砂金 Build Guide — Best Relics, Light Cones & Teams | GameBeliever

砂金 Build Overview

Aventurine (砂金) is a 5-star Imaginary character who walks the Path of Preservation. As a tank, his primary role is to protect the team, but unlike traditional Preservation units that offer raw HP scaling, Aventurine’s kit revolves around generating shields that scale with his CRIT Rate and DEF. His unique mechanic allows him to convert offensive stats into defensive utility, making him a hybrid tank who thrives in teams that can provide a steady stream of positive effects (buffs, debuffs, follow-up attacks).

The core philosophy of an optimal 砂金 build is to stack as much CRIT Rate as possible while maintaining high DEF. This maximizes the potency of his shields, which are granted to all allies when he accumulates a certain number of follow-up attack stacks. His Imaginary element also allows him to contribute minor break and imprisonment utility. This guide will detail how to build him to become an unbreakable shield for your team while dishing out respectable personal damage.

Best Relics for 砂金

Best 4pc Set

The undisputed best-in-slot 4-piece set for 砂金 is The Wondrous Banyan.

• Why: The 2-piece bonus grants a 15% DEF boost, which directly scales his shield strength and personal damage. The 4-piece bonus is where the true power lies: when a shielded ally is attacked, 砂金 gains a stack of “Dreamy,” up to 4 stacks. At maximum stacks, his follow-up attack deals 25% increased CRIT DMG. Since his core gameplay loop is built around generating follow-up attacks to refresh team shields, this set is universally synergistic and provides a massive offensive boost without sacrificing defense.

Alternative Sets

If you are farming for multiple characters or lack a good Wondrous Banyan 4-piece, you can use a 2pc + 2pc combination:

• The Wondrous Banyan (2pc) + The Wind-Soaring Valorous (2pc): This combination provides +15% DEF and +8% CRIT Rate. It’s an excellent stepping stone that directly boosts his two most important stats.
• The Wondrous Banyan (2pc) + Messenger Traversing Hackerspace (2pc): Use this if your team is severely lacking SPD. The +6% SPD from Hackerspace can help 砂金 reach important breakpoints to generate his stacks faster.
• The Guard of Wuthering Snow (2pc) + The Wondrous Banyan (2pc): A purely defensive option. The 15% DEF and damage reduction/Healing when HP is low can make him incredibly durable, though it sacrifices personal damage.

Best Planar Ornaments

• Best-in-Slot: Belobog of the Architects. The 2-piece set grants 15% DEF and, if his DEF is 1500 or higher, an additional 15% DEF. This is the most straightforward and powerful set to maximize his shield and damage scaling.
• Alternative Option: Fleet of the Ageless. If you find yourself unable to hit the 1500 DEF breakpoint or want more team utility, this set provides 8% Max HP and, when his SPD is 120 or higher, an 8% ATK boost to all allies. This is less personal damage but aids the team’s overall output.
• Situational Option: Penacony, Land of the Dreams. If you are running him in a dual Imaginary carry team (e.g., with Dr. Ratio), this set can provide an 18% DMG boost to Imaginary characters and an extra 5% Energy Regeneration Rate for the wearer.

Recommended Main Stats

• Body: CRIT Rate is the non-negotiable priority. Your goal is to stack as much as possible to fuel his shield mechanic and damage.
• Feet: SPD is the standard choice to help him act more frequently, generate energy, and build his follow-up stacks. DEF% is an alternative if you have godly SPD substats elsewhere and can hit 134+ SPD from substats alone.
• Planar Sphere: DEF% for maximum shield strength and damage.
• Link Rope: Energy Regeneration Rate (ERR) is highly recommended to ensure his Ultimate is available often. His Ultimate provides significant DMG and generates follow-up stacks. DEF% is the alternative for a more personal damage-focused build.

Substats Priority

1. CRIT Rate (to reach the breakpoints listed below)
2. DEF% (to increase shield and damage)
3. SPD (to reach key breakpoints)
4. CRIT DMG (to capitalize on his multipliers)
5. Break Effect (a nice luxury stat for his Imaginary Breaks)

Minimum Breakpoint: Your absolute first goal is to get 砂金’s DEF to 1500 to activate the Belobog of the Architects bonus. Beyond that, stack CRIT Rate.

Best Light Cones for 砂金

5★ Light Cones

• Signature Light Cone: Incessant Rain. This is tailor-made for him. It provides a massive 32% DEF boost and a 20% CRIT DMG increase to all allies when the wearer inflicts a debuff. Since 砂金’s Ultimate inflicts “Blind Bet,” this is almost always active, providing unparalleled team utility.
• Other 5★ Options: Moment of Victory. An excellent alternative, offering 32% DEF and increasing the effect hit rate of the wearer’s Ultimate. While the aggro increase is less relevant for a tank, the raw DEF stat is fantastic.
• Texture of Memory. A strong defensive 5★ option. Grants a 24% Max HP increase and creates a damage-reducing shield when the wearer’s turn begins. This makes him incredibly hard to kill but provides no offensive or team benefits.

4★ Light Cones

• Best 4★ Choices: Day One of My New Life. This is the king of 4-star Preservation Light Cones. It provides a 16% DEF boost and, when an ally is attacked, increases the DEF of all allies by 16% for 2 turns. The team-wide DEF buff is incredible and scales well into the late game.
• Event/Alternative Options: This Is Me! From the Nameless Honor battle pass. It gives 16% DEF and increases the wearer’s DMG by 20% for 2 turns after using their Ultimate. A great personal damage option if you have the pass.
• Landau’s Choice. A niche but effective option for pure survivability. The wearer becomes the target of enemy attacks and takes 24% less DMG. This forces enemies to attack your tank, protecting squishier teammates.

