HSR Aventurine Build Guide — Best Light Cones, Relics & Teams (4.4 Rerun)

The Aventurine build every Trailblazer wants before his rerun is simpler than it looks, because his entire kit is built on one stat: DEF. Aventurine is the 5-star Imaginary Preservation unit whose original banner returns in Honkai: Star Rail Version 4.4 Phase 2 on August 5, 2026, and he remains the most flexible shielder in the game precisely because he never asks you to choose between defence and damage. Stack DEF and you get both a wall that keeps your team alive and a follow-up attacker that actually contributes. This guide is for both the Trailblazer building their first dedicated sustain and the veteran who wants Aventurine tuned for a follow-up damage team, so you know what to farm and how to slot him before Gilded Imprisonment goes live.

One clarification up front, because the name is now crowded: this guide covers the original Imaginary Preservation Aventurine, not the newer Quantum DPS reimagining. If you are chasing the Quantum carry, that is a different unit with a different build; this piece is about the shielder returning in 4.4.

📅 Rerun Banner Status — Gilded Imprisonment, August 5

Aventurine's rerun, the Gilded Imprisonment banner, runs in Phase 2 of Version 4.4 from August 5 to August 25, 2026, alongside the Indelible Coterie half of the patch. His 4-star rate-ups are Moze, Hanya, and Serval, and his signature Light Cone becomes available at the same time on the paired Coalesced Truths banner. That timing is the single most useful planning fact, because it tells you exactly when to have your Stellar Jade ready and whether to grab the Light Cone in the same window.

If Aventurine is your target, the Phase 2 slot gives you the whole first half of 4.4 to bank pulls, so you arrive at his banner with a real budget rather than scraping. It also means you can watch how your account handles current endgame before committing, then decide whether you need his signature cone or can lean on a free alternative, which we cover below.

⚔️ How Aventurine Works — Everything Scales Off DEF

Aventurine is a shielder first and a follow-up sub-DPS second, and both halves run on the same engine. His Skill applies a Fortified Wager shield to the whole team that scales off his DEF, so the more defence you build, the sturdier the shield. That already makes DEF his primary stat, but his Talent takes it further: while shielded, allies gain CRIT Rate, and Aventurine himself converts DEF into his own combat CRIT Rate. Because of that conversion, building DEF does not cost you damage the way it would on any other character; it is the thing that turns his follow-up hits into real numbers.

The follow-up damage comes from his Talent's counters and his Ultimate. When allies attack shielded enemies or trigger the right conditions, Aventurine unleashes Blind Bet follow-up attacks, and his Ultimate raises the whole team's CRIT DMG while boosting his own damage. In plain terms: he shields the team, the shields buff the team's crit, and his own follow-up attacks add a steady trickle of Imaginary damage on top. That is why he fits both roles at once, and why a single DEF-focused build serves a defensive comp and an aggressive one without re-gearing.

The design choice that shapes everything is the DEF-to-CRIT conversion, so your build is really a project to pile on as much DEF as possible while hitting a couple of supporting breakpoints. Get that right and Aventurine crits reliably from defensive stats alone, freeing your relic substats from the usual CRIT Rate hunt.

🔮 Best Light Cones

His signature is the clear ceiling, but the free options are unusually strong, so nobody should feel locked out.

• Inherently Unjust Destiny (5-star signature): the best-in-slot choice. It strengthens his shields and boosts his follow-up damage, and his follow-up attacks gain a chance to increase the damage the target takes for two turns, which quietly buffs your carry. If you plan to run Aventurine in a follow-up team, this is worth grabbing on the paired banner.
• Moment of Victory (5-star): a superb non-signature pick that raises his DEF, increases his own aggro so he tanks hits for the team, and adds Effect RES. Because it feeds DEF directly, it plays straight into his scaling.
• Trend of the Universal Market (4-star, free): the standout budget option and available from the Herta shop. It grants a bonus shield and a chance to counterattack, so it doubles down on exactly what Aventurine already does. Most F2P Trailblazers run this and never feel undergeared.
• Concert for Two or Destiny's Threads Forewoven (4-star): serviceable fallbacks that provide shield or DEF value if the above are unavailable.

The takeaway is that Aventurine's signature adds meaningful team damage through the vulnerability effect, but Trend of the Universal Market covers his defensive job almost completely, so prioritise the cone only if you are optimising a follow-up carry around him.

💎 Best Relics and Planar Ornaments

Your relic choice depends on which half of his kit you are leaning into, and both are valid:

• 4-piece Knight of Purity Palace: the pure-sustain build. It boosts DEF and raises the maximum shield your team can absorb, so it is the safest pick for hard content where survival is the whole job.
• 2-piece Pioneer Diver of Dead Waters + 2-piece Knight of Purity Palace: the balanced hybrid, giving both a shield boost and a damage bump against debuffed enemies. This is the default for most accounts because it keeps him tanky while letting his follow-up hits matter.
• 4-piece Pioneer Diver of Dead Waters: the follow-up sub-DPS build. Pioneer increases his damage to debuffed enemies and grants extra CRIT Rate and CRIT DMG based on how many debuffs the target carries, so it pays off in teams that stack debuffs and lets him double as a damage source.

