Relic

Relics are the backbone of character progression in Honkai: Star Rail, offering the stat boosts and set bonuses needed to tackle tougher content. Think of them as your character’s specialized gear—phantasmal equipment formed from stardust and data. Understanding how to obtain, upgrade, and optimize them is essential for any Trailblazer looking to strengthen their team. This guide will break down the fundamentals of the Relic system based on available information.

What Are Relics?

In the world of Honkai: Star Rail, Relics are equippable items that provide characters with additional statistics, enhancing their performance in combat. They are described as phantasmal equipment that converges in the mysterious Fragmentum. Each Relic can be upgraded using special EXP materials to increase its base stats, making your characters stronger over time.

A key feature of Relics is the set bonus system. When a character equips multiple Relics from the same set, they unlock powerful additional effects. This encourages players to think about combinations rather than just individual pieces.

The Two Types of Relics

The Relic system is divided into two distinct categories, each with its own acquisition method and equipment slots.

Cavern Relics

Cavern Relics are the primary set of equipment players will encounter. They become accessible after completing the Trailblaze Mission "Ones Fallen Into the Abyss" in the chapter "In the Withering Wintry Night."

You can equip up to four Cavern Relics on a single character, occupying these specific slots:

Head
Hands
Body
Feet

Importantly, the main stat for the Head slot is always HP, and the main stat for the Hands slot is always ATK. The Body and Feet slots, however, can have a variety of other main stats, allowing for more customization depending on a character's needs.

Planar Ornaments

Planar Ornaments represent the second category of Relics. They are unlocked during a separate Trailblaze Mission, though the source material cuts off before specifying the exact mission name. Further details about their specific slots, acquisition methods, and set bonuses would require checking additional in-game information or official guides.

Understanding Relic Stats

Every Relic has stats that define its power. The two key components are the Main Stat and Subsidiary Stats (often called sub-stats).

Main Stat: This is the primary stat bonus provided by the Relic. As mentioned, it is determined by the Relic's type (e.g., Head Relics always have HP). Upgrading a Relic increases the value of its main stat.
Subsidiary Stats: Depending on a Relic's rarity, it can have up to four additional random stats. These sub-stats are where much of the customization and farming depth comes from, as they can significantly boost a character's strengths. The pool of possible sub-stats varies, and players often seek specific combinations for their builds.

How to Obtain and Upgrade Relics

Acquiring Relics is a core part of the gameplay loop. The sources indicate a couple of primary methods:

Caverns of Corrosion: This is highlighted as the main and most efficient way to farm for Cavern Relics. These challenges are designed specifically for Relic acquisition.
Exploration and Trailblaze Level Rewards: You can also find Relics as rewards while exploring the game's worlds or by reaching certain Trailblaze Levels.

To make your Relics stronger, you must upgrade them. This is done using EXP materials. Each upgrade level increases the Relic's main stat and, at certain thresholds, can also unlock or improve its sub-stats.