F2P Light Cones

• Budget Choice: Trend of the Universal Market. Obtained from the Simulated Universe World Store. Provides 16% DEF and, when the wearer is attacked, has a high chance to burn the attacker. This adds a nice bit of damage and minor Break effect.
• Other F2P Option: We Will Meet Again. From the Herta Store. Provides 16% DEF and increases the wearer’s DMG dealt by 20% after using a Basic ATK or Skill. Easy to superimpose and a solid stat stick.

Light Cone Comparison

Light Cone	Rarity	Key Stat	Notable Passive	Best For
Incessant Rain	5★	+32% DEF	+20% Allied CRIT DMG on debuff infliction	Ultimate team support, BiS
Moment of Victory	5★	+32% DEF	+24% EHR on Ultimate	High personal DEF, F2P 5★ option
Day One of My New Life	4★	+16% DEF	+16% Allied DEF on ally being hit	Best 4★, team support
This Is Me!	4★	+16% DEF	+20% Self DMG after Ultimate	Personal damage focus
Trend of the Universal Market	3★	+16% DEF	Burn on being hit	F2P, adds DoT/Break

Stats Breakpoints & Targets

• CRIT Rate Target: Aim for 70% minimum. Since his shields scale directly with CRIT Rate, this is his most important stat. Going higher to 80-90% is excellent if substats allow.
• CRIT DMG Target: With 70% CRIT Rate, aim for 140% as a soft goal. He has decent multipliers, so this will contribute meaningfully to his personal damage.
• SPD Breakpoints: The most important breakpoint is 134 SPD, which allows him to act twice in the first cycle of Memory of Chaos. If using Fleet of the Ageless, you need 120 SPD. 143 SPD is the next major breakpoint for three actions in the first two cycles.
• Other Important Stats:
  • DEF: 2500-3000 is a solid endgame target. This ensures his shields are robust. His DEF must be at least 1500 to activate Belobog.
  • Effect Hit Rate (EHR): Only needed if you want to ensure his Ultimate’s imprisonment lands consistently. Around 40-50% is sufficient against most enemies.

Best Team Compositions

砂金 excels in teams that can provide consistent buffs, debuffs, or follow-up attacks to fuel his stack generation.

Premium Team

• Team: Aventurine, Dr. Ratio, Silver Wolf, Ruan Mei
• Why It Works: This is a premier Single-Target focused team. Silver Wolf provides consistent debuffs, activating Dr. Ratio’s and Aventurine’s bonuses (like Incessant Rain). Ruan Mei provides massive DMG buffs and Weakness Break efficiency. Dr. Ratio and Aventurine form a devastating follow-up attack duo. Aventurine’s shields keep the team alive while contributing significant Imaginary Break and personal damage.

F2P Team

• Team: Aventurine, March 7th, Dan Heng • Imbibitor Lunae, Asta
• Why It Works: A hypercarry setup. Dan Heng • Imbibitor Lunae is the primary damage dealer. March 7th provides additional shields and taunt, working synergistically with Aventurine’s Preservation path. Asta provides crucial ATK and SPD buffs to the entire team. Aventurine’s job is to keep everyone alive and contribute Imaginary Breaks and chips of damage.

Alternative Teams

• Follow-Up Attack Synergy: Aventurine, Topaz & Numby, Dr. Ratio, Ruan Mei. All units utilize follow-up attacks, creating a constant barrage that generates Aventurine’s stacks instantly.
• Imaginary Break: Aventurine, Welt, Silver Wolf, Himeko. This team focuses on breaking multiple weaknesses with Imaginary, using Welt and Aventurine to imprison and delay enemies, controlling the battlefield completely.

Gameplay Tips & Rotation

• Skill Rotation: Your rotation is straightforward. Use your Basic ATK to generate Skill Points when your team is fully shielded and healthy. Use your Skill to grant a fresh shield to the entire team when it’s depleted or about to expire. Always use your Ultimate when available, as it generates follow-up stacks and deals AoE Imaginary DMG.
• Key Combos: The key is timing. After an ally with a shield is attacked, Aventurine’s follow-up attack is triggered. This is automatic, so your gameplay focus is on using his Skill preemptively to ensure shields are up before the enemy attacks. Against bosses with AoE attacks, this can trigger his follow-up multiple times in one turn.
• Common Mistakes to Avoid:
  1. Ignoring DEF: Building pure CRIT without enough DEF will result in paper-thin shields.
  2. Hoarding his Skill: Don’t wait until shields break. Apply it proactively before powerful enemy attacks or AoEs.
  3. Forgetting his Ult’s Debuff: His Ultimate inflicts “Blind Bet,” a debuff. This is crucial for activating certain Light Cone effects (like Incessant Rain) and ally abilities (like Dr. Ratio’s).

Investment Priority

• E0 Viable? Absolutely. Aventurine is completely functional and top-tier at E0. His core shield-generating mechanic is inherent to his kit.
• Key Eidolons:
  • E1 (Crisis Rebate): A strong quality-of-life Eidolon. After using his Ultimate, all allies receive a shield equal to 100% of his DEF. This guarantees shield uptime.
  • E2 (High Stakes): When an ally with his shield inflicts a debuff, Aventurine gains 1 stack of Blind Bet. This dramatically increases his follow-up attack frequency in debuff-heavy teams.
  • E6 (All-In): When using his Ultimate, he gains 6 stacks of Blind Bet, guaranteeing an immediate follow-up attack and massive personal DMG. It’s a powerful but luxury damage-focused Eidolon.
• Light Cone Priority: Incessant Rain > Moment of Victory > Day One of My New Life. If you have a 5-star option, use it. If not, a superimposed Day One of My New Life is incredibly competitive and team-friendly.
