Aventurine is an Imaginary element character who follows the Path of Preservation. His kit revolves around providing shields, triggering follow-up attacks (FUA), and increasing the Crit DMG enemies receive.
Best Cavern Relics
(2) Increases DEF by 15%.
(4) Increases the max DMG that can be absorbed by the Shield created by the wearer by 20%.
The Knight of Purity Palace relic set has long been the go-to choice for most Preservation characters—Fu Xuan being the notable exception. For Aventurine, this set significantly enhances his shielding capability, allowing his barriers to absorb more damage and provide stronger protection against enemy attacks.
Best Planar Ornaments
(2) Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.
Broken Keel stands out as Aventurine’s best Planar Ornament, since his Talent grants him 50% Effect RES upon deploying or maintaining his shield—allowing him to consistently trigger the set’s Crit DMG bonus.

info
Aventurine’s stat priority begins with reaching 4,000 DEF to unlock the full 48% Base Crit Rate from his Talent. Any DEF beyond that further enhances his shield’s absorption. Equipping SPD boots and reaching at least 135 SPD is also recommended to ensure more frequent turns. Once his DEF and SPD are in a good place, you can shift focus to boosting Crit Rate and Crit DMG to improve the damage of his follow-up attacks and Ultimate. Aventurine doesn’t require Effect RES from substats, as his Talent grants 50% when deploying or maintaining a shield. This also enables consistent activation of the Broken Keel’s Crit DMG buff, enhancing overall team damage.

Verdict
Increases the wearer's DEF by 24~40% and Effect Hit Rate by 24~40%. Increases the chance for the wearer to be attacked by enemies. When the wearer is attacked, increase their DEF by an extra 24~40% until the end of the wearer's turn.Moment of Victory greatly boosts Aventurine’s DEF and shield strength, key to his kit. However, its Effect Hit Rate is less useful since his Unnerved debuff is guaranteed.

A New Round of Shuffling

For each turn, the wearer deals DoT that is equal to 40~80% of the wearer's DEF for 2 turn(s).The Trend of the Universal Market is a niche Light Cone primarily used by Aventurine in Acheron teams. Its effect inflicts Burn when the wearer is hit, and this debuff counts as one stack of Crimson Knot for Acheron. Do note however that its effects doesn't provide DEF, making Aventurine's shield softer than other Light Cone optio
