Phainon is a Physical Element Character that follows the Path of Destruction. He becomes an extremely powerful DPS when in his Enhanced Stateâcapable of tanking, drawing aggro, countering, and unleashing a devastating amount of damage. His kit revolves around stacking Coreflame to activate this state via his Ultimate, which requires him to draw in all buffs, debuffs, and enemy attacks onto himself. This playstyle makes him a strong fit for Hypercarry teams featuring multiple Harmony characters.
Best Cavern Relics
(2) Increases CRIT DMG by 16%.
(4) When 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).
Phainonâs best relic set, when paired with two Harmony characters in the team, allows him to quickly max out the âHelpâ stack. Once his Ultimate is unleashed, this grants a 48% ATK bonus that lasts until the end of his Khaslana Mode (Enhanced State).
(2) Increases CRIT Rate by 8%.
(4) Increases DMG dealt by Skill and Ultimate by 20%. After using Ultimate, additionally increases the DMG dealt by the next Skill by 25%.
This set is relatively decent for Phainon, as it permanently increases his Skill and Ultimate DMG by 20%. Additionally, it boosts the DMG of his next Skill by 25% after using his Ultimate.
(2) Increases Physical DMG by 10%.
(4) After 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).
This set is worth considering, as it improves Phainonâs Physical DMG by 10%. Its ATK% stacking effect, however, requires him to be hit by enemies up to 5 times, making it slower to build and more effective in battles with multiple enemies. Regardless, the stacks do not disappear unless Phainon takes fatal damage or the battle ends.
Best Planar Ornaments
(2) When there are currently more or less than 4 ally targets in battle, each additional/missing ally target increases the wearer and their memosprite's DMG by 9%/12%, up to a maximum of 4/3 stacks.
The Arcadia of Woven Dreams is tailor-made for Phainon, as this setâs buff reaches maximum stacks upon his Ultimate activation.
(2) Increases the wearer's CRIT Rate by 8%. When the wearer's current CRIT Rate reaches 70% or higher, the wearer's Basic ATK and Skill DMG increase by 20%.
This set essentially increases Phainonâs CRIT Rate but requires him to have at least 70% to activate its Basic and Skill DMG bonuses. A CRIT Rate Body piece and decent CRIT Rate substats make this easy to achieve.
(2) Increases the wearer's ATK by 12%. When the wearer's SPD reaches 120 or higher, the wearer's ATK increases by an extra 12%.
This set is simple to use with straightforward buff mechanics, and it suits Phainon well since it increases his ATK as long as his SPD is 120 or higher.

Best Light Cones
SourceLight Cone Event Warp
Dispossession
The wearer's base SPD increases by 12~20. When the wearer deals DMG, ignores 18~36% of the target's DEF. After the wearer uses Ultimate, obtains "Blazing Sun," which is removed at the start of their turn. While "Blazing Sun" is in possession, increases the wearer's DMG dealt by 60~132%.This is Phainonâs signature 5â
Light Cone. It initially allows him to ignore the enemyâs DEF. Upon activating his Ultimate, Phainon deals 60% more DMG, making his Khaslana Mode significantly more powerful.
Moth To Flames
When the wearer attacks, increases their ATK by 8~16% in this battle. This effect can stack up to 4 time(s). After the wearer breaks an enemy's Weakness, increases DMG dealt by 12~24%, lasting for 2 turn(s).This LC is a free-to-play (F2P) option that is easily redeemable via the Herta Store. It boosts ATK and also provides bonus DMG when Phainon triggers a Weakness Break.
Massacre
Increases the wearer's CRIT Rate by 12~20%. The Skill DMG and Ultimate DMG dealt by the wearer increases by 24~40%.This can be obtained by purchasing the Nameless Honor at level 30. It provides CRIT Rate and boosts both Skill and Ultimate DMG.

Kinship
Increases the wearer's ATK by 24~40%. When the wearer defeats an enemy or is hit, immediately restores HP equal to 8~12% of the wearer's ATK. At the same time, the wearer's DMG is increased by 24~40% until the end of their next turn. This effect cannot stack and can only trigger 1 time per turn.This is comparatively decent for Phainon. It initially boosts his ATK, restores HP, and buffs his DMG until the next turn whenever he defeats an enemy. However, defeating enemies in consecutive actions does not stack these effects.
SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp
Rye Under the Sun
Increases the wearer's ATK by 16~32%. When the wearer defeats an enemy, the wearer's CRIT Rate increases by 12~24% for 3 turn(s).This LC buffs Phainonâs ATK and increases his CRIT Rate for 3 turns after he defeats an enemy. The CRIT Rate effect is easily triggered when fighting multiple enemies.
