Phainon in Honkai: Star Rail 3.4: Leaked Kit, Eidolons, Light Cone, and Pre-Farming Guide

Phainon’s Leaked Kit Overview

Phainon is designed as a heavy-hitting hypercarry with a transformation gimmick that activates during his Ultimate, shifting him into a "Second Form" called The Chronosruin Irontomb. His kit revolves around stacking resources like Memory Points, Coreflame, Scourge, and Bruise to unleash devastating Physical damage. His Ultimate creates a unique territory, benches allies, and grants extra turns, making him a one-man army. Here’s a detailed breakdown of his kit based on the latest leaks:

Basic Attack

• Regular: Deals Physical DMG equal to 100% of Phainon’s ATK to a single enemy and grants 1 Memory Point.
• Enhanced (Creation: Bloodthorn Ferry): In Second Form, deals Physical DMG equal to 250% of ATK to a primary target and 75% of ATK to adjacent enemies, granting 2 Scourge stacks.

Skill

• Normal: Deals AoE Physical DMG based on ATK (exact multiplier not specified) and grants 2 Memory Points.
• Enhanced Skill 1: Forces all enemies to take their actions immediately, applies Ruin marks based on the number of enemies, heals Phainon, clears his debuffs, and sets up a Counter.
• Enhanced Skill 2 (Foundation: Stardeath Verdict): Consumes up to 4 Ruin marks to deal multiple hits of Physical Bounce DMG. Using all 4 marks triggers an additional AoE hit. Scales with ATK.

Ultimate

Phainon’s Ultimate consumes 12 Memory Points (not traditional Energy) to activate The Chronosruin Irontomb, transforming him into his Second Form for 8 extra turns at 60% of his base SPD (increases to 72% with Eidolon 1). During this state:

• Allies are removed from the battlefield.
• Phainon becomes immune to crowd control.
• All enemies gain a Physical Weakness.
• Attacks deal increased Toughness damage.
• Buffs last an additional turn.
• ATK increases by 40–80%, and Max HP increases by 120–270%.
• After attacking, Phainon heals for 20% of Max HP. If his HP would drop to zero, he heals for 25% of Max HP and triggers a Final Hit.
• When the mode ends (after 8 turns or if HP drops too low), Phainon unleashes a Final Hit dealing Physical DMG equal to 960% of ATK split across all enemies. If ended early, DMG decreases by 12.5% per unused turn. Allies return with a 15% SPD boost for 1 turn.

Talent

• Coreflame Stacks: Phainon gains Coreflame stacks when targeted by allied or enemy abilities or through his Traces. At 15 Coreflame stacks, his CRIT DMG increases for 2 turns.
• Second Form: Starts with 4 Bruise stacks. If transformed during an ally’s turn, their buffs gain an extra turn.
• Trace Buffs:
  • Trace 1: At battle start, gains 1 Ember point.
  • Trace 2: When healed or shielded by allies, DMG increases by 45% for 2 turns.
• Sustain: If Phainon would be knocked out, he heals for 25% of Max HP and triggers the Final Hit.

Technique

Costs 2 Technique Points (max 8). Clears all normal enemies nearby. Against Elites, allies gain Energy, and Phainon starts his territory with 2 extra Ruin marks.

Eidolons

• E1: Increases Second Form SPD to 72% of base SPD and adds 15% Physical Resistance Penetration at max Coreflame for 2 turns. For every enemy defeated, SPD increases by 1.5%, up to 84%. Upon using Ultimate, grants 50% CRIT DMG for 3 turns.
• E2: Second Form attacks deal 120% of their normal DMG. Consuming 4 Scourge stacks with Foundation: Stardeath Verdict grants an extra turn.
• E3: Increases Ultimate level by 2 (max 15) and Basic Attack by 1 (max 10).
• E4: Grants 4 Soulscorch stacks when using Calamity: Soulscorch Edict.
• E5: Increases Skill and Talent level by 2 (max 15).
• E6: Increases max Scourge by 2, adds 2 Scourge for Creation: Bloodthorn Ferry or Calamity: Soulscorch Edict, and makes Foundation: Stardeath Verdict deal 36% extra True DMG to the enemy with the highest HP.

Relic and Ornament Sets

• Relic Set: Captain Over Cursed Waves (Version 3.3):
  • 2-piece: 16% CRIT DMG.
  • 4-piece: Grants 1 Assist stack (up to 3) when an ally’s Skill targets Phainon, each stack boosting ATK by 16–48% during his Ultimate.
• Planar Ornament: Dusky Dawn Cliff (Version 3.4): Boosts CRIT Rate for 8 turns after using his Ultimate, addressing his low base CRIT Rate. Combined with his high ATK buffs (up to 60% from kit and Relics), this set optimizes his damage output.

HP Scaling in Phainon’s Kit

Phainon’s kit incorporates HP scaling, but it’s primarily for survivability, not damage. Here’s how it works:

• Max HP Boost: In Second Form, Phainon’s Max HP increases by 120–270%, making him exceptionally durable.
• Healing: After attacking in Second Form, he recovers 20% of Max HP. If he would be knocked out, he heals for 25% of Max HP and triggers the Final Hit.
• Damage Reduction: With Soulrending Blaze stacks, Phainon reduces incoming DMG by up to 75%, synergizing with his boosted HP.

However, his damage scales entirely with ATK, with multipliers ranging from 100–960% across his Basic Attacks, Skills, and Ultimate. Thus, prioritize ATK and CRIT stats for damage, while HP scaling ensures he stays alive during his solo Ultimate phase.

Phainon’s Signature Light Cone: Thus Burns the Dawn

Phainon’s signature Light Cone, Thus Burns the Dawn, is designed to enhance his hypercarry playstyle:

• Base Stats:
  • HP: 952.6
  • ATK: 687.96
  • DEF: 396.90
• Effects:
  • Increases base SPD by 12/14/16/18/20%, enabling faster actions and more turns during his Second Form.
  • When dealing DMG, ignores 18/21/24/27/30% of the target’s DEF, amplifying Physical damage output.
  • After using Ultimate, obtains the “Blazing Sun” effect, removed at the start of the next turn. While active, increases DMG dealt by 18/21/24/27/30%.
• Synergy: Tailored for Phainon’s ATK-scaling kit, the SPD boost maximizes action frequency, DEF ignore enhances damage, and the “Blazing Sun” buff spikes DPS during his Ultimate. This Light Cone is his best-in-slot option, significantly boosting his performance as a meta-defining DPS.

Team Synergy and Playstyle

Phainon excels as a hypercarry DPS, dominating during his Ultimate’s Chronosruin Irontomb phase, where he fights alone. His playstyle relies on building Memory Points and Coreflame stacks to trigger his Ultimate quickly and maximize damage. Ideal team compositions include:

• Harmony Supports: Sunday is his best partner, providing SPD buffs, Energy restoration, and targeted Skills to stack Coreflame and Assist stacks (from Relics). Other Harmony characters like Sparkle or Tribbie can also boost his ATK and action frequency.
• Sustain Units: Characters like Huohuo or Gallagher provide healing or shields to trigger Phainon’s Trace 2 DMG boost (45% for 2 turns).
• Sub-DPS or Buffers: Units like Silver Wolf (buffed in 3.4) can apply Physical Weakness or DEF shred to enhance Phainon’s damage.

During his Ultimate, Phainon’s solo nature means he doesn’t rely on ally actions, but pre-Ultimate support is crucial to stack resources. His high ATK scaling and CRIT DMG buffs make him a meta-defining DPS, potentially surpassing other top-tier characters.
