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.
Sub-stat priority: CRIT Rate / CRIT DMG > ATK% > SPD
▾
Deals Physical DMG equal to 140% of Phainon's ATK to one designated enemy.
▾
Gains 2 point(s) of "Coreflame," dealing Physical DMG equal to 375% of Phainon's ATK to one designated enemy and Physical DMG equal to 150% of Phainon's ATK to adjacent targets.
▾
Transforms into Khaslana. During the transformation, deploys the Territory "Ruinous Irontomb." Within the Territory, other teammates depart and cannot take action, and all enemies have Physical Weaknesses. Khaslana does not enter his own turn, but has 8 Khaslana's extra turn(s), with a SPD set at 60% of Khaslana's base SPD. When the last of Khaslana's extra turns starts, immediately launches a final hit and deals Physical Ultimate DMG equal to 1200% of Khaslana's ATK that is distributed evenly across all enemies.
▾
Phainon's Talent. When "Coreflame" reaches 12 point(s), can activate Ultimate. Even after reaching the limit, can still hold up to 3 overflow point(s). When the transformation ends, gains "Coreflame" based on the number of overflow points. When Phainon is targeted by an ability from any other target, gains 1 "Coreflame" point. And if the ability is cast by one of Phainon's teammates, can also increase Phainon's CRIT DMG by 38% for 3 turn(s).
▾
Khaslana's Talent. Upon transformation, gains 4 point(s) of "Scourge". If this happens during an ally target's turn, then the duration of all buffs on that target is extended by 1 turn and the current turn ends. Khaslana is immune to Crowd Control debuffs, has 1 Enhanced Basic ATK and 2 Enhanced Skills, but cannot use Ultimate. During the transformation, increases ATK by 100% and Max HP by 338%. After using an attack, restores HP equal to 20% of his Max HP. When Khaslana takes a killing blow, he will not get knocked down. Instead, he will restore HP equal to 25% of Max HP and immediately launch a final hit. For every 1 remaining Khaslana's extra turn, the final hit's DMG multiplier decreases by 12.5% of its original multiplier value. When the transformation ends, increases all allies' SPD by 15% for 1 turn.
▾
Attacks an enemy, and after entering combat, reduces their Toughness of the corresponding Type.
▾
While Phainon is in the team, increases Max Technique Points by 3. When actively using this Technique, consumes 2 Technique Points and immediately attacks all enemies within a certain range. After entering combat, regenerates 25 Energy for allies and gains 2 "Scourge" and 1 Skill Point(s). Deals Physical DMG equal to 200% of Phainon's ATK to all enemies at the start of each wave. If attacking a normal enemy, immediately defeats them without entering combat. No Technique Points are consumed if no enemies are hit.
▾
Gains 2 point(s) of "Scourge", dealing Physical DMG equal to 350% of Khaslana's ATK to one designated enemy and Physical DMG equal to 105% of Khaslana's ATK to adjacent targets.
▾
Gains "Scourge" by an amount equal to the number of enemies and 1 stack of "Soulscorch," then causes all enemies to immediately take action. While in the "Soulscorch" state, Khaslana takes 75% reduced DMG. After an enemy target attacks or takes action, gains 1 more stack of "Soulscorch." After said enemy targets finish their actions, immediately launches Counter, deals Physical DMG to all enemies equal to 50% of Khaslana's ATK, and additionally deals 4 instance(s) of DMG, with each instance being Physical DMG equal to 38% of Khaslana's ATK dealt to one random enemy. Afterward, "Soulscorch" is dispelled. Each "Soulscorch" stack increases the DMG multiplier of said Counter by 20% of its original multiplier value. DMG dealt through this ability is considered as Skill DMG. If "Soulscorch" is still active at the start of Khaslana's extra turn, immediately launches Counter.
▾
Dispels all debuffs on this unit, then deals Physical DMG equal to a max of 1463% of Khaslana's ATK. For every 1 point of "Scourge" consumed, deals 4 instance(s) of DMG, with each instance being Physical DMG equal to 56.3% of Khaslana's ATK dealt to one random enemy. When consuming 4 point(s) of "Scourge", additionally deals Physical DMG equal to 563% of Khaslana's ATK, which is evenly distributed across all enemies.
When the battle starts, gains 1 point(s) of "Coreflame." When the transformation ends, gains 3 point(s) of "Coreflame."
When receiving healing or a Shield from a teammate, deals 45% increased DMG for 4 turn(s). This effect cannot trigger repeatedly within one turn. When receiving an Energy Regeneration effect from a teammate's ability, gains 1 point(s) of "Coreflame."
When entering combat or ending transformation, increases ATK by 50%. This effect can stack up to 2 time(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.
