Aventurine Build Guide 2026: Best Relics, Light Cones & FuA Teams
Complete Aventurine build guide for version 4.x. Covers DEF-scaling shields, Knight relics, F2P light cone options, follow-up attack synergy, and team compositions.
Overview
Aventurine is a 5★ Imaginary Preservation sustain who provides party-wide shields, debuff resistance, and follow-up attacks. He scales entirely off DEF, making him one of the easiest characters in the game to build.
He is widely considered the best sustain unit in the game for follow-up attack teams and remains a top-tier pick for all endgame content.
Role: Sustain (Shielder) Rarity: 5★ Element: Imaginary Path: Preservation
F2P Verdict: ✅ Excellent. Aventurine is complete at E0, has amazing 4-star light cone options (includes the best Preservation LC in the game), and requires only DEF substats. He's one of the most F2P-friendly 5-star sustains.
How His Kit Works (Simple Explanation)
- Skill: Provides a powerful team-wide shield that stacks. The shield scales off Aventurine's DEF.
- Basic ATK: Deals Imaginary DMG and applies a debuff.
- Talent (Follow-Up): When a shielded ally is attacked, Aventurine gains charge. At 7 charges, he unleashes a follow-up attack that applies debuffs and regenerates shields.
- Ultimate: Deals AoE Imaginary DMG and increases the team's CRIT DMG taken by enemies.
- A2 Trace: Increases Effect RES for the whole team based on Aventurine's own Effect RES.
Key takeaway: Stack as much DEF as possible. That's it. His shields scale with DEF, his damage scales with DEF, and his follow-up triggers when allies get hit.
Best Relic Sets
4-Piece: Knight of Purity Palace ★★★★★ (Best in Slot)
| Bonus | Effect |
|---|---|
| 2-Piece | DEF +15% |
| 4-Piece | Increases shield DMG absorption by 20% |
This set maximizes his shielding capability. The 4-piece bonus makes everyone's shields 20% bigger.
Alternative: 4-Piece The Ashblazing Grand Duke
- 2pc: FuA DMG +20%. 4pc: ATK + FuA DMG stacking.
- Use this for a sub-DPS Aventurine build if you have over-shield already from his signature LC.
2-Piece + 2-Piece Options
- 2pc Knight + 2pc Guard of Wuthering Snow (DEF + DEF%)
- 2pc Knight + 2pc Passerby (DEF + outgoing healing — hybrid if running him as solo sustain)
Planar Ornaments
| Set | Verdict |
|---|---|
| Belobog of the Architects ★★★★★ | Best in slot. +15% DEF. +15% more DEF if Effect RES ≥ 50% (easy to reach). |
| Broken Keel ✅ F2P | +10% CRIT DMG to whole team. +Effect RES. More team utility, less personal DEF. |
| Fleet of the Ageless | +8% ATK to whole team. Only use if you somehow have enough DEF without Belobog. |
Main Stats & Substats
Stat Priority
| Piece | Main Stat | Priority |
|---|---|---|
| Body | DEF% | ★★★★★ |
| Feet | SPD | ★★★★★ |
| Planar Sphere | DEF% | ★★★★★ |
| Link Rope | DEF% | ★★★★★ |
Substats Priority
- DEF% (this is everything — shield strength, damage, everything)
- SPD (target 134+ breakpoint)
- Effect RES (to 50%+ for Belobog set bonus)
- Flat DEF
Stat Breakpoints
| Stat | Target | Notes |
|---|---|---|
| DEF | 4000+ (4500+ ideal) | Maxes out his shield scaling |
| SPD | 134+ | Standard breakpoint for more actions |
| Effect RES | 50%+ (for Belobog) | 30%+ if using Broken Keel |
Best Light Cones
Premium Options
| Light Cone | Rarity | Note |
|---|---|---|
| Inherently Unjust Destiny | 5★ | Signature. Massive DEF + shield + team CRIT DMG buff. Best preservation LC in the game. |
| She Already Shut Her Eyes | 5★ | Bailu's LC. High energy + heal on hit. Decent alternative. |
F2P Options ✅
| Light Cone | Source | Verdict |
|---|---|---|
| Day One of My New Life (S5) 🏆 | Gacha (4★) / Battle Pass | Best F2P option. +All-Type RES for team + DEF. Absolutely cracked for survival. |
| Landau's Choice (S5) | Gacha (4★) | Increases aggro + DMG reduction. Solid for triggering more FuAs. |
| This Is Me! (S5) | Forgotten Hall | +DEF + damage on ultimate. Good hybrid option. |
| Destiny's Threads Forewoven | Gacha (4★) | Effect RES + shield strength. Decent placeholder. |
| Amber (S5) | Gacha (3★) | DEF% shield on ult. Budget option for early game. |
Tip: Day One of My New Life S5 is genuinely one of the best light cones in the game for any preservation unit. If you have it, Aventurine becomes virtually unkillable.
Trace Priority
| Trace | Priority | Why |
|---|---|---|
| Skill | ★★★★★ | Main shielding ability |
| Talent | ★★★★★ | Follow-up attack + shield refresh |
| Ultimate | ★★★★ | Damage + debuff |
| Basic ATK | ★★★ | Used frequently to generate SP |
Best Team Compositions
Aventurine fits into almost any team. He truly shines in follow-up attack compositions.
Premium FUA Team (S-Tier)
| Role | Character | Notes |
|---|---|---|
| DPS | Feixiao / Ratio | Main carry |
| Support | Robin | Best partner — FuA synergy + ATK buff |
| Sub-DPS | Topaz / Moze | Secondary FuA |
| Sustain | Aventurine | FuA shield engine — generates follow-ups constantly |
F2P Team ✅
| Role | Character | How to Get |
|---|---|---|
| DPS | Any DPS you own | Your choice |
| Support | Asta / Pela / Tingyun | ✅ Free |
| Sub-DPS | March 7th (Hunt) / Moze | ✅ Free |

|---|---|---|

| Support | Any buffer | — |
| Flex | Any sub-DPS | — |
| Sustain | Aventurine | Keeps everyone alive through everything |
Eidolons Worth
| Eidolon | Worth It? | Note |
|---|---|---|
| E0 | ✅✅ Must-have | Already a complete sustain at E0 |
| E1 | ❌ Skip | Minor shield upgrade — not needed |
| E2 | ✅ Nice | Skill grants extra shield + Effect RES to team |
| E6 | ❌ Not for F2P | Massive shield + CRIT buff — overkill |
Recommendation: E0 is all you need. Aventurine is already the best sustain in the game at E0.
Game Mode Performance
| Mode | Rating | Notes |
|---|---|---|
| Memory of Chaos (MoC) | ★★★★★ | S-tier. Shields make enemies irrelevant. |
| Pure Fiction (PF) | ★★★★ | A-tier. Good sustain, FuA helps clear. |
| Apocalyptic Shadow (AS) | ★★★★★ | S-tier. FuA synergy + debuff application. |

Final Verdict
Should you pull Aventurine as a F2P / light spender?
Absolutely yes — if you need a sustain. Aventurine is the best shielder in the game and one of the most comfortable characters to use. He's complete at E0, has excellent 4-star light cone options, and trivializes most endgame content. If you already have a strong sustain (Huohuo, Lingsha), he's less urgent — but he's still a top-tier pull.
Rating: 9.5/10 — pull recommendation: ✅ Strong Yes (especially for FuA teams)
