The best Aventurine build in Honkai: Star Rail (Version 4.6) is Inherently Unjust Destiny with Self-Enshrouded Recluse. Updated November 5, 2026
Stack DEF as a priority until you hit 4000, while doing so aim for the most appropriate Speed breakpoint for your teams. After reaching 4k DEF, stack CRIT DMG and CRIT Rate aiming for a 1:2 CRIT Ratio in-game (Aventurine only gains his CRIT Boost in combat). Alternatively, extra DEF% can be stacked for bigger shields.

Increases CRIT DMG by 20% for ally targets with Fortified Wager. After using the Ultimate, provides all allies with a Fortified Wager shield, whose Shield Effect is equal to 100% of the one provided by the Skill, lasting for 3 turn(s).
When using the Basic ATK, reduces the target's All-Type RES by 12% for 3 turn(s).
When triggering his Talent's Follow-Up ATK, first increases Aventurine's DEF by 40% for 2 turn(s), and additionally increases the Hits Per Action for his talent's Follow-Up ATK by 3.
For every teammate that holds a Shield, the DMG dealt by Aventurine increases by 50%, up to a maximum of 150%.
Acheron charges her Ultimate off debuffs other characters apply, so the team runs two more Nihility units and a sustain that never needs a Skill Point.
Feixiao converts ally attacks into her own follow-ups, so the other three slots are a follow-up partner, a Harmony unit that advances her, and a sustain.
Gilgamesh gains a stacking buff every time a teammate uses an Ultimate, and shares a joint follow-up with Saber, so the team is built around Ultimate frequency.
Rin turns Skill Point traffic into CRIT DMG for whoever spent it, and her joint follow-up needs Archer on the field, so the last two slots are picked for Skill Point economy.
Elation runs on Punchline the whole team feeds, so a second Elation character is worth more here than a stronger buff from another Path.
Ashveil marks one enemy as the Bait and follows up whenever an ally hits it, which makes a second follow-up character worth a slot on its own.
Honkai: Star Rail 5★ Imaginary Preservation Support
Inherently Unjust Destiny tops the light cone ranking for Aventurine at S1, ahead of Journey, Forever Peaceful, Moment of Victory and Day One of My New Life. That order is prydwen.gg's, measured in play and rephrased here; every row of it sits under Light cones below.
Run Self-Enshrouded Recluse on Aventurine, with Knight of Purity Palace and Pioneer Diver of Dead Waters behind it. The planar ornament is Broken Keel. Main stats are DEF% = CRIT DMG body, Speed >= DEF% feet, DEF% = Imaginary DMG sphere, DEF% rope. Roll substats in the order DEF% (aim for 4k) >= SPD > CRIT DMG > CRIT Rate > Effect RES.
Trace priority is Skill > Talent > Ultimate > Basic. The Ultimate costs 110 energy, which is what an Energy Regeneration Rate target has to clear.
Aventurine plays Sustain in the Acheron team, alongside Acheron, Jiaoqiu and Pela.
