Release3.4
Phainon is a Physical Destruction damage dealer who doesn't use Energy: he collects "Coreflame" whenever an ability targets him, and at 12 Coreflame transforms into Khaslana. During the transformation his teammates leave the field, every enemy gains a Physical Weakness, and he gets 8 extra turns with massively boosted ATK and HP to unleash devastating Skills. He shines in single-target fights with action-advance supports and Cerydra.
Main DPS
Light Cones
Thus Burns the Dawn BiS
5★
Signature and clear best choice: the highest base ATK in the game (687), 18% DEF ignore, +12 base SPD (which does speed up Khaslana) and a big DMG boost after his Ultimate.
Base SPD +12 and ignores 18% DEF; after the Ultimate, DMG +60% until the start of the next turn.
On the Fall of an Aeon
5★
Best free-to-play option (S5): ramping ATK and a DMG buff on Weakness Break, which his Physical implant makes easy. Its buffs don't tick down while he is transformed.
Each attack grants +8% ATK for the battle (up to 4 stacks), and breaking a Weakness grants +12% DMG for 2 turns.
Something Irreplaceable
5★
Clara's signature: he is hit constantly during his transformation, so its DMG buff is always up.
ATK +24%; defeating an enemy or being hit heals 8% of ATK and grants +24% DMG until the end of the next turn.
A Trail of Bygone Blood
4★
Best 4★ (Battle Pass, S5): CRIT Rate and Skill/Ultimate DMG. Outperforms Aeon if you struggle to reach the CRIT Rate cap without Sunday.
CRIT Rate +12%, and Skill and Ultimate DMG +24%.
Under the Blue Sky
4★
4★ fallback: ATK% and CRIT Rate after defeating an enemy.
ATK +16%, and defeating an enemy grants +12% CRIT Rate for 3 turns.
Relics
As Navigator Isee Sees It
×4
His new best in slot by a small margin: Skill and Ultimate DMG stacks that don't fall off during his Ultimate. Best with Cerydra, Cyrene or his E2.
Set effects
2pIncreases ATK by 12%.
4pWhen the wearer enters combat or uses Skill, the DMG dealt by their Skill and Ultimate increases by 18%, stacking up to 3 time(s). At the start of the wearer's turn or after using Ultimate, removes 1 stack(s) of this effect.
Wavestrider Captain
×4
His kit revolves around being targeted by allies, so Help stacks are trivial, and the 48% ATK lasts for most of his transformation.
Set effects
2pIncreases CRIT DMG by 16%.
4pWhen the wearer becomes the target of another ally target's ability, gains 1 stack of "Help," stacking up to 2 time(s). If there are 2 stack(s) of "Help" when the wearer uses their Ultimate, consumes all "Help" to increase the wearer's ATK by 48% for 1 turn(s).
Scholar Lost in Erudition
×4
Generic alternative: CRIT Rate and Skill/Ultimate DMG.
Set effects
2pIncreases CRIT Rate by 8%.
4pIncreases DMG dealt by Skill and Ultimate by 20%. After using Ultimate, additionally increases the DMG dealt by the next Skill by 25%.
Champion of Streetwise Boxing
×4
Usable: he is the only target during his transformation, so the set stacks almost instantly.
Set effects
2pIncreases Physical DMG by 10%.
4pAfter the wearer attacks or is hit, their ATK increases by 5% for the rest of the battle. This effect can stack up to 5 time(s).
Planar ornaments
Arcadia of Woven Dreams
×2
Best choice: he counts as alone during his transformation, so the bonus is maxed at 36%.
Set effects
2pWhen the number of ally targets on the field is not equal to 4, for every 1 additional/missing ally target, increases the DMG dealt by the wearer and their memosprite by 9%/12%, stacking up to 4/3 time(s).
Rutilant Arena
×2
Close alternative: most of his damage is Basic ATK and Skill DMG.
Set effects
2pIncreases the wearer's CRIT Rate by 8%. When the wearer's current CRIT Rate reaches 70% or higher, DMG dealt by Basic ATK and Skill increases by 20%.
Space Sealing Station

Teams
Recommended teams
Hypercarry
Sunday is his best Coreflame generator, Cerydra duplicates Foundation: Stardeath Verdict at full power, and Dan Heng's Souldragon stays attached to him during the transformation.
Sustainless
Cyrene's Ode to Worldbearing lets him stay transformed indefinitely, refreshing his extra turns and Scourge, while Robin • Summeretto can stack HP% for a big ATK buff.
Free-to-play
The Remembrance Trailblazer advances him and adds True DMG, Tingyun generates Coreflame through her buffs and Energy, and Lynx heals him.
Guide
How to play
How he works
- Coreflame (Talent). He gains 1 Coreflame each time any ability targets him (up to 3 can overflow past 12). When the ability comes from a teammate, he also gets +30% CRIT DMG for 3 turns. His Skill gives 2 Coreflame, his A2 gives 1 at the start of combat and 3 when the transformation ends, and his A4 gives 1 whenever a teammate's ability regenerates his Energy.
- Khaslana (Ultimate). Deploys the Territory "Ruinous Irontomb": teammates depart and can't act, all enemies gain a Physical Weakness, and Khaslana gets 8 extra turns at 60% of his base SPD, +80% ATK and +270% Max HP. He can't be knocked down, heals after each attack, and ends with a final hit on all enemies. Buffs he already has don't tick down during the transformation.
- Khaslana's kit. He starts with 4 Scourge. Creation: Bloodthorn Ferry (Enhanced Basic ATK) gains 2 Scourge; Calamity: Soulscorch Edict gains Scourge per enemy, makes all enemies act immediately while he takes 75% less DMG, then counters; Foundation: Stardeath Verdict consumes Scourge for bounces, with a big extra hit at 4 Scourge.
- After the transformation, all allies gain +15% SPD for 1 turn and his A6 adds +50% ATK (stacking twice).
Rotation
- Use his Technique to one-shot normal enemies; in combat it gives 25 Energy to allies, 2 Scourge and 1 Skill Point.
- Before transforming, use his Skill while supports (Sunday, Bronya, Robin • Summeretto, Cerydra) target him with buffs and action advances to reach 12 Coreflame fast.
- Transform right after your supports have buffed him — ideally during an ally's turn, which extends that ally's buffs by 1 turn.
- As Khaslana, alternate Scourge generation with Foundation: Stardeath Verdict at 4 Scourge.
Tips
- Build him 1 SPD faster than your action-advance supports (e.g. 136 / 135 / 134) to get extra Coreflame-generating actions; SPD does nothing during the transformation itself.
- He prefers no sustain at all, but his A4 gives +45% DMG for 4 turns when a teammate heals or shields him.
- He is at his best in single-target content; in AoE his damage spreads onto unwanted targets.
Strengths
- Simple and extremely powerful, especially in single-target fights
- Can be played without a sustain (and prefers it)
- Transformation gives huge durability, CC immunity and death resistance
- Keeps short-lived buffs for his whole transformation
- Good free-to-play teammate options
Weaknesses
- Team Energy and HP can struggle after several transformations in long fights
- Very reliant on strong relics
- Weaker in AoE, where his damage spreads onto unwanted targets
