Honkai Star Rail Aventurine guide: Best build, materials, and trace priority

Aventurine is a super strong Preservation character.

Aventurine is the newest character to join Honkai Star Rail in version 2.1. As an Imaginary unit of the Path of Preservation, he fills a unique niche that makes him one of the most useful characters in the game.

Whether you’ve been saving your Stellar Jades for Aventurine or you decided to pull for him on a whim, you’ll be happy to have this fancy fellow on your roster. His materials are easy to farm for and he’s great at carrying your team through endgame content like Memory of Chaos and Pure Fiction.

Aventurine’s banner will kick off on Wednesday, April 17, 2024 after the Acheron banner ends. It will remain active until the release of Honkai Star Rail version 2.2 on Wednesday, May 8, 2024. That gives you a full three weeks to pull Aventurine before he disappears for an unknown period of time. A rerun will no doubt happen sometime in the future, but it’ll likely be a year or longer before he shows his face on a banner again.

Aventurine Kit and Playstyle

As a Preservation character, Aventurine provides support to your team by shielding them from incoming damage. He’s one of the best sustain units in the game even when compared to other top-tier Preservation tanks like Fu Xuan and Gepard.

His Skill, Cornerstone Deluxe, grants shields and boosts effect resistance to your entire team. When a shielded ally is struck, Aventurine gains stacks of Blind Bet, culminating in a powerful follow-up attack after reaching seven stacks. His Ultimate ability, Roulette Shark, gives him anywhere from one to seven stacks of Blind Bet at random while also attacking a target and inflicting them with Unnerved, which increases the CRIT Damage they take by 9%.

Blind Bet is Aventurine’s main gimmick. Shields, buffs, and debuffs are nice, but the follow-up attack from his Shot Loaded Right Talent triggers often and does a surprising amount of damage. It caps at 10 stacks too, so he’ll frequently have leftover stacks after spending seven to attack. Essentially, Aventurine helps your team resist crowd control debuffs (which is a godsend in high-level content), keeps them shielded, and frequently retaliates when your team gets hit. He has it all.

Best Relics and Planar Ornaments for Aventurine

Since Aventurine scales off DEF (and one of his Traces increases his CRIT Rate as his DEF increases), his best Relic set is Knight of Purity Palace. This increases his DEF by 15% and increases the maximum damage that his shields can absorb by 20%.

You could also use The Ashblazing Grand Duke with Aventurine if you have a decent set of that. It increases follow-up attack damage by 20% and increases Aventurine’s ATK by 6% every time his follow-up attack does damage. It’s a decent setup for a DPS-focused Aventurine build, but the buffs you’d get from increased DEF are much, much better.

For Planar Ornaments, look no further than Broken Keel for Aventurine. This set increases his Effect RES by 10% and boosts the entire team’s CRIT DMG by 10% when his Effect RES is at 30% or higher. You don’t even need to build Effect RES to achieve this since Aventurine’s Fortified Wager shield buffs Effect RES by 25% when applied, and he applies it to everyone on the team including himself.

Aventurine Stat Priority

There are only two stats that you want to build for Aventurine: DEF and CRIT DMG. Everything in his kit scales off DEF, so that’s self-explanatory. He doesn’t need any CRIT Rate stats since his Leverage Trace increases CRIT Rate by 2% for every 100 DEF exceeding 1600, which adds up. Because of that, you should prioritize CRIT DMG for Aventurine.

Here are the main stats you should be looking for with Aventurine’s relics.

  • Body: CRIT DMG or DEF%
  • Feet: DEF%
  • Sphere: DEF%
  • Rope: DEF%
  • Substat Priority: CRIT DMG, DEF%, SPD

DEF is the name of the game here and Aventurine excels when it’s as high as possible. Not only does it buff every part of his kit, but it also increases his overall CRIT Rate because of Leverage. Aventurine is so, so easy to build compared to other characters, especially since his best Relic set is remarkably common in Cavern of Corrosion.

Aventurine Eidolons

E1: Prisoner’s DilemmaIncreases Crit Damage for allies with Fortified Wager by 20%. After using Aventurine’s Ultimate, also provides a Fortified Wager Shield to the entire team, with the shield effect equaling 100% of that provided by Aventurine’s Skill, lasting for three turns.
E2: Bounded RationalityWhen using his basic attack, Aventurine reduces the target’s All-Type Resistance by 12% for three turns.
E3: Droprate MaxingIncreases the level of Aventurine’s Ultimate by two with a maximum upgrade level of 15, and increases the level of his Basic Attack by one, with a maximum upgrade level of 10.
E4: Unexpected Hanging ParadoxWhen triggering Aventurine’s talent’s follow-up attacks, his DEF first increases by 40% for two turns. The follow-up attack’s Hits Per Action triggered by his talent also increases by three.
E5: Ambiguity AversionIncreases the level of Aventurine’s Skill and Talent by two, with a maximum upgrade Level of 15.
E6: Stag Hunt GameWhen triggering Aventurine’s talent’s follow up attacks, his defense first increases by 40% for two turns. The follow-up attack’s Hits Per Action triggered by his talent also increases by three.

Aventurine’s Eidolons can significantly increase his combat capabilities if you have the Stellar Jades to spare. He’s strong enough at the base level, though, so you should probably just save your Stellar Jades for upcoming characters like Robin unless you’re willing to whale.
