Aventurine’s Kit and Eidolons
Aventurine’s kit revolves around his unique energy mechanic, Blind Bet, and his powerful follow-up attacks.
You gain Blind Bets by using his Skill, which applies a shield to an ally and adds 1 Blind Bet to your stack. When Aventurine has collected 6 Blind Bets, his ultimate is released automatically. His Ultimate deals Imaginary DMG and buffs the Crit Rate of all allies for 2 turns.
Once his allies are shielded up, any time they’re hit, Aventurine will release a follow-up attack in retaliation.

Best Light Cones for Aventurine
Light Cones that buff Aventurine’s shield and follow-up attacks are exactly what he’s looking for.
BEST – Inherently Unjust Destiny
Inherently Unjust Destiny synergizes perfectly with Aventurine’s full kit. It grants him increased Crit DMG whenever he grants a shield to an ally and also provides a chance to increase the DMG received by targets who are hit by his follow-up attack.
Alternative – Moment of Victory
Moment of Victory works a bit like a permanent “Taunt” effect, increasing the chances its wearer will be attacked by enemies. This makes it a good pair with Aventurine’s shield mechanic, since you can draw attacks to Aventurine, who will almost always have his shield up. It doesn’t synergize with any of his other mechanics, though, and that one-dimensionality makes it a worse fit than Inherently Unjust Destiny.
Best Relics for Aventurine
BEST – Knight of Purity Palace
Knight of Purity Palace is far and away the best Relic Set for Aventurine because it makes his shields more effective. With the full set equipped, Aventurine gets an increase to the max DMG that can be absorbed by the shields he creates. This directly translates to more opportunities for follow-up attacks and more effective shields.
Main/Substats
- Body (Crit DMG or Crit Rate): Increasing Crit DMG and Crit Rate makes Aventurine’s follow-up attacks more effective.
- Feet (ATK% or Speed): Unlike some characters, hitting Speed breakpoints isn’t as crucial on Acheron. You want to give other characters turns between Acheron’s so you can apply debuffs and more easily time Crimson Knot stacks and your Ultimate.
- Planar Sphere (Lightning DMG): Boost Acheron’s Ultimate by buffing up her Lightning DMG.
- Link Rope (ATK%): More is always better.
- You want a Crit Rate between 70–80% with a Crit DMG of 160–200%.
How to Play Aventurine
Aventurine’s kit revolves around stacking his Talent-based shield and building up blind bets to trigger his Ultimate. Here’s the optimal rotation to get the most out of this character:
- Use Skill
- Apply a shield to the ally with the lowest HP%
- Gain 1 Blind Bet
- Basic ATK or Skill
- Use Skill again if shield uptime or energy is a concern. This will add another Blind Bet stack and refresh your shields.
- Otherwise, use Basic ATK to deal DMG and save skill points.
- Repeat steps 1 and 2 until you have 6 Blind Bets
- Unleash your Ultimate
- Aventurine’s Ultimate activates automatically when he accumulates 6 Blind Bets
- Deals Imaginary DMG and gives allies a Crit DMG buff for 2 turns
- Resets Blind Bets to 0
Aventurine’s Talent lets him perform follow-up attacks when shielded allies are attacked. So, to allow Aventurine to deal DMG as often as possible, you want to keep shields up on your allies.
