What main stat to run, by role

Getting the main stat on the right slot is the baseline — substats aimed the right direction decide your real power. The table below is a default framework by role, useful for a quick lookup before you know a specific character's kit.

	Body	Feet	Planar Sphere	Link Rope	Sub-stat priority
Main DPS	CRIT Rate or CRIT DMG	ATK% or SPD	the character's own Elemental DMG Boost	ATK% (or Break Effect for a break-focused kit)	CRIT comes first — aim for roughly a 1:2 ratio of CRIT Rate to CRIT DMG — then ATK%, then SPD.
Healer	HP% or Outgoing Healing Boost	HP%	HP%	Energy Regeneration Rate or HP%	HP% first, then SPD — healing output scales off the target's Max HP.
Tank / Shielder	DEF% or Effect Hit Rate	DEF% or SPD	DEF%	DEF% or Energy Regeneration Rate	DEF% first, then Effect Hit Rate, then SPD.
Support	No safe default — depends on the character's kit, check that character's page	SPD, almost always correct	No safe default — depends on the character's kit, check that character's page	Energy Regeneration Rate	SPD first; add Effect Hit Rate if the character applies debuffs.

This is a default framework, not a hard rule. Some characters break from it because of their own kit — for example a support that needs CRIT DMG or Break Effect instead of Energy Regeneration Rate. Always check that character's page before locking in a set.

Basic rules you need before picking Relics

Head always rolls flat HP, Hands always roll flat ATK — no need to check the main stat on these two, just look at the substats.
Only Feet can roll SPD as a main stat; only the Link Rope can roll Energy Regeneration Rate as a main stat.
A substat never duplicates that piece's own main stat, and the four substats never duplicate each other.
Each piece caps at 4 substats. Every +3 upgrade grants one roll — either unlocking a new substat line or boosting an existing one at random.
Enhancement cap by rarity: 2-star +6, 3-star +9, 4-star +12, 5-star +15. Starting substat count: 3-star 1–2 lines, 4-star 2–3 lines, 5-star 3–4 lines.
The main stat is NOT random — at the level cap it's always the exact same fixed number. Only substats roll randomly.
Quick filter trick: enhance to +9 and you already see enough substat quality to decide keep-or-salvage — don't burn all your resources to +15 before judging.

Should you keep or salvage this piece?

Wrong main stat for the slot (e.g. an HP% Sphere on a Lightning DPS) → salvage it right away, don't get attached.
Right main stat but the 4 substats don't have even one line of CRIT Rate / CRIT DMG / SPD (for a DPS role) → low value, salvage first.
Right main stat plus at least 2 substats you actually need from the start → enhance to +9 and reassess — this piece is worth investing in.

Where can you get Relics?

Cavern of Corrosion — the main source of the 4 Cavern Relic pieces, with 6 difficulty tiers tied to your account's Equilibrium Level; the higher your Equilibrium Level, the thicker the 5-star drop rate.
Simulated Universe — source of the 2 Planar Ornament pieces, only unlocked from World 3 onward.
Divergent Universe — a second source for Planar Ornaments, separate from the Simulated Universe.
Operation Briefing — clearing these objectives also pays out Relics and related materials.
In-game shops — some vendors sell full 4-piece sets directly for in-game currency.
Treasure chests scattered across the main story maps.
Story quest rewards, plus milestone rewards for leveling up your Trailblaze Level.

Relics unlock during the Belobog story arc. To target the exact set and slot you need instead of farming blind, use the Omni-Synthesizer: it runs on Relic Remains, which you get by salvaging Relics you don't use. The machine unlocks from Equilibrium Level 3 onward.

Astropolis Media HeadquartersPlanar Sphere

Encased within the Planar Sphere lies Astropolis: the lofty headquarters of the Interastral Peace Entertainment. This media capital has churned out countless superstars, broadcasting entertainment products across the cosmos with industrial-grade precision.

Wherever credits flow, the IPC's media empire reaches.
Through Interastral Peace Entertainment's relentless innovation, human needs can now be quantified as emotional value per second, and a terminal device connected to the Interastral Peace Network. Trace the signal to its source, and you'll find Astropolis on Epsilon: the very heart of this universal media web.

