The arrival of Phainon in Honkai Star Rail has sparked intense debate among players: should you pull for his E1 (Eidolon 1) or invest in his S1 (Signature Light Cone)? As a 5-star Physical Destruction DPS with a unique Territory mechanic, making the right choice can dramatically impact your damage output and overall team performance.
The short answer: Prioritize Phainon’s S1 over his E1. Here’s why this decision will maximize your investment and transform your gameplay experience.

Understanding Phainon’s Unique Mechanics
Phainon is a 5-star Physical Destruction character whose role in a team composition is that of the main DPS, but what sets him apart is his Territory mechanic. Phainon stands as Honkai: Star Rail’s most unique Physical Destruction DPS, utilizing Territory mechanic that departs allies for eight solo turns.
This unique transformation into “Khaslana” form makes base SPD incredibly valuable, as it directly affects his Territory duration and action frequency during his Ultimate state.

Phainon S1: Thus Burns the Dawn Analysis
Buff Type | Effect | Impact Level |
---|---|---|
Base SPD Boost | +12 SPD | Critical |
DEF Ignore | 18% Enemy DEF Shred | High |
DMG Multiplier | 60% DMG Boost (Post-Ultimate) | Very High |
Khaslana Inheritance | 60% Base SPD Transfer | Game-Changing |
Thus Burns the Dawn is currently the only Destruction Light Cone that provides a base SPD buff in the game, making it exceptionally valuable for Phainon’s kit. The 12 base SPD increase isn’t just about action frequency – it’s about maximizing his Territory duration and Khaslana form effectiveness.
The 18% DEF shred works multiplicatively with other damage bonuses, while the 60% DMG boost after Ultimate activation significantly amplifies his already impressive multipliers.
Phainon E1: Eidolon 1 Breakdown
Phainon’s E1 offers these enhancements:
- Base SPD inheritance increases from 60% to 66%
- Each defeated enemy boosts inheritance by 1.5% (up to 84% total)
- 50% CRIT DMG increase for 3 turns after Ultimate
While these buffs sound impressive, they’re situational and provide smaller immediate returns compared to his signature Light Cone.
The Mathematical Advantage: Why S1 Wins
The key factor lies in Phainon’s Territory mechanic calculation. Phainon’s territory duration for his Ultimate is calculated based on his base SPD only and does not take into account SPD substats on relics, SPD boots, or SPD buffs provided by teammates.
This means the 12 base SPD from his signature Light Cone directly translates to more actions during his most powerful state, while E1’s conditional benefits require specific scenarios to shine.

Investment Priority for Different Player Types
F2P Players: Definitely prioritize S1. The guaranteed power spike from his signature Light Cone provides more consistent value than E1’s conditional benefits.
Light Spenders: Get S1 first, then consider E1 if you have extra resources and frequently face multiple enemies.
Whales: Secure S1 immediately, then pursue E1 and beyond for maximum optimization.
Alternative Light Cone Options
If you decide against pulling for Thus Burns the Dawn, consider these alternatives:
- The Unreachable Side (Destruction) – Solid ATK% and CRIT DMG boost
- Something Irreplaceable (Destruction) – Good for sustained damage scenarios
- On the Fall of an Aeon (Destruction) – F2P-friendly option with decent scaling
However, none of these provide the base SPD crucial for Phainon’s unique mechanics.
Long-term Account Impact
Investing in Phainon’s S1 creates lasting value beyond just this character. 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.
The signature Light Cone remains relevant throughout the character’s lifespan, while Eidolons become less impactful as power creep occurs and new DPS characters emerge.

Making the Final Decision
Consider your current roster and resources. If you’re building Phainon as your primary Physical DPS, his S1 provides the foundation for his damage ceiling. E1 is luxury optimization that shines in specific scenarios but isn’t essential for his core functionality.
The official Honkai Star Rail website provides detailed character information and banner schedules to help you plan your pulls effectively.
Your investment should align with your gameplay goals and resource availability, but the mathematical advantages of S1 make it the clear winner for most players seeking maximum efficiency.

Frequently Asked Questions
Q: Can Phainon function effectively without his signature Light Cone?
A: While Phainon can work with alternative Light Cones, his signature weapon “Thus Burns the Dawn” provides irreplaceable base SPD that directly enhances his Territory duration and overall damage output. The 12 base SPD, 18% DEF ignore, and 60% DMG boost make it his best-in-slot option by a significant margin.
Q: Is it worth getting both E1 and S1 if I have the resources?
A: If you have abundant resources, getting both E1 and S1 maximizes Phainon’s potential. However, prioritize S1 first as it provides more consistent and impactful benefits. E1’s conditional buffs (66% SPD inheritance and enemy defeat bonuses) shine in multi-enemy scenarios but aren’t essential for his core performance in most content.
