Best Relics for Aventurine

Select the most effective Relics for Aventurine in Honkai: Star Rail. Optimize his defenses and offensive potential with these recommended sets.

Aventurine's relic build in 2026 should focus on maximizing his DEF stat to enhance his shielding capabilities and personal damage, while also providing crucial team utility. The undisputed best-in-slot Relic set for Aventurine is the Knight of Purity Palace set. This 4-piece set provides a significant 15% DEF boost, which is the cornerstone of Aventurine's kit. Furthermore, it increases the damage of his Ultimate by 10%, a valuable bonus that synergizes with his offensive contributions. The 2-piece bonus of this set also grants a 10% DEF increase, ensuring that every piece contributes to his primary scaling stat.

An excellent alternative for Aventurine, especially if the Knight of Purity Palace set is proving difficult to farm, is a 2-piece Knight of Purity Palace combined with a 2-piece Defender of the Past set. The latter provides a 10% DEF boost, making it a direct upgrade to his defensive capabilities. This combination allows for a strong DEF focus while still offering a substantial defensive bonus.

For the main stats on Aventurine's Relics, prioritize DEF% Boots on his Feet. This is non-negotiable for maximizing his shielding power. His Body piece should also be DEF%. While other stats might seem appealing, the direct DEF increase is paramount for his role. For his Planar Sphere, DEF% is again the optimal choice, further amplifying his defensive scaling. However, if playing in a team where his Ultimate can be reliably triggered often, and his personal damage is a higher priority, a Quantum DMG Bonus% sphere could be considered, but this is a niche build.

His Link Rope should be Energy Regeneration Rate. This is crucial for ensuring Aventurine can consistently use his Ultimate, Unending Starlight, which provides a substantial shield to all allies and applies a debuff to enemies. A higher Energy Regeneration Rate means more frequent shielding and more consistent application of his team-wide buffs. A DEF% Link Rope can be a fallback if Energy Regeneration is not a concern or if You is struggling to reach the required DEF threshold.

When it comes to substats, the priority is clear: DEF%, followed by HP% for added survivability. Effect RES is also a valuable substat to prevent him from being debuffed and losing his defensive capabilities. Crit Rate and Crit Damage are tertiary stats that can contribute to his personal damage, but they should not come at the expense of DEF or HP.