This towering structure houses the offices of every department within the Interastral Peace Entertainment, jutting up from the surface like a needle pointing toward the sky. Armies of employees work around the clock, churning out movies, radio dramas, and variety shows. The user base they serve is so massive that every single project requires endless rounds of discussion and an industrialized workflow fine-tuned down to every last emotional beat.

The media moguls wanted to keep their department sizes right at the sweet spot on the profit margin curve, breaking down creativity into metrics they could measure and evaluate. One employee let slip that in the narrative database, you'd find tragedy plot points that could make even a Mourning Actor weep, and comedic formulas that'd have a Masked Fool doubled over with laughter. All of it is fed into an algorithm that's adjusted in real-time based on every micro-expression from the audience, ensuring maximum viewership ratings.

There's no denying it. Under the IPC's powerful operations, many cosmic superstars have risen to fame from this very place.
It's a dream factory for stardom, drawing wave after wave of young people chasing their dreams, giving their youth to their aspirations.
The tower's lights never go out. It's a clock hand forever pointing to midnight. Just as the first line of the Astropolis Employee Handbook reads: Humanity's hunger for entertainment knows no boundaries.

Astropolis Employee CredentialsLink Rope

Employee credentials from Astropolis, marked with rank and personnel information. Perhaps of everything above and beneath the sky, one of the very few things they share.

Gardens, beaches, shopping malls, sporting events... The IPC provides its employees with comfortable living spaces, using them as a showcase for humanity's ideal lifestyle. A model template for the "corporate dream."

After clocking out, head to the beach, go car racing, play volleyball, get on yachts, or attend concerts... There is bound to be a hobby for you to kill time and talk about.
Shopping is the best way to decompress from work. Luxury goods showcase the buyer's social standing, cheap entertainment is a shortcut to happiness. And don't forget: there's that sweet employee discount.
Given the chance, staff won't miss the opportunity to hawk their wares to the omnipresent cameras. A truly outstanding employee has already woven product promotion seamlessly into their life.

High above in the skyscraper where it pierces through the clouds, the tycoons dwell in floating structures, pondering the IPC's future.
Under the direction of Arita, head of the "Traditional Project Department," Astropolis has become neutral ground for the IPC's many departments. Divisions that normally clash gather here regularly to mend fences and smooth over their differences with civility.
It's a place where change takes root. Even the most trivial of decisions made up there can raise tidal waves down below.

Every so often, a lavish rain of bills cascades down from the rooftop above, landing on the heads of lucky employees. It's one of the rare chances to brush shoulders with the higher-ups.
You'll see it all flash through the eyes of ordinary workers: mania, excitement, resentment, boredom... The desire burning in their hearts, ignited like flames. That's the fuel that keeps Astropolis shining bright forever.

How to read this relic set page

Cavern Relics have 4 pieces: Head and Hand always carry fixed flat stats (HP and ATK), so only Body and Feet have a random main-stat you actually choose. The 2-piece effect unlocks with 2 out of 4 pieces from the same set; the 4-piece effect is stronger but needs all 4 and usually has its own trigger condition — read the exact text above before committing. Planar Ornaments only have 2 pieces (Planar Sphere + Link Rope) and only ever have one 2-piece effect, there is no 4-piece version.

The two types also differ in where you get them: Cavern Relics drop from the Cavern of Corrosion and cost Trailblaze Power per run; Planar Ornaments come from the Simulated Universe or Divergent Universe, which do NOT cost Trailblaze Power — you trade for them with items or completion rewards instead. A full loadout usually combines one 4-piece Cavern set (or two different Cavern sets at 2 pieces each) with one 2-piece Planar set — go 4-piece when that set gives a large, reliable damage buff, and mix 2+2 when you need to stack several smaller stats (e.g. ATK% from one set plus Elemental DMG% from another).

The "who should use this" list is pulled from cross-sourced build consensus and updates automatically as the meta shifts, it is not hand-picked. See the full set table on the Relics page, or check terms in the HSR Glossary.
