Lushaka, the Sunken Seas
The effect only matters for a support standing outside the first slot to grant 12% ATK to the lineup's first character, a lineup-order-dependent condition that keeps it niche.

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% |

| 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
Lushaka's WaterscapePlanar Sphere
Encapsulated in the plane is a submerged city in the marine world Lushaka. The sea level rose to the point where even the city was drowned. Only gigantic "stateships" carrying their sailors chug along across the sea, in search of the direction for their next distant voyage.
At the break of dawn, the first mate of the "stateship" gently knocks on the Captain's quarters door, and pushes it open. The island ecologies of the Old Era's thirty-seven domains are stuck on the walls all over the cabin. That is how people miss land — meteors from beyond the skies are in the process of covering the entirety of Lushaka with water as if following some single-minded wish. Unending tides bury all ancestral lands in abyssal waters, leaving only an expanse of blue... The first mate rouses the sleeping Captain, for the sea is already glinting specks of gold — the "stateship" has begun another day's voyage.
The scouting ship arrives at the center of the plaza. It fires its anchor arrow towards a massive underwater structure that was once a shopping mall. The anchor firmly lodges itself on a window frame — before the diving bell comes, countless startled schools of fish surge forth from the shopping mall's shelves.
After midday, the scholars leave from the diving bell. They swim past the bookstore, not stopping even for a second — after all, the ink would have long been blurred beyond recognition. Their goal has always been those mediums of shellac or plastic, from which information of past days can be easily obtained after easy cleanup. Deepsea archaeology like this is always arduous. The cleaners stand their ground and watch the vicinity alertly, steel halberds swinging, ensuring that toothy predators are kept at bay. The humans will occasionally collide with deepwater aqua sprites, but both parties are too engrossed in their respective scavenging to pay each other any heed. Instead of shriveled cans, the cleaners are more invested in finding seeds, spices, or liquor.
The intensive underwater investigation is nearing its end as the oxygen reserves decline. Looking back underwater, the giant mackerels have already reached the city. The anxious aqua sprites immediately hold their breath, hug the wall, or hide in secret chambers. They have grown used to utilizing the underwater steel forest.
The drizzle lets up as the sun starts to sink, and the various stateships sound their horns to scatter the plundering seabirds around them. They place the day's harvest on the deck for the stateship's citizens to take what they need. Currents surge at night as the light tower shines crystalline bright. The Luvians dance around the flaming mast, forgetting the tomorrow that will inevitably come, recounting the glories of today with sea shanties, and sighing softly to the halcyon past with medleys. The Captain takes out his compass, gazing toward the direction it points — he knows in that direction lies their home that is growing ever more unfamiliar, where there are still people longing for the return of their kin.
At midnight, the colossal ship extinguishes all its lights, silently adrift upon the sea. Have they truly found peace? Or are their smiles masking the tears that have long dissolved into the sea?
After tonight, this deep blue will remain unchanged, as it always has.
Lushaka's TwinlanesLink Rope
On the boundless horizon, even the faintest mark can shatter this silence. The navigational lanes bear the history of the crew while the aqua sprites pursue hope along the water currents.
The land-dwellers of Lushaka have an intimate yet unfamiliar relationship with the aqua sprites. In deepsea investigations, the land-dwellers view encounters with the aqua sprites as lucky omens, describing the spirits as beautiful and mysterious creatures. Aqua sprites possess navy blue wing membranes and onyx eyes, as well as unique vocal cords capable of producing ethereal sounds. According to stories passed down by mouth among the deepsea investigators, these creatures often accompany sea dragons and reside in a silvery city deep underwater — they exist between reality and legend, embodying serenity and liveliness.
However, the language used to describe them in the ocean-drowned past was — Edars, monsters of the deep sea.
Long ago, the Edars and the land-dwellers fiercely vied for survival. No one could ignore the vivid red the oceans were dyed into. Initially, juvenile Edars were regarded as mere fishing catches. Then, the land-dwellers were lured into the ocean to drown by the songs of the Edars. Both races were hunters and prey for the other in the vast waters. Then came clashes between blades and anchors, as well as battles between sea beasts and cannons. The relentless war, both above and below the water's surface, persisted until the reefs shattered under scorching magma. It was only after a long time that stateship scholars understood that the Cancer of All Worlds has long promised Lushaka's future — only that the promises came from an aqua sprite who lost her home, who cursed the culprit in the nightmare with a silent scream.
The long-forgotten past lies entombed within the steel and concrete coral reefs of the deep sea, as ephemeral as smoke and clouds, known to none.
Since then, cities and lands have been swallowed by the sea, disputes and blood have been consumed by the ocean, and history and civilization engulfed by the waves. To escape rising deep-water pressure, the aqua sprites constantly migrate upward, compelled to dwell in cities once home to land-dwellers, prying into memories filled with smiles and tears... They know that few sounds remain on the surface, and the azure now belongs to them alone. Yet, the silence is too overwhelming.
When the stateship's songsters glimpse azurean silken wings along their nautical course, they will start to sing that beautiful medley...
"They journey along the course, in pursuit of the light tower and storm, seeking only to reclaim that pure blue."

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.
