2-piece or 4-piece?

Depends on the character: some only need the 2-piece bonus (mixing with another set), others need the full 4-piece to benefit from the main effect — check the two character lists above to see which group you fall into.

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.

Every piece & its lore

Official in-game name, description and story of each piece — tap to expand

Poet's Dill WreathHead

Before the Temple of Dusk in spring, the most outstanding of bards will receive a dill wreath bequeathed by Mnestia.

"Mnestia, we pray to you. For if the world had no song, there shall be no song-filled spring, and no forest will sprout blooms..."

After cleansing both hands by the stream, then scooping out chilled wine as an offering to the god, the bards gather before the temple, bickering over who would receive Mnestia's blessed wreath. The three sisters of Parthia, renowned for their poems of love, demonstrate their song first. They are followed by an old man, Lupes, the poet with myriad mesmerizing metaphors. Lyrics of honeyed elegance do not move the goddess, the wine cup before them unmoving.

Until a wandering poet plucks the seven-stringed lyre in her hands, playing a tale written on ancient papyrus. Sand and winds from a millennia ago sweep across, and the story starts thus — In an age when many cities still existed in the world, a city was attacked by an evil dragon.

"Lament for my homeland...
A monster dwells in its palatial hall, noble heirs becoming vile scoundrels,
All because of that giant dragon that breached the high tower,
Corrupting my ruler, devouring my kingdom's princess..."

The wine is imbibed fully by the goddess, and the wandering poet becomes the owner of their wreath.

Poet's Gilded BraceletHands

A bracelet crafted from favored metal. The evil dragon in the story was once fettered in shackles made from this metal.

"People dug up gold from Georios' body, the first fearsome metal of its kind. And thus deceit and war were born."

The origin of warfare has long since faded from time, and much of history has turned into legend. Yet, even as a legend, it is clear that arrogance, deceit, and avarice are the reasons for endless conflict among people, though gold takes the wrongful blame as its source. Just like those resplendent years untouched by strife, white iron and bronze were originally ritual offerings to gods. It was only later that they were cast off from altars and melted into armaments, becoming even more fearsome metals than gold.

The dragon in the story has been subjugated, right...? The wars among the cities are also near waning. The wandering poet's travels bring her to the holy city, where she plays the tale of the aftermath — After the evil dragon occupies the city, people rally dragon-hunting braves to rescue the princess.

"Lament for my homeland...
The courageous centurion, with shackles forged in heavy gold, finally subjugates the evil dragon.
The old ruler's cries can be heard from the tower-top...
From the dragon's belly, only scant parts of the devoured princess are found, where only bones remain."

The metal bracelet's tassels run across the lyre, emitting a crisp sigh.

Poet's Star-Studded SkirtBody

Dawn is the gentlest time of the day, her skirt is coincidentally also the colors of the last string of stars before dawn.

"When Aquila opens their eyes, all the stars are asleep. Only one squinting night star remains, being the most curious."

The narrative poem continues till the second cycle of day and night. More listeners gather around the poet, among them Kremnoans with quivers clinking with arrows, and those from Janusopolis who cast divining rods for godly advice. Since the black tide's encroachment across cities, countless historical records have been scattered, and the Grove's scholars have had little time to collect all the documents — many lesser cities did not even get the chance to leave their names behind.

Only the wandering poet knows that the old city occupied by the evil dragon once possessed the esoteric method of alchemy: With flesh as the foundation, everything could be created, and miracles could be performed. The alchemists spoke as such to the king, heartbroken from the tragic loss of his beloved daughter.

"Lament for my homeland...
The silver-tongued alchemist was confident he could resurrect the princess from the dragon's flesh.
What is dead, yet undead. Another ten days pass.
The ritual is finally complete, alas..."

The final nighttime star reluctantly closes its eyes, hankering to listen to the incomplete story of the children of humankind.

Poet's Silver-Studded ShoesFeet

Woven shoes inlaid with silver studs, pressing worded patterns across the sand she treads. On her mission to gather all the poems of the past, she has never once ceased her footsteps.

"The people know not where to seek Thanatos' trail, and there are legends that say no living can cross the River of Souls. Where, then, does the river flow?"

"We have never heard of such a dragon, nor come across the existence of resurrection rituals in ancient tomes" — Some doubtful among the listeners voice out. The poet replies — She is not an offspring of the old cities, therefore not certain whether there was truly an evil dragon. This is merely what she heard from earlier bards, a poetic song imparted along generations only through words.

If no one passed down the songs, the history of the old cities would be truly buried in dust, and all would fade with time — The flourishing city-state of the past, deluged and devoured by the River of Souls, becoming a place disdained by even wild hounds and circling vultures. This is the curse left behind by the souls eaten by the evil dragon.

"Lament for my homeland...
O Princess! Who would have imagined she was alchemied into the evil dragon's visage.
She devoured them all... the alchemist, the brave centurion, and the foolish king.
A feast fueled by bloodlust invited the shadows of death, the old city therefore annihilated..."

Remember the name of the decimated city! This is a story about Styxia, played by the poet wearing silver-studded soles. She collects stories for the stories themselves, just like the words left behind by the silver studs on her woven shoes — "Remember the story. Forget me."

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.
