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.
Under the Blue SkyUnder the Blue Sky supplies ATK and grants CRIT Rate after the wearer defeats an enemy.
When to use it : Use when the character can maintain the CRIT Rate buff by defeating enemies regularly.
Relics
Wavestrider Captain converts repeated ally targeting into CRIT DMG and ATK for Phainon's solo burst.
When to use it : Have allies target Phainon at least twice before Ultimate so Wavestrider's support-triggered stacks cover Transformation.
Two-piece Scholar Lost in Erudition plus two-piece Musketeer of Wild Wheat is a transition mix: Increases CRIT Rate by 8%. Increases ATK by 12%.
It reuses strong pieces from two sets while a complete four-piece configuration with equivalent main stats and substats is still being farmed.
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.
Firmament Frontline: Glamoth is a ranked alternative with this two-piece effect: Increases the wearer's ATK by 12%. When the wearer's SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG.
When to use it : Reach at least 135 SPD; 160 SPD unlocks the set's maximum DMG 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Phainon accumulates 12 Coreflame, transforms into Khaslana and takes eight extra turns while the other allies enter Withdrawn.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- 2Apply Cerydra, Sunday and sustain buffs before using Ultimate, because those allies then become Withdrawn.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.
