Destruction
Physical5★Released: 01/07/2025 · v3.4 “I’m Phainon of Aedes Elysiae. Greetings. As fellow outlanders in Okhema, our meeting is surely fate’s design. Come. Maybe we’ll even have a chance to fight alongside each other in the future.”
Phainon is a Physical DPS who builds up Coreflame and then transforms. At 12 points, his Ultimate turns him into Khaslana: his teammates become Departed for a while, every enemy gains a Physical Weakness, and Phainon carries the fight on his own with huge damage multipliers. If you still don't have a Physical DPS for endgame content, he is well worth considering.
He fits best on accounts that already have Sunday and Bronya, since both advance his turn and help him stack Coreflame very fast. No premium 5-star supports yet? That's fine, Phainon still does well with easy-to-get teammates like Trailblazer (Remembrance) or Tingyun.
Phainon is a DPS who scales with ATK and CRIT stats. His Traces already give him a good amount of CRIT DMG, so go for CRIT Rate on his Body.

CRIT Rate is the main pick for Body, with CRIT DMG only as a backup. Boots depend on your turn-advance supports: if Sunday or Bronya already have 160 SPD or more, take ATK%, since they push Phainon to the front of the turn order themselves. If they have at least 134 SPD but not 160 yet, use SPD Boots so Phainon is faster than them and builds Coreflame quicker. With Cerydra on the team, her SPD buff lets you swap SPD Boots for ATK% without losing anything. For the Sphere, take Physical DMG Boost first and ATK% second.
If you are tuning Phainon to be 1 SPD faster than Sunday or Bronya, get SPD up to that point first, then go for CRIT. Keep in mind that SPD doesn't add damage during his transformation, because his Ultimate only uses his base SPD. SPD only helps him build Coreflame faster outside of it.
Level his Skill first, since most of his damage comes from it. The other three are close to each other. His Talent increases the buffs he gets from allies and when he transforms, and his Ultimate increases the damage of the final hit when his transformation ends. Basic ATK can wait because you will use his Skill much more often.
March to Oblivion gives 1 Coreflame at the start of battle and 3 Coreflame each time his transformation ends, so his next Ultimate comes sooner. Bide in Flames increases his DMG by 45% when a teammate heals him or gives him a Shield, and gives 1 Coreflame when a teammate regenerates his Energy. Shine with Valor gives 50% ATK when he enters battle and each time his transformation ends, stacking up to 2 times. All three are worth unlocking early.
E1 raises the base SPD inheritance ratio for Khaslana's extra turns and gives 50% CRIT DMG for 3 turns after he uses his Ultimate. E2 adds 20% Physical RES PEN, and each time Foundation: Stardeath Verdict consumes 4 Scourge he gets 1 extra turn. E4 gives 4 extra stacks of Soulscorch when he uses Calamity: Soulscorch Edict. E6 removes the cap on overflow Coreflame, gives 6 Coreflame at the start of battle and adds True DMG after each Foundation: Stardeath Verdict attack.
This team pairs Phainon with supports who advance his turn and restore his Energy. Robin • Summeretto advances his turn and Cerydra boosts his Skill DMG. Huohuo restores Energy and gives ATK, and her healing on Phainon also triggers Bide in Flames. Remember that the CRIT DMG buff from his Talent only kicks in when a teammate's ability targets Phainon.
Phainon spends most of the fight transformed, and his Departed teammates can't be hit, so this team drops the sustain slot entirely. Cyrene keeps him transformed longer, Cerydra heavily buffs his Enhanced Skill, and Robin • Summeretto advances his turn and boosts his ATK.
Sunday advances Phainon's turn, gives CRIT Rate and restores Energy, while Cerydra powers up his Enhanced Skill. Dan Heng • Permansor Terrae attaches his Souldragon to Phainon, and it stays on him during the transformation, so it keeps giving Shields and launching Follow-up ATKs. This team suits long, high-pressure fights because everyone stays safe even before Phainon transforms.
The trick here is to pick two supports whose buffs target Phainon alone. The memosprite charge of Trailblazer (Remembrance) keeps building even while Phainon is transformed. Tingyun gives him ATK and restores his Energy. Lynx handles sustain, and if you want to save Skill Points, swap her for Gallagher.
