Phainon Build Guide: Light Cone, Relics, Stats and Teams｜HSR

The legendary Phainon is gradually emerging from the shadows. It is said that Phainon's surname is Kaslana😲, which inevitably sets the minds of the Pioneers racing with speculation. As a new 5-star character soon to be implemented, Phainon has long been regarded as one of the "officially promoted" core characters😍 since the stage of internal intelligence leaks. Judging from the current showcase, Phainon is indeed a formidable character not to be underestimated, boasting both dazzling visual effects and impressive combat performance.

Today, LDShop brings you a comprehensive Build Guide for Phainon, covering Light Cones, Relics, Ornaments, and Stats. The content is very complete. Keep reading to build the strongest Phainon💪!

 

Phainon Overview

Rarity: ⭐⭐⭐⭐⭐｜Element: Physical｜Path: Destruction

Phainon is a physical destruction DPS. He gains his ultimate through targeted abilities used on him (instead of energy). Upon activation, he transforms into ██, entering an isolated state where he unleashes devastating damage with a new set of abilities.When conditions align, Phainon becomes a brokenly strong unit, obliterating enemies with overwhelming force. However, his rigid mechanics prevent him from being universally adaptable, making him a high-risk, high-reward pick.

Strengths	Limitations
Extremely High Damage Output: Boasts absurd skill multipliers and scaling, making him one of the most powerful damage dealers in the game. Stunning Animations: His ultimate form features visually impressive effects that enhance the impact of his attacks.	Action Value Constraints: His damage potential during his ultimate is restricted by the way his action values function. Linear Playstyle: His kit lacks flexibility, focusing purely on raw damage with minimal utility.

 

Phainon Trace Priority

Upgrading Hyacine's traces in the proper sequence is essential for maximizing her effectiveness. Considering her ultime's mechanics and ability, the following is the recommended order for trace priority:

• Ultime: Transforms into ██ and deploys Territory during transformation. Other teammates in the Territory becomes Departed and cannot take action, and all enemies gain Physical Weakness.
• Skill: Gains 2 point(s) of "Coreflame," dealing Physical DMG equal to 300% of Phainon's ATK to one designated enemy and Physical DMG equal to 120% of Phainon's ATK to adjacent targets.
• Talent: When "Coreflame" reaches 12 point(s), Ultimate can be activated. After reaching the max limit, up to 3 excess point(s) can be accumulated. When Phainon is the target of an ally or an enemy's ability, he gains 1 point of "Coreflame." When he is the target of an ally's ability, increases CRIT DMG by 30%, lasting for 3 turn(s).
• Basic ATK: Deals Physical DMG equal to 100% of Phainon's ATK to one designated enemy.

Priority:

Skill ＞ Ultimate ＞ Talent ＞ Basic ATK

 

Phainon Light Cone

Signature Light Cone

Thus Burns the Dawn

⭐⭐⭐⭐⭐

HP: 953｜ATK: 688｜DEF: 397

The wearer's base SPD increases by 12/14/16/18/20. When the wearer deals DMG, ignores 18% /21% /24% /27% /30% of target's DEF. After the wearer uses Ultimate, obtains "Blazing Sun,"which is removed at the start of the turn. When "Blazing Sun" is active, increases the wearer's DMG dealt by 18% /21% /24% /27% /30%.

Alternatives

Light Cones	Effect
⭐⭐⭐⭐⭐
	Dance at Sunset (limited): Greatly increases the wearer's chance of getting attacked and increases CRIT DMG by 36%/42%/48%/54%/60%. After the wearer uses Ultimate, receives 1 stack of Firedance, lasting for 2 turns and stacking up to 2 time(s). Each stack of Firedance increases the DMG dealt by the wearer's follow-up attack by 36%/42%/48%/54%/60%.
	Something Irreplaceable (standard): Increases the wearer's ATK by 24%/28%/32%/36%/40%. When the wearer defeats an enemy or is hit, immediately restores HP equal to 8%/9%/10%/11%/12% of the wearer's ATK. At the same time, the wearer's DMG is increased by 24%/28%/32%/36%/40% until the end of their next turn. This effect cannot stack and can only trigger 1 time per turn.
	On the Fall of an Aeon (F2P): When the wearer attacks, increases their ATK by 8%/10%/12%/14%/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%/15%/18%/21%/24%, lasting for 2 turn(s).
⭐⭐⭐⭐
	A Secret Vow (gacha): Increases DMG dealt by the wearer by 20%/25%/30%/35%40%. The wearer also deals an extra 20%/25%/30%/35%40% of DMG to enemies whose current HP percentage is equal to or higher than the wearer's current HP percentage.

 

Eidolons vs Light Cone

• Damage output: If Phainon is cultivated as a core physical destruction DPS, it is highly recommended to prioritize obtaining the Light Cone. The base speed increase, defense penetration, and "Blazing Sun" damage boost provided by the Light Cone are all key attributes that directly and significantly enhance Phainon's damage output. These features enable Phainon to enter a high-damage state more quickly in battle and maintain stable high damage against enemies with varying defense levels, better fulfilling the role of a destroyer DPS.
• Skill system enhancement: If Phainon's skill system is already relatively complete or if the player values the strategic and diverse performance of Phainon more, then obtaining the Eidolon is also a good choice. The additional turn speed and physical defense penetration when "Spark" reaches the limit, the transformation and countdown mechanism, skill level upgrades, and additional bonuses in the Eidolon can further enrich Phainon's combat playstyle. This allows Phainon to have more flexible strategies in different combat scenarios and enhance its overall combat value.

So, if resources are limited, it is recommended to prioritize obtaining the Light Cone, as it is more direct and crucial for enhancing Phainon's damage output, enabling Phainon to play the role of a destroyer DPS more quickly.

When Phainon's basic damage output capability is relatively stable and there are sufficient resources for further enhancement, the Eidolon can then be gradually obtained to improve its skill system and combat strategies.

 

Phainon Relics, Ornaments & Stats

Relic Sets

• Best Choice

Wavestrider Captain

2-Piece Bonus: Increases CRIT DMG by 16%.

4-Piece Bonus: 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).

His optimal 4-piece set would be the new 3.3 set, Wavestrider Captain, which grants 16% critical damage and 48% attack power. If you haven't obtained the 4-piece Waverider yet, given that there are cinq weeks to farm, I would prioritize acquiring a good 4-piece Waverider set in 3.3.

 

• Alternatives

Mix 2-piece Sets (Flex)
	Champion of Streetwise Boxing 2-Piece Bonus: Increases Physical DMG by 10%.
	Musketeer of Wild Wheat 2-Piece Bonus: ATK increases by 12%.

If you lack a good 4-piece set with optimal substats, you can mix two 2-piece bonuses for raw stats. This approach sacrifices the 4p effect but gives high base ATK and damage% – effective if your 4p piece substats are lacking.

 

Ornaments

• Best choice

Arcadia of Woven Dreams

2-Piece Bonus: When the number of ally targets on the field is not 4, for every 1 extra/missing ally target, increases the wearer’s and their memosprite’s DMG by 9%/12%, stacking up to 4/3 time(s).

 

• Alternatives

Rutilant Arena 2-Piece Bonus: 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%.
