end — most characters keep most of their power with a well-matched substitute, typically losing somewhere between a few percent and roughly a fifth of total damage depending on the setup, per most public comparisons.

  • Relic sets (2pc+2pc or 4pc) are picked for the set effect that fits that character's role (single-target DPS, AoE, shield/healing support, Break damage, and so on).
  • Main stats per slot (Body/Feet/Sphere/Rope) and substats follow a priority that changes by role: DPS roles usually chase CRIT Rate/CRIT DMG before ATK%; Break-focused roles prioritize Break Effect; support/healing roles often value Effect Hit/RES or Outgoing Healing over pure CRIT.

These weights differ per character and can shift slightly between ranking sources — follow the exact priority table above rather than applying one formula to every role.

Trace/skill leveling order by role (a general guideline, not a fixed rule)

There's no single order that's correct for every character, and community sources sometimes disagree depending on the team the character is used in — but the general pattern by role is:

  • DPS: level whichever skill (Skill or Ultimate) carries most of the damage for that character first, with Basic ATK usually last if it isn't the main damage source.
  • Support/Buffer: prioritize Traces that boost buff strength or the skill that applies the effect over Basic ATK, since this role's value comes from lifting the team rather than personal damage.
  • Healer/Shielder: prioritize the main healing or shield skill first, since that is the reason the team runs this character.
  • Break/CC: prioritize whichever skill contributes the most Toughness Damage, since the Break/Weakness Break window is where the team dumps damage.

Major Traces unlock at fixed ascension levels in-game, not by choice — but which one to level first (when resources are limited) should follow the role priority above. Since the exact order can differ between ranking sources, check the specific recommendation in the table above for this character.

Eidolons: how far E0 gets you, and which milestone is worth considering

General rule: most characters at E0 (no duplicates) already handle most content, even 5-star characters. Eidolons are a duplicate-fueled upgrade system — higher levels cost more resources for a smaller power gain, and the actual gain varies a lot per character (some barely change role at E0, others shift how they're played at a specific level). The milestones most often cited by the community tend to sit at E1, E2, or E6 depending on the character — but none of these are required to clear the game's content. Check the Eidolon section in the table above for this character's specific milestone and gain; if sources disagree on how to rate a milestone, trust the in-game effect description over a pre-set percentage number.

How to think about SPD breakpoints

SPD (Speed) controls how often a character acts in the turn order — higher SPD means denser actions, and for some roles (especially support/healing that need to buff or heal before the team gets hit) hitting the right SPD "breakpoint" matters more than the raw SPD number. Values like 101 or 134 SPD are often cited as community-common breakpoints (letting a character act again before or after a specific point in certain team setups) — this is crowd-verified action-gauge math, not an official fixed number the game states for every situation. The right breakpoint also depends on the team and allies' SPD, so treat the SPD suggestion in the table above as a starting point to adjust from, not a mandatory target.
