Should you pull Asta?

Asta is a free early-game Harmony support who buffs the whole team's ATK and SPD. Great for newer players or budget accounts; veterans with Sparkle/Robin/Tingyun can skip investing heavily.

Pros
  • Free and easy to reach E6
  • Buffs both team ATK and SPD
  • Extremely flexible, fits any team
  • Can refund a Skill Point on Ultimate
Cons
  • Power-crept by 5-star Harmony units
  • Energy-hungry, needs ERR investment
  • Stacking ATK buff ramps slowly early
How to play

Use her Skill each turn to hit multiple enemies and stack her team-wide ATK buff, and keep her SPD very high so she acts first to spread buffs. Fire her Ultimate as soon as you hit 100 energy for the 2-turn team SPD boost.

Aim for 134 SPD minimum, ideally 160+ to enable looping. Prioritize energy regen (ERR rope plus subs) and ~4000-5000 HP for survivability; crit is irrelevant since she isn't a damage dealer.

Eidolons
How far to invest, which milestones matter

E0 (E6 rẻ vì là nhân vật miễn phí, cộng SPD đáng giá) — E0 already works. Since she's free, farm copies from shops/events to reach E6 (permanent SPD boost) — that's the payoff; the middle eidolons matter little.

E1
Star Sings Sans Verses or Vocals★★★★☆
When using Skill, deals DMG for 1 extra time to a random enemy.
Skill deals one extra hit to a random enemy, adding damage and making it easier to hit new targets for more Charging stacks.
E2
Moon Speaks in Wax and Wane★★★☆☆
After using her Ultimate, Asta's Charging stacks will not be reduced in the next turn.
After using her Ultimate, Charging stacks are not reduced next turn, helping sustain the team-wide ATK buff longer.
E3
Meteor Showers for Wish and Want★★☆☆☆
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 without adding new effects, so the power gain is limited.
E4
Aurora Basks in Beauty and Bliss★★☆☆☆
Asta's Energy Regeneration Rate increases by 15% when she has 2 or more Charging stacks.
Energy Regeneration Rate increases by 15% when she has 2 or more Charging stacks, a minor utility boost.
E5
Nebula Secludes in Runes and Riddles★★☆☆☆
Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Only raises Ultimate and Basic ATK levels without new effects, so the impact is small.
E6
Cosmos Dreams in Calm and Comfort★★★★★
Charging stack(s) lost in each turn is reduced by 1.
Charging stacks lost each turn is reduced by 1, making the team-wide ATK buff much more stable and long-lasting for a major power spike.

Skills & Traces
What to level first — tap each skill for details
Skill Leveling Priority
Talent ★★★★★ Talent grants team-wide ATK% based on Charging stacks, Asta's core value, so it should be leveled first.
Ultimate ★★★★☆ Ultimate buffs team SPD and scales with its level, making it the second priority after Talent.
Skill ★★★☆☆ Skill hits multiple enemies to help build Charging stacks for Talent, but its own damage isn't the focus.
Basic ATK ★★☆☆☆ Basic ATK is single-target and largely irrelevant to Asta's support role, so it's the lowest priority.
Trace priority: A4 > A6 > A2 Eidolon priority: E1 = E6 > E2 > E4 > 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.
