Imaginary
The PreservationThe premier shielder in Honkai: Star Rail. Aventurine provides stackable Fortified Wager shields to the entire party while unleashing a 7-hit follow-up attack that scales entirely off DEF. His Leverage trace converts DEF stacking into up to 48% CRIT Rate, making him both the best sustain and a genuine damage contributor.

Cornerstone Deluxe
Provides all allies with a Fortified Wager shield that blocks DMG equal to 16% of Aventurine's DEF plus 80, lasting for 3 turns. Repeatedly gaining Fortified Wager stacks the Shield effect, capped at 200% of the current Skill's shield value. Your primary action each turn to maintain team protection.

Roulette Shark
Randomly gains 1 to 7 points of Blind Bet. Inflicts Unnerved on a single target enemy for 3 turns and deals Imaginary DMG equal to 162% of Aventurine's DEF. While Unnerved is active, any ally who hits that enemy deals +9% CRIT DMG. A massive single-target burst that also bolsters the entire team's critical damage.

Shot Loaded Right
Increases Effect RES by 25% for a single ally with Fortified Wager. When that ally is attacked, Aventurine gains 1 Blind Bet point. When Aventurine has Fortified Wager he can resist Crowd Control debuffs (resets after 2 turns). Gains an additional Blind Bet after being attacked. At 7 Blind Bet points consumed, launches a 7-hit follow-up attack dealing Imaginary DMG equal to 12.5% DEF per hit to a random enemy. Blind Bet caps at 10 points.

After using the Technique, one of three effects is granted at random: a chance for DEF +24%, a high chance for DEF +36%, or a small chance for DEF +60%. When the Technique is used repeatedly, the highest buff value is retained. When the next battle starts, increases all allies' DEF by the rolled value for 3 turns.

Best Light Cones
#1
Inherently Unjust Destiny
His signature and clear best-in-slot. Provides a substantial shield strength bonus and grants an additional DMG bonus when Aventurine provides a shield to an ally, which he does constantly. Unmatched across all scenarios at any investment level.
#2
Moment of Victory
Excellent F2P-accessible alternative. Increases DEF and boosts shield strength, plus taunts enemies to attack the wearer, feeding Blind Bet generation from the Talent at an accelerated rate.
#3
Concert for Two
Strong limited option that stacks Shield DMG Absorb based on the number of shielded allies. Because Aventurine shields the whole party, this cone charges quickly and provides reliable sustained value.
#4
Day One of My New Life
Budget 4-star pick providing DEF and a team-wide DMG RES bonus when a shield is active. Solid value for the investment, especially early on before pulling better options.
#5
Destiny's Threads Forewoven
Provides DEF and reduces DMG taken by shielded allies. The passive fits Aventurine's playstyle naturally since his shields are always active, making this a reliable fallback option.
Best Relics
Cavern Sets
1
Knight of Purity Palace (4pc)
Best-in-slot cavern set by a wide margin. The 2-piece grants DEF% and the 4-piece boosts the maximum shield HP Aventurine can provide, directly scaling his primary function. No other cavern set competes when you need maximum shield output.
2
+
Knight of Purity Palace (2pc) + Messenger Traversing Hackerspace (2pc)
Mixed 2+2 option. The Messenger set grants Speed, helping Aventurine hit the 134 Speed threshold more easily while still keeping the Knight DEF bonus. Run this if you need Speed from substats elsewhere.
3
Pioneer Diver of Dead Waters (4pc)
Offensive alternative when Aventurine is specifically built for maximum follow-up damage output. The 4-piece boosts CRIT stats against debuffed targets. Only consider if your Knight pieces have poor substats and your Pioneer set has significantly better rolls.
Planar Ornament Sets
1
Broken Keel
Best planar set for Aventurine. Provides Effect RES and, when Aventurine's Effect RES reaches 30% or higher, grants all allies +10% CRIT DMG. His Talent already gives him 25% Effect RES, so hitting the threshold requires minimal extra investment. The team-wide CRIT DMG buff makes this exceptional in any composition.
2
Duran, Dynasty of Running Wolves
Strong alternative specifically in follow-up attack teams. Stacks buffs each time an ally launches a follow-up attack, ultimately granting Aventurine a significant DMG bonus and providing the team with CRIT DMG on the 5th stack. Pairs excellently with Feixiao or Dr. Ratio.
Best Teams for Aventurine
Aventurine is the top sustain choice for follow-up attack teams and works as premium shielding in virtually any composition. His Unnerved debuff (+9% CRIT DMG) and Blind Bet follow-up add offensive value beyond pure sustain.
01 · FUA Premium
Best-in-slot follow-up composition
Feixiao benefits from every follow-up attack on field, and Aventurine's Blind Bet follow-ups count. Robin boosts everyone's CRIT DMG and provides action advance. Topaz amplifies follow-up DMG taken and provides consistent Numby attacks. Aventurine shields freely, stacking Duran Dynasty buffs each round.
02 · Acheron Nihility
Premier sustain for Acheron teams
Aventurine is the preferred sustain for Acheron since he provides shields without requiring healing actions. His Ultimate applies Unnerved, which counts as a debuff to help charge Acheron's Slashed Dream. Jiaoqiu and Black Swan fill both Nihility slots for the full 160% Abyss multiplier.
03 · Dr. Ratio FUA
Solid follow-up attack variant
04 · F2P · Budget
All accessible characters
Pela is a free 4-star who provides DEF shred and Nihility qualification. Silver Wolf implants Lightning Weakness for consistent Toughness break and provides two Nihility units for Acheron's full Abyss bonus. Aventurine handles all sustain needs without healing actions.

