Eidolons
How far to invest, which milestones matter

E0 (E1 rất đáng tiền, E6 mạnh) — E0 is fully playable. E1 (15% DEF ignore + energy) is the best value stop. E6 smooths energy generation and is very strong but optional.

E1
Returned Is the Revenant With No Ferry Toll★★★★☆
During the "Sealform" state entered by using Ultimate, DMG dealt by Rappa ignores 15% of the targets' DEF. After exiting the "Sealform" state, regenerates 20 Energy.
Ignoring 15% DEF during Sealform plus 20 Energy on exit meaningfully boosts damage and Ultimate uptime.
E2
Free Is the Mind Enlightened by Haikus★★☆☆☆
The Enhanced Basic ATK's first 2 hits have their Toughness Reduction against the one designated enemy increased by 50%.
A 50% Toughness Reduction boost on the first 2 hits of the Enhanced Basic ATK only speeds up Break slightly and doesn't change the kit.
E3
Many Are the Shrines That Repel No Hell★★☆☆☆
Skill Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Purely raises Skill and Talent levels by 2, a plain numeric bump without a real power spike.
E4
Lost Is the Nindō Devoured by Time★★★☆☆
While in the "Sealform" state, increases all allies' SPD by 12%.
A 12% team-wide SPD buff during Sealform is useful team support but only active while her Ultimate state is up.
E5
Steady Is The Ranger With Unerring Arrows★★☆☆☆
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, a pure stat upgrade with no new effect.
E6
Righteous Is the Wrath That Spares No Evil★★★★★
When battle starts, Rappa gains 5 point(s) of her Talent's Charge, and its upper limit increases by 5 point(s). After launching the third hit of "Ningu: Demonbane Petalblade," gains 5 point(s) of Charge.
Grants 5 Charge and raises the cap at battle start plus more Charge after the third Ningu hit, letting Rappa trigger her powerful Talent Break DMG much faster and more often, a major power spike.

Skills & Traces
What to level first — tap each skill for details
Skill Leveling Priority
Basic ATK ★★★★★ Once Ultimate triggers the 'Sealform' state, only the Enhanced Basic ATK can be used, making it Rappa's repeated main damage/Break source.
Talent ★★★★★ The Talent adds bonus Break DMG on the 3rd hit of the Enhanced Basic ATK once enough Charge is stacked, directly scaling her core damage output.
Skill ★★★☆☆ Skill is an AoE attack used outside Sealform to deal wide DMG and weaken targets, but it is not her primary damage source.
Ultimate ★★☆☆☆ Ultimate mainly unlocks the Sealform state and buffs Break Efficiency/Break Effect rather than dealing its own %ATK damage, so leveling it has little direct damage impact.

During the rapid movement, can block all enemies' attacks. Using an attack in the "Graffiti" state can end the state's duration early. After entering combat via attacking enemies, deals 30 Toughness Reduction regardless of Weakness Type and Break DMG equal to 200% of Rappa's Imaginary Break DMG to each enemy target, and deals Break DMG equal to 180% of Rappa's Imaginary Break DMG to adjacent targets.

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.
