Relic/Sets

In the dynamic world of Honkai: Star Rail, optimizing your characters goes beyond leveling and Light Cones. The Relic system is where you truly fine-tune your team's power, granting crucial stat boosts and powerful set bonuses that can define a character's role and effectiveness. Whether you're building a hyper-carry, a durable support, or a specialized debuffer, understanding these sets is key to conquering the game's toughest challenges. This guide breaks down the unique bonuses of available Cavern Relic sets, helping you plan your farming strategy for the characters you love.

Understanding Relic Sets: The Basics

Before diving into specific sets, remember the core principle: Relics come in pairs. Equipping two pieces from the same set activates a 2-Piece bonus, which is often a straightforward stat increase. The real game-changer is the 4-Piece bonus, which provides a more complex and powerful effect, usually tied to specific combat actions. Your goal is to match these bonuses to a character's innate kit and intended team role.

Elemental & Offensive Sets

These sets directly amplify a character's damage output, often specializing in a particular element or attack type.

As Navigator I See Sees It

• 2-Piece Bonus: Increases ATK by 12%.
• 4-Piece Bonus: Upon entering combat or using a Skill, the DMG dealt by the wearer's Skill and Ultimate increases by 18%, stacking up to 3 times. At the start of the wearer's turn or after using Ultimate, one stack is removed.
  • Analysis: A powerful set for characters who frequently use their Skill and have a burst-damage Ultimate. It rewards a cycle of Skill usage to build stacks, followed by a powerful Ultimate, but you must manage the stack decay.

Band of Sizzling Thunder

• 2-Piece Bonus: Increases Lightning DMG by 10%.
• 4-Piece Bonus: When the wearer uses their Skill, increases their ATK by 20% for 1 turn.
  • Analysis: A premier set for dedicated Lightning DPS characters. The 4-Piece bonus offers a significant, consistent ATK boost every time they use their Skill, which is usually their main source of damage.

Champion of Streetwise Boxing

• 2-Piece Bonus: Increases Physical DMG by 10%.
• 4-Piece Bonus: After the wearer attacks or is hit, their ATK increases by 5% for the rest of the battle, stacking up to 5 times.
  • Analysis: This set turns any Physical DPS into a scaling threat. The permanent ATK increase from both dealing and receiving hits makes the wearer stronger as the fight goes on, perfect for longer encounters.

Eagle of Twilight Line

• 2-Piece Bonus: Increases Wind DMG by 10%.
• 4-Piece Bonus: After the wearer uses their Ultimate, their action is Advanced Forward by 25%.
  • Analysis: The go-to set for Wind DPS characters who rely on their Ultimate for major damage or debuffs. The action advance mechanic can help maintain momentum and allows for more frequent Ultimate deployments.

Ever-Glorious Magical Girl

• 2-Piece Bonus: Increases CRIT DMG by 16%.
• 4-Piece Bonus: The Elation DMG dealt by the wearer and their memosprites ignores 10% of targets' DEF. For every 5 accumulated Punchline allies gain, the Elation DMG dealt additionally ignores 1% of targets' DEF, stacking up to 10 times.
  • Analysis: A highly specialized set for characters who deal Elation DMG and utilize memosprites (like summons). It provides both immediate and scaling DEF ignore, empowering follow-up attack-centric teams.

Support & Utility Sets

These sets provide bonuses that benefit the entire team, enhance survivability, or enable unique strategic actions.

Divine-Querying Master Smith

• 2-Piece Bonus: Increases Max HP by 12%.
• 4-Piece Bonus: Increases the wearer's CRIT DMG dealt to enemy targets in the DEF reduction state by 28%. After the wearer inflicts the DEF reduction state on an enemy, all allies gain "Comburent" for 2 turns, increasing their DMG dealt by 15%. This effect can be triggered again after the wearer uses an attack.
  • Analysis: A fantastic hybrid set for a support who can inflict DEF reduction (like a Nihility character). It turns the wearer into a potent damage amplifier, boosting both their own CRIT DMG against debuffed foes and granting a team-wide damage buff.

Diviner of Distant Reach

• 2-Piece Bonus: Increases SPD by 6%.
• 4-Piece Bonus: Before entering combat, if the wearer's SPD is ≥120/≥160, increases their CRIT Rate by 10%/18%. When the wearer uses an Elation Skill for the first time in each battle, enhances all allies' Elation by 10%.
  • Analysis: This set bridges the gap between support and sub-DPS. The SPD and conditional CRIT Rate help the wearer act faster and deal more reliable damage, while the one-time team Elation boost benefits all follow-up attack allies.

How to Choose the Right Set

Selecting a Relic set isn't just about matching an element. Consider these factors:

1. Character's Primary Role: Is your character a main DPS, a sub-DPS, a healer, or a debuffer? A healer may prefer Max HP sets, while a debuffer wants sets that enhance their supportive effects.
2. Skill Rotation: Analyze how the character plays. Do they use their Skill every turn? Sets like "Band of Sizzling Thunder" reward this. Are they an Ultimate-focused character? Look at "Eagle of Twilight Line."
3. Team Synergy: Some sets, like "Divine-Querying Master Smith," have bonuses that activate based on debuffs your team applies or that provide buffs to allies. Choose sets that complement your entire team's strategy.
4. Farming Efficiency: Since you get Relics from Caverns of Corrosion, it's often efficient to farm a domain that drops sets for multiple characters you're building.

Summary & Key Takeaways

Building the perfect Relic set in Honkai: Star Rail is a blend of strategy, patience, and a bit of luck. Remember these core points:

• Match the Mechanic: Always align the 4-Piece bonus with the character's in-game actions (Skill, Ultimate, follow-up attacks, etc.).
• Element First, Then Set: For DPS characters, start by finding a set that boosts their specific element (Lightning, Wind, Physical, etc.).
• Supports Amplify: Don't neglect your support characters. Sets that boost team damage or enable strategic actions can be just as impactful as a DPS set.
• Check the Conditions: Pay close attention to the activation conditions. Some bonuses are permanent, while others require specific turns or actions to trigger and maintain.
• Adapt and Experiment: The "best" set can vary based on the specific characters and team compositions you use. Be ready to adapt your plan as you acquire new characters and tackle different challenges.