For Planar Ornaments, Broken Keel is the standard choice: hitting 30% Effect RES grants the whole team a flat CRIT DMG boost, which turns Aventurine's defensive stat sheet into a team-wide damage buff. If you are building him as a genuine follow-up attacker, Duran, Dynasty of Running Wolves is the aggressive alternative, stacking damage as your team lands follow-up hits.

📊 Stat Priority and Breakpoints

Because everything routes through DEF, your main stats and substats point the same direction:

1. Body: DEF%
2. Feet: DEF% for most builds, or SPD boots if you need to hit a speed tuning target
3. Planar Sphere: DEF%
4. Link Rope: Energy Regeneration Rate to keep his Ultimate online, or DEF% if your energy is already covered

Substats prioritise DEF%, then Effect RES (to reach the Broken Keel threshold), then SPD. The two numbers worth chasing: aim for around 4,000 DEF in combat, which pushes his self-generated CRIT Rate toward 48% so his follow-ups crit without dedicated crit substats, and target at least 134 SPD so he acts twice per cycle and refreshes shields before they lapse. Hit those two and the rest of the sheet can be messy without hurting his performance, which is what makes him so forgiving to gear.

👥 Best Teams

Aventurine's ceiling is highest in follow-up damage teams, but his floor is "any team that needs a shield," and that range is his real selling point.

• Follow-up hypercarry: pair him with a follow-up-attack carry such as Feixiao or Dr. Ratio, add a matching support, and let his Blind Bet counters and CRIT buffs stack with the carry's own follow-up rhythm. This is where his signature cone and Pioneer Diver set earn their keep.
• Counter and crit-value teams: with a unit like Yunli that thrives on counterattacks, Aventurine's shields keep the counter windows open while his team-wide CRIT DMG buff amplifies every hit.
• Universal sustain: for any team lacking a healer or shielder, Aventurine drops in as a pure Knight of Purity Palace wall. Because his shields cover the whole team and scale off his own gear rather than the carry's, he never competes for buffs, which is why he stays relevant patch after patch.

The through-line is that Aventurine rarely asks the team to build around him; he adapts to what the team already does, adding survivability plus a little damage instead of demanding a slot be reshaped for him.

🎯 Investment Value — How Far to Take Him

As a build, Aventurine is complete at Eidolon 0 with a solid DEF relic set, so you do not need copies to make him work. His Eidolons sharpen the follow-up damage and add energy and CRIT value, which matters most if you are running the dedicated Pioneer Diver carry build, but they are luxuries rather than requirements. For the vast majority of Trailblazers, E0 with Trend of the Universal Market or Moment of Victory clears every piece of endgame content the game currently throws at you.

The one upgrade that changes his output rather than just padding it is the signature Light Cone, because the target-vulnerability effect buffs your carry, not just Aventurine. If you are pulling him mainly to shield a follow-up team you have already invested in, the cone is the piece to consider on the Coalesced Truths banner; if you want him as a universal sustain, skip it and save. For the wider patch context, our HSR 4.4 Everything New breakdown lays out the full banner order, and if you are gearing a carry to pair him with, the Himeko Nova build guide and Gilgamesh build guide cover two of the patch's headline damage dealers.

💡 Build Checklist Before His Banner

To have Aventurine ready the moment Gilded Imprisonment opens on August 5:

1. Farm a DEF% main-stat relic set now, targeting Knight of Purity Palace for sustain or Pioneer Diver pieces for the follow-up build.
2. Secure a Broken Keel planar and push your Effect RES toward 30% to unlock the team CRIT DMG buff.
3. Grab Trend of the Universal Market from the Herta shop if you do not have a 5-star cone, so he is fully functional on day one.
4. Decide his role: pure shielder or follow-up sub-DPS, because that single choice determines whether you chase the signature cone and Pioneer Diver set.
5. Tune him toward 4,000 DEF and 134 SPD, then stop worrying about the rest of the substats.

To stress-test the build once he is yours, our 4.4 Anomaly Arbitration guide is a useful benchmark for how a well-geared sustain holds up in current endgame.

Aventurine's rerun is a short window, and a shielder this universal earns his slot across nearly every account. Trailblazers who want him built and battle-ready without the relic grind can explore trusted Honkai: Star Rail Accounts with the DEF sets already farmed, accelerate every Relic and Stellar Jade run with expert Honkai: Star Rail Hourly Services, or clear Memory of Chaos, Pure Fiction, and Apocalyptic Shadow through reliable Honkai: Star Rail Boosting.
