Should you pull Phainon?

Phainon is a premier 3.x Physical (Destruction) hypercarry who transforms and solo-carries the field. Roll if you want a plug-and-play DPS for every mode; skip if you're stacked on DPS and short on supports.

Pros
  • Top-tier at both single-target and AoE
  • Extremely tanky, near-unkillable while transformed
  • Self-applies Physical weakness to all enemies
  • Excellent across MoC, Pure Fiction, and Apocalyptic Shadow
Cons
  • Needs turn-advance supports (Sunday/Cerydra) to fully shine
  • Transformation rotation is fiddly at first
  • Transformed Speed is fixed, so Speed boots add little
How to play

Spend the first turns using Skill to build resolve/stacks and enter his enhanced (Khaos) transformed state.

Once transformed, spam his enhanced attacks that bounce across all enemies, then Ultimate to unlock the damage buff. Let supports like Sunday and Cerydra target Phainon directly to advance his turns and feed energy.

Best teams for Phainon

Core: Phainon + Cerydra + Sunday + Aventurine - both supports target Phainon to advance turns and generate extra Coreflame.

Variant: swap Cerydra for Robin to fast-forward rotations.

Budget: Bronya + Tingyun + Gallagher still performs well.

Eidolons
How far to invest, which milestones matter

E0 (E1 tiện, E2 rất mạnh - gần như đổi hẳn nhân vật) — E0 is already top-tier and complete. E1 speeds up his Ultimate, but his signature cone grants a similar base-Speed boost, so grab the cone first. E2 is a major spike (extra turn, Physical RES shred) and is the best duplication milestone.

E1
Fire and Light Bind Virtue and Vice★★★★★
The base SPD inheritance ratio for Khaslana's extra turn increases to 66%. For every enemy target defeated in one battle, additionally increases this ratio by 1.5%, up to a max of 84%. When using Ultimate, increases CRIT DMG by 50%, lasting for 3 turn(s).
Greatly boosts Khaslana's SPD inheritance ratio for extra turns (up to 84%) and grants CRIT on Ultimate, meaningfully increasing action frequency and damage.
E2
Sky and Earth Churn Mortal Froth★★★★★
Khaslana's Physical RES PEN increases by 20%. When one use of "Foundation: Stardeath Verdict" consumes 4 "Scourge" point(s), gains 1 extra turn.
Adds a flat 20% Physical RES PEN (a major damage boost) and can grant an extra turn when the ultimate consumes 4 Scourge points.
E3
Depths of Quiet, Entombed in Ruin★★☆☆☆
Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Purely raises Ultimate and Basic ATK skill levels with no new effect, so the power gain is small.
E4
Faces of Titans, Blurred by Time★★★☆☆
When using "Calamity: Soulscorch Edict," additionally gains 4 stack(s) of "Soulscorch."
Grants 4 extra Soulscorch stacks when using Calamity: Soulscorch Edict, boosting that state's effects but only in a specific situation.
E5
The Wheel Spins Forevermore★★☆☆☆
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 with no new effect, contributing relatively little power.
E6
Embers of Old Rise Still★★★★★
The number of overflow points allowed for "Coreflame" no longer has an upper limit. When the battle starts, gains 6 point(s) of "Coreflame." After using the attack from "Foundation: Stardeath Verdict," additionally deals True DMG equal to 36% of the total DMG dealt in this attack to the enemy target with the highest HP.
Removes the overflow cap on Coreflame, starts battle with 6 Coreflame points, and deals bonus damage after Foundation: Stardeath Verdict, substantially transforming the character's power and playstyle.

Skills & Traces
What to level first — tap each skill for details
Skill Leveling Priority
Skill ★★★★★ The Skill line holds Khaslana's biggest hit in the whole kit (Foundation: Stardeath Verdict, up to 1463% ATK) plus Calamity: Soulscorch Edict which forces enemy action, making it the main damage source.
Talent ★★★★☆ The Talents govern the "Coreflame"/"Scourge" resources that gate and sustain the Khaslana transformation, and are paired with Skill at E5, showing they scale alongside the main damage output.
Ultimate ★★★☆☆ The Ultimate merely triggers the transformation and applies Physical Weakness to enemies without dealing direct damage itself, and it's grouped with Basic ATK at E3 (the weaker eidolon pair), so it's a lower leveling priority.
Basic ATK ★★☆☆☆ Even though Khaslana's enhanced Basic ATK still deals a decent AoE hit, per standard HSR convention Basic ATK remains the last ability to level up.
Trace priority: A6 > A2 > A4 Eidolon priority: E1 = E2 > E6 > 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.

Where to dig deeper

This section only teaches you how to read the page — for deeper comparisons, use the dedicated tools:

  • Teams for full in-game comps with rotation order.