One of his best teammates. She repeats his Enhanced Skill at full power without using extra Scourge and buffs that attack massively. Her SPD buff also lets Phainon swap SPD Boots for ATK%.
One of the best turn-advance supports for Phainon, giving lots of Coreflame through his Skill, Ultimate and action advance. His CRIT Rate buff is much needed, since Phainon's best build lacks CRIT Rate sources.
She lets Phainon stay transformed almost indefinitely, refreshing his extra turns and recovering Scourge, and she adds CRIT buffs too. The catch is that her Ultimate comes up slowly without other Remembrance characters on the team.
Advances Phainon's turn. When he transforms, she leaves the field along with her countdown, so her built-up progress isn't lost, though her E1 won't work. She doesn't need any particular stats and can run HP% on all 4 main-stat slots to give Phainon a huge ATK boost.
Your replacement for Sunday if you don't have him. She targets Phainon every turn to give him an immediate action, worth up to 3 Coreflame. The 1-turn buff from her Skill also lasts through his whole transformation.
The Souldragon on Phainon isn't removed by his Ultimate, so it keeps giving Shields and launching Follow-up ATKs while he is transformed. The Shields also trigger Bide in Flames, which makes him a great pick for long fights.
Her Skill and Ultimate both target Phainon for Coreflame, and her Ultimate gives 2 points because it also regenerates his Energy, along with an ATK buff. Her healing triggers the 45% DMG boost from his Trace as well.
Very important in Apocalyptic Shadow, because Phainon's Toughness reduction is huge and gets even more out of her Weakness Break Efficiency. All of her buffs still work while he is transformed.
An easy-to-get turn-advance option. The Trailblazer gives less Coreflame than Bronya and Sunday, but in return gives Phainon a True DMG boost, a kind of multiplier he usually doesn't have yet.
The 4-star choice when you don't have premium supports. She helps him build Coreflame, gives ATK and restores Energy, and her buffs last long enough that she doesn't clash with Bronya if you run both.
Phainon doesn't use normal Energy. His Ultimate needs 12 points of Coreflame instead. His Skill gives 2 points each time. Whenever he becomes the target of anyone's ability, enemies included, he gains 1 point, and if it comes from a teammate he also gets a CRIT DMG boost for 3 turns. Energy regeneration from a teammate gives 1 more point. After hitting 12 you can still store up to 3 extra points, and when the transformation ends you get Coreflame back based on that excess.
His Ultimate transforms Phainon into Khaslana and deploys a Territory. His teammates become Departed and can't take action, and every enemy gains a Physical Weakness. Khaslana gets 8 Khaslana's extra turns with a fixed SPD equal to 60% of his base SPD, and buffs on him don't tick down during these turns. Khaslana is immune to Crowd Control debuffs and restores HP after each attack. When he takes a killing blow, he isn't knocked down: he restores HP and immediately launches his Final Hit, but its damage drops based on how many extra turns he has left. Normally the Final Hit fires automatically at the start of his last extra turn and hits all enemies. When the transformation ends, all allies get 15% SPD for 1 turn.
Khaslana gets 4 Scourge right away when he transforms. Foundation: Stardeath Verdict is his main attack: every Scourge it consumes adds 4 bounces on random enemies, and at 4 Scourge it adds one big hit split evenly across all enemies. Using it with fewer than 4 throws away a lot of damage, so it's best to gather 4 first.
You have two ways to refill Scourge. His Enhanced Basic ATK, Creation: Bloodthorn Ferry, gives 2. Calamity: Soulscorch Edict gives Scourge equal to the number of enemies on the field, then makes all enemies take action immediately. During that time Khaslana takes 75% less DMG, and he gains 1 stack of Soulscorch each time an enemy attacks or takes action. Once the last enemy finishes, he counters every enemy, and each Soulscorch stack adds 20% of the original multiplier to that Counter. Against 3 or more enemies (when letting them act early has no downside), Calamity is usually the better deal, while in a one-on-one fight you should use the Enhanced Basic ATK.
With Phainon in the team, your Max Technique Points go up by 3. His Technique, Beginning of the End, defeats normal enemies in the overworld right away, and it costs no points if it misses. When you enter battle with it, all allies regenerate 25 Energy and Phainon deals DMG to all enemies at the start of each wave. It also lets Bronya have her Ultimate ready after the first turn.
