Sub-stat priority: ATK% > SPD ≥ Break Effect > (Energy Regen)
▾
Deals Imaginary DMG equal to 140% of Rappa's ATK to one designated enemy.
▾
Deals Imaginary DMG equal to 150% of Rappa's ATK to all enemies.
▾
Enters the "Sealform" state, immediately gains 1 extra turn, obtains 3 points of "Chroma Ink," and increases Weakness Break Efficiency by 50% and Break Effect by 40%. While in the "Sealform" state, Basic ATK is enhanced, and Skill and Ultimate cannot be used. After using Enhanced Basic ATK, consumes 1 point of "Chroma Ink." When "Chroma Ink" is depleted, exits the "Sealform" state.
▾
Each time the enemy target is Weakness Broken, Rappa gains 1 point of Charge, up to a max of 10 points of Charge. When Rappa next launches the third hit of "Ningu: Demonbane Petalblade," additionally deals Break DMG equal to 75% of Rappa's Imaginary Break DMG to all enemies. This DMG can ignore Weakness Type to reduce 2 Toughness, consuming all Charge. Each point of Charge increases the Break DMG multiplier by 63% and increases the Toughness Reduction that can ignore Weakness Type by 1. When Breaking Weakness, triggers the Imaginary Weakness Break effect.
▾
Attacks an enemy, and after entering combat, reduces their Toughness of the corresponding Type.
▾
After using Technique, enters the "Graffiti" state for 20 seconds. While in the "Graffiti" state, moves forward rapidly for a set distance and attacks any enemies touched. 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. At the same time, this unit regenerates 10 Energy.
▾
Deals minor Imaginary DMG to one designated enemy and minor Imaginary DMG to adjacent targets. Attacking enemies without Imaginary Weakness can also reduce their Toughness.
When the Weakness of an elite-level or higher enemy is broken, Rappa additionally gains 1 point(s) of Charge and regenerates 10 Energy.
While in the "Sealform" state, after Rappa uses Enhanced Basic ATK to deal DMG to a Weakness Broken enemy target, converts the Toughness Reduction from this instance of DMG to 1 instance of 60% Super Break DMG.
When an enemy target becomes Weakness Broken, increases the Break DMG taken by 2%. If Rappa's current ATK is higher than 2400, for every 100 excess ATK, additionally increases this value by 1%, up to a max additional increase of 8%. This effect lasts for 2 turn(s).

3★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.
