Basic Introduction

Aventurine is a a powerful Preservation character. He can grant all allies a shield by using his Skill. When an enemy attacks a shielded ally or an ally does a follow-up attack, he will charge his follow- up that will also stack the shield effect up to 200% of the Skill’s shield amount. It is important to note that all Aventurine’s attack scales from his DEF.

Trace Priority

Aventurine relies mostly on his Skill and Talent to maximize the amount of the shield generated. To maximize his potential, focus on upgrading his Skill and Talent with his Ultimate. His Basic ATK is the least important trace since the scaling does not have much of a difference. In short, his trace priority is Skill > Talent > Ultimate > Basic ATK.
