Characters Who Use This Set
2-piece or 4-piece?
Based on current data, 2 pieces are enough — no character is recorded as needing the full 4-piece bonus of this set, so you can mix it with another set on the remaining slots.

Sub-stats — value of one roll (5★)
Every +3 levels grants one roll, landing randomly on one of the three values below. These are the true values added to your stats; the in-game panel shows them rounded down.
| Stat | Low | Mid | High |
|---|---|---|---|
| HP | 33.9 | 38.1 | 42.3 |
| ATK | 16.9 | 19.1 | 21.2 |
| DEF | 16.9 | 19.1 | 21.2 |
| HP | 3.5% | 3.9% | 4.3% |
| ATK | 3.5% | 3.9% | 4.3% |
| DEF | 4.3% | 4.9% | 5.4% |
| SPD | 2 | 2.3 | 2.6 |
| CRIT Rate | 2.6% | 2.9% | 3.2% |
| CRIT DMG | 5.2% | 5.8% | 6.5% |
| Effect Hit Rate | 3.5% | 3.9% | 4.3% |
| Effect RES | 3.5% | 3.9% | 4.3% |
| Break Effect | 5.2% | 5.8% | 6.5% |
What main stat to run, by role
| 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
Grand Duke's Crown of NetherflameHead
Grand Duke's Crown of NetherflameA crown of unceasing flame, with its burning ambition serving as its inexhaustible fuel.
"I, born on the eve of destruction, am the sinful belief of Fetora. I am the furious flames of Nanook."
Nanook destroyed Fetora by THEIR own hands, and the White Star's flames coalesced with the power of Destruction to birth a plasmic lifeforms. The elegant fire demon saw its birth as a revelation. "Today, the Lord of Destruction conquered Fetora. THEY honored it with blazing flames. The frivolous and meaningless glory evaporate with the solar flare, but concrete and heavy glory shall mark my coronation." Ifrit has been obsessed with destruction and slaughter since birth.
"The laurels of honor in this world are all woven of thorns. The only laurel that surpasses these thorns is my supreme crown of netherflame."
The embers left behind from the Aeon of Destruction's annihilation of a star were clasped in Ifrit's own hands, molded into the shape of Fetora's crown, and worn to this day.
Grand Duke's Gloves of FieryfurHands
Grand Duke's Gloves of FieryfurPure white gloves with flames as its fur, hiding its brutality under smooth silk.
"I come with Destruction's revelation. One hand giveth, and the other taketh away."
Firmly believing that "the preciousness of something can only be appreciated in its eradication," Duke Inferno torched the history and culture of the planet Lisalit, scorching the brilliant silks of the aristocracy, incinerating the long scrolls of the poets, razing the vivid murals of the painters to ash... "Civilization is like a larva. It will only be reborn in a burning execution, when it turns into a black butterfly that flutters away in the wind." Like an undertaker who lowers their head to monitor the crematorium's furnace, Ifrit guides civilizations into their swansong.
"Through my efforts, imagination, and direction... the synchronization, number of performances, tone, and tempo of the different catastrophes... all fuse into a brilliant masterpiece of destructive performance."
After the end of a satisfying destruction, Ifrit wipes the blood off their hands and dons pristine white gloves again, as if they were an aristocrat attending a banquet.
Grand Duke's Robe of GraceBody
Grand Duke's Robe of GraceA gorgeous robe that emphasizes the dignity and elegance of its owner.
"The purpose of clothing is not to adorn one's appearance, but to display one's true essence — just as the essence of flame is to destroy."
The ever-burning clan of fire demons regards Nanook as their emperor and savior, but the Aeon had never glimpsed at them. Ifrit's destruction is laced with flaunts, power, conquest, and motivation, and the rivalry between the Ever-Flame Mansion and the Jepella Brotherhood was even more sordid. "Impure destruction stains the most magnificent garments more easily than dirt." Regarding purity, Ifrit has never been able to grasp its essence from the start.
"The value of destruction lies in the value of the thing destroyed. Our value lies in our practice of Destruction until our emperor takes notice."
Ifrit, with piety in their heart, wears brocaded garments woven with velvet-red flames, and waits for the summon of the Destruction.
Grand Duke's Ceremonial BootsFeet
Grand Duke's Ceremonial BootsA pair of classic and comfortable boots in pristine condition, with a sleek design and flattering style.
"Those who have no roads left to walk on don't need boots. Why must these civilizations at their end whinge at me?"
Duke Inferno, with the crown of fire on their head, is considered by many civilizations as an otherworldly demon, yet receives an invitation from the planet of festivities. Ifrit is happy to attend in full ceremonial garb. "I will prepare a courteous and thoughtful destruction, and not a single bone will be left behind." The elegant fire demon assembles a party of cosmic evil, and plans the grandiose scene of offering a mountain of corpses and a sea of blood for the banquet... Those destroyed civilizations are but mere stops on the pilgrimage to Destruction, and Penacony will just be another pit stop along the way.
"Your destruction is nothing personal. It is just for the purpose of earning THEIR gaze."
At the sound of the distant banquet calling, Ifrit cheerfully embarks on the long journey to the feast.

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.
