Phainon Build Guide 2026: Best Relics, Light Cones & Remembrance Teams
Complete Phainon build guide for version 4.x. Covers best relic sets, planar ornaments, F2P light cone options, summon team compositions, and stat targets.
Overview
Phainon is a 5★ Physical Remembrance DPS and one of the strongest damage dealers in the current meta. He fights alongside his memosprite, dealing massive physical damage through coordinated attacks and summon-enhanced abilities.
As the first premium Physical Remembrance DPS, he has set the standard for the summon playstyle and remains a top-tier pull target.
Role: Main DPS Rarity: 5★ Element: Physical Path: Remembrance
F2P Verdict: ✅ Solid. He has free Herta Store light cone options (Victory In a Blink), free teammates (Remembrance Trailblazer), and performs well at E0. His best team wants Sunday, but he's still strong without.
How His Kit Works (Simple Explanation)
- Memosprite: Phainon summons a memosprite that fights alongside him. The memosprite has its own turn and actions.
- Skill: Deals Physical DMG to a single target and boosts the memosprite's next attack.
- Ultimate: Both Phainon and his memosprite unleash powerful AoE Physical DMG. Grants a damage buff state.
- Talent: Coordinated attacks — when Phainon attacks, his memosprite may follow up, and vice versa.
- Memosprite Skill: The memosprite's own attack, which scales off Phainon's stats and deals splash Physical DMG.
Key takeaway: Build Phainon as a standard CRIT DPS. Speed tune him with Sunday for maximum actions. His memosprite inherits his stats, so focus on CRIT and ATK.
Best Relic Sets
4-Piece: Poet of Mourning Collapse ★★★★★ (Best in Slot)
| Bonus | Effect |
|---|---|
| 2-Piece | Increases Quantum DMG by 10% (note: the 2-piece is suboptimal for Phainon) |
| 4-Piece | When wearer's SPD is ≤ 95, CRIT Rate increases by 32% |
Despite the mismatched 2-piece, the 32% CRIT Rate from the 4-piece is too valuable to pass up. It frees nearly all your substats for CRIT DMG and ATK%. This requires running no SPD substats and ATK% boots.
Alternative: 4-Piece The Scholar Lost in Erudition
- CRIT Rate + Skill/Ultimate DMG boost
- Works if you don't want the SPD restriction of Poet
- Requires standard SPD boots setup
2-Piece + 2-Piece Options
- 2pc Longevous Disciple + 2pc Musketeer (HP% + ATK%)
- 2pc Duke + 2pc Musketeer (FuA + ATK%)
- Use while farming Poet
Planar Ornaments
| Set | Verdict |
|---|---|
| Bone Collection's Serene Demesne ★★★★★ | Best in slot. +12% HP. +28% CRIT DMG (easy to trigger with 5000+ HP). |
| The Wondrous BananAmusement Park ✅ F2P | +48% CRIT DMG while memosprite is active. Strong option while farming Bone Collection. |
| Firmament Frontline: Glamoth | +12% ATK. CRIT DMG boost at 135/160 SPD breakpoints. Only good if you're running SPD boots. |
Main Stats & Substats
Stat Priority (Poet Build)
| Piece | Main Stat | Priority |
|---|---|---|
| Body | CRIT DMG | ★★★★★ |
| Feet | HP% (poet build) / SPD (scholar build) | ★★★★★ |
| Planar Sphere | Physical DMG% | ★★★★★ |
| Link Rope | ATK% | ★★★★★ |
Substats Priority
- CRIT DMG (aim for 220%+ with Poet)
- CRIT Rate (need ~68% from substats with Poet 4-piece)
- ATK%
- Flat ATK
Stat Breakpoints (Poet Build)
| Stat | Target | Notes |
|---|---|---|
| CRIT Rate | 100% in combat | Poet gives 32%, need ~68% from substats |
| CRIT DMG | 200%+ (240%+ endgame) | Scales all damage |
| SPD | Base (Poet) or 134+ (Scholar) | Do NOT add SPD to Poet build |
| ATK | 3200+ | Standard DPS target |
Best Light Cones
Premium Options
| Light Cone | Rarity | Note |
|---|---|---|
| Flames of the Netherwing | 5★ | Castorice's signature — actually great on Phainon too for the HP and CRIT DMG |
| Yet Hope is Priceless | 5★ | Strong CRIT-based remembrance LC |
| A Grounded Ascent | 5★ | Sunday's LC — viable offensive option |
F2P Options ✅
| Light Cone | Source | Verdict |
|---|---|---|
| Victory In a Blink (S5) 🏆 | Herta's Store | Best F2P option. +CRIT DMG. Free and effective. |
| Reminiscence | Gacha (4★) | Decent CRIT stats. Good placeholder. |
| The Birth of the Self | Gacha (4★) | Viable in AoE-heavy content. |
| Passkey | 3★ | Budget option — only if you have nothing else. |
Tip: Victory In a Blink S5 from Herta's Store is a completely viable option. Phainon performs great even without a limited 5★ LC.
Trace Priority
| Trace | Priority | Why |
|---|---|---|
| Skill | ★★★★★ | Main damage + memosprite boost |
| Memosprite Skill | ★★★★★ | Memosprite's primary attack |
| Ultimate | ★★★★★ | Burst damage + state buff |
| Talent | ★★★★ | Coordinated attack synergy |
| Memosprite Talent | ★★★★ | Memosprite utility |
| Basic ATK | ★☆☆☆☆ | Almost never used |

Final Verdict
Should you pull Phainon as a F2P / light spender?
Yes. Phainon is a top-tier Physical DPS with strong F2P options. He works with free teammates, has a good Herta Store light cone, and performs at the highest level with or without limited supports. His only real "need" is Sunday for max performance, but RMC is a completely viable substitute.
Rating: 9/10 — pull recommendation: ✅ Strong Yes
