Light Cone
Thus Burns the DawnThus Burns the Dawn adds 12 base SPD, ignores 18% DEF and grants 60% DMG after Phainon enters his Ultimate sequence.
When to use it : Enter Transformation only after support buffs are applied so the cone's defensive bypass and Ultimate DMG cover Khaslana's sequence.
On the Fall of an AeonOn the Fall of an Aeon offers stackable ATK and a Break-triggered DMG bonus through Phainon's long Transformation sequence.
It is permanently available from Herta's Store and reaches S5 without limited Warps.
Something IrreplaceableSomething Irreplaceable adds ATK and restores HP after defeating an enemy, making it a conditional owned standard alternative rather than a Transformation staple.
When to use it : Use only when already owned and when defeating enemies can trigger its post-defeat damage bonus.
A Secret VowA Secret Vow is the four-star non-Battle-Pass fallback, giving broad DMG and more when Phainon's HP percentage is not above the target's.
When to use it : Its extra damage requires the enemy's current HP percentage to be at least Phainon's current HP percentage.
Relics
As Navigator Isee Sees It stacks Skill and Ultimate DMG quickly when Cerydra duplicates Phainon's Skills.
When to use it : Use Skills and Cerydra's duplicated Skills to reach three stacks; one stack is removed at turn start and after Ultimate.
Wavestrider Captain converts repeated ally targeting into CRIT DMG and ATK for Phainon's solo burst.
When to use it : Have allies target Phainon twice before his Ultimate, then use Ultimate during his turn to extend the four-piece ATK window.
Scholar Lost in Erudition offers unconditional CRIT Rate plus Skill and Ultimate damage for a lower-setup option.
When to use it : Use when repeated ally targeting cannot maintain Wavestrider Captain's four-piece condition.
Planar Ornaments
Arcadia of Woven Dreams rewards the ally withdrawal built into Khaslana's solo Transformation.
When to use it : Use Phainon as the sole active combatant during Transformation to activate Arcadia's strongest state.
Rutilant Arena adds CRIT Rate and strengthens the Basic and Skill damage that make up most of Phainon's Transformation.
When to use it : Reach 70% CRIT Rate before counting its Basic ATK and Skill bonus.
Team lineup
Cerydra duplicates Phainon's Skill through Coup de Main, Sunday accelerates and buffs him, and Permansor Terrae supplies pre-Transformation protection.
When to use it : Cerydra and Sunday must target Phainon before Ultimate; apply Permansor Terrae's protection before all three supports withdraw.

Phainon accumulates 12 Coreflame, transforms into Khaslana and takes eight extra turns while the other allies enter Withdrawn.
How to play it
- 1Let allies target Phainon and restore his Energy to build Coreflame; up to three excess points carry into Transformation.
- 2Apply Cerydra, Sunday and sustain buffs before using Ultimate, because those allies then become Withdrawn.
- 3During Khaslana, alternate Soulscorch and Stardeath enhanced attacks across the eight extra turns according to target count and resources.
Sources and methodology
Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.
Review method
Prydwen and Icy Veins were read independently, then checked against released local 4.4 data. The model requires 12 Coreflame, allows three overflow, applies allied buffs and healing/shielding before Withdrawn, then resolves Khaslana's eight 60%-base-SPD extra turns. Soulscorch and Stardeath are treated as distinct enhanced attacks. Sunday's external 20% CRIT Rate is included only in the effective cap.