Eidolons
E
1
Prisoner's Dilemma
Increases CRIT DMG by 20% for allies who have Fortified Wager. After Aventurine uses his Ultimate, provides all allies with a Fortified Wager shield equal to 100% of the Skill's shield effect, lasting for 3 turns. This essentially gives the team a free shield refresh on every Ultimate cast and meaningfully boosts team-wide damage output.
High Pull Value
E
2
Bounded Rationality
When using Basic ATK, reduces the target's All-Type RES by 12% for 3 turns. Converts his rarely-used Basic ATK into a meaningful team utility tool, particularly useful in situations where Skill Points are scarce and Basic ATK is the only available action.
Solid Upgrade
E
3
Droprate Maxing
Ultimate Lv. +2 (up to max Lv. 15) and Basic ATK Lv. +1 (up to max Lv. 10). The Ultimate level increase boosts the DEF-scaling damage on the main hit and the CRIT DMG bonus applied by Unnerved. A meaningful damage bump on one of his highest-scaling abilities.
Incremental
E
4
Unexpected Hanging Paradox
When triggering the Talent's follow-up attack, first increases Aventurine's DEF by 40% for 2 turns and additionally increases the Hits Per Action for his Talent's follow-up attack by 3 extra hits (from 7 to 10). The DEF buff during the follow-up substantially increases each hit's damage, and the extra hits compound that bonus further.
Strong Upgrade
E
5
Ambiguity Aversion
Skill Lv. +2 (up to max Lv. 15) and Talent Lv. +2 (up to max Lv. 15). Stronger shields from the Skill and stronger follow-up hits from the Talent. Both are core to his kit, so this provides meaningful incremental improvement across his two most-used abilities.
Incremental
E
6
Stag Hunt Game
For every ally who has a Shield, the DMG dealt by Aventurine increases by 50%, up to a maximum of 150%. Since all four members of the team will have Fortified Wager, this is effectively a permanent +150% DMG multiplier for Aventurine, transforming him from a sustain with incidental damage into a genuine secondary damage dealer.
Massive Upgrade
Major Traces
Leverage
Ascension 2
For every 100 DEF above 1600, Aventurine's CRIT Rate increases by 2%, up to a maximum bonus of +48%. This trace is the core reason to stack DEF. At 4000 DEF he reaches close to the cap, meaning DEF% rolls provide both better shields and near-free CRIT Rate with no additional investment.
Hot Hand
Ascension 4
When battle starts, grants all allies a Fortified Wager shield whose Shield effect is equal to 100% of the one provided by the Skill, lasting for 3 turns. The entire party enters every fight fully shielded without Aventurine needing to spend his first action on the Skill, enabling a more aggressive opening rotation.
Bingo!
Ascension 6
After an ally with Fortified Wager launches a follow-up attack, Aventurine accumulates 1 Blind Bet (up to 3 times per turn). After Aventurine's Talent follow-up triggers, provides all allies with an additional Fortified Wager shield equal to 7.2% of DEF + 96, and gives the ally with the lowest shield an extra identical shield.

Frequently Asked Questions
No. Aventurine is fully functional with Moment of Victory, which is one of the strongest Preservation cones in the game. Inherently Unjust Destiny is a meaningful upgrade in shield strength and overall damage, but Moment of Victory is so strong that the gap is smaller than for most character signatures. Run either one confidently in all endgame content.
Aim for at least 4000 DEF. At 4000 DEF, the Leverage trace provides close to its maximum +48% CRIT Rate bonus (calculated as (4000 - 1600) / 100 * 2% = 48%). Higher DEF above 4000 still improves shield values but yields diminishing CRIT Rate gains. Prioritize DEF% on Body, Feet, Sphere, and Rope main stats to reach this threshold.
Blind Bet is Aventurine's passive energy system. He gains 1 point when any ally with Fortified Wager is attacked, 1 point when he himself is attacked, and up to 3 points per turn when allies with shields use follow-up attacks (from the Bingo! trace). His Ultimate randomly grants 1 to 7 additional points. At 7 points, he consumes them and instantly launches a 7-hit follow-up attack. The cap is 10 points, so excess points carry over toward the next follow-up.
Broken Keel is the default best-in-slot because the team-wide +10% CRIT DMG bonus is unconditional once Aventurine hits 30% Effect RES, which his Talent almost guarantees. Duran, Dynasty of Running Wolves can outperform Broken Keel in dedicated follow-up attack teams (Feixiao, Dr. Ratio, Topaz) where Duran's stacks charge quickly. Outside of FUA-heavy compositions, Broken Keel wins reliably.
Yes. Aventurine at E0 is one of the top two or three sustain units in the game. His shields are strong enough, his Blind Bet follow-up deals meaningful damage, and his Unnerved debuff provides team utility. E1 is the most impactful eidolon, adding 20% CRIT DMG for all shielded allies and a free shield refresh after Ultimate. E4 and E6 are significant damage upgrades for players looking to push his ceiling. All endgame content is fully clearable at E0.
Aim for at least 134 Speed so Aventurine can act twice per cycle, ensuring shield uptime and more Skill Point generation. If you sacrifice Feet main stat DEF% for a Speed boot, make sure to compensate with DEF% substats elsewhere so you still reach 4000 DEF. In most builds, DEF% Feet are recommended first, then Speed is pursued through substats. Once you hit 4000 DEF and 134 Speed, shift focus to CRIT DMG for maximum follow-up output.
