Relic Sets

Every character wears exactly 6 Relics, split into two groups that can never swap slots with each other. Cavern Relics take up 4 fixed slots — Head, Hands, Body, Feet — and drop from the Cavern of Corrosion. Planar Ornaments take up only 2 slots — Planar Sphere and Link Rope — and drop ONLY from the Simulated Universe; caverns never carry this type at all.

• Cavern Relics carry both a 2-piece and a 4-piece bonus: wearing 2 pieces of the same set unlocks a lighter bonus, wearing all 4 unlocks a much stronger one. Since there are only 4 slots, you pick one of two splits: commit all 4 to a single set, or split 2+2 across two different sets.
• Planar Ornaments only ever give a 2-piece bonus: with exactly 2 slots total, you always wear one complete 2-piece set here — there is no 4-piece option, and it never mixes with Cavern sets.

Put simply: a character's full 6-piece loadout is always a 4-piece Cavern set (or 2+2 from two Cavern sets) plus a fixed 2-piece Planar Ornament set — you never get to freely mix all 6 slots the way some other games let you.

The first two Cavern slots are always locked, no choice involved: Head always rolls flat HP, Hands always rolls flat ATK. The other four slots are where the main stat rolls randomly from its own pool:

• Body: 7 options — HP%, ATK%, DEF%, Crit Rate, Crit DMG, Effect Hit Rate, Outgoing Healing Boost.
• Feet: 4 options — HP%, ATK%, DEF%, SPD. This is the ONLY slot that can roll SPD as a main stat.
• Planar Sphere: 10 options — HP%, ATK%, DEF% plus all 7 Elemental DMG Boosts (Physical, Fire, Ice, Lightning, Wind, Quantum, Imaginary). This is the ONLY slot that can roll Elemental DMG.
• Link Rope: 5 options — HP%, ATK%, DEF%, Break Effect, Energy Regeneration Rate. This is the ONLY slot that can roll Break Effect or Energy Regeneration Rate.

Pick by role: standard DPS wants ATK% or Elemental DMG on the Sphere plus Crit Rate or Crit DMG on the Body. Super Break teams prioritize SPD on Feet and Break Effect on the Rope instead of Crit. Supports or tanks usually want DEF%/HP%, and healers should hunt Outgoing Healing Boost on the Body.

Each Relic holds up to 4 sub-stats, none duplicating its own main stat. A 5-star Relic can be leveled up to +15, and every 3 levels (the +3, +6, +9, +12, +15 checkpoints) adds or upgrades one sub-stat — 5 checkpoints total for a piece taken all the way up. If a piece drops with only 3 sub-stats rolled, one of those 5 checkpoints is spent rolling in a brand-new 4th line instead.

• Standard/Crit DPS: prioritize Crit Rate, Crit DMG, then SPD for an earlier turn.
• Super Break: prioritize Break Effect and SPD, largely skipping Crit entirely.
• DoT or RES-shred roles: prioritize Effect Hit Rate so debuffs land reliably.
• Support or healer: prioritize SPD and Energy Regeneration Rate to fire Ultimates more often.

To compare two pieces fast without doing the math yourself, use Crit Value = 2 x Crit Rate% + Crit DMG% (counting only that piece's own Crit sub-stats), or plug the stats straight into the site's Relic Score (CV) tool for an instant score and grade.

The most common formula is one main 4-piece Cavern set plus the fixed 2-piece Planar Ornament — four pieces for the big bonus, and when you need extra base stats instead, split into two different 2-piece Cavern sets. But which set actually helps depends on the role of whoever wears it, not how strong the name sounds:

• Crit DPS: look for a 4-piece that directly adds Crit DMG or boosts damage from one specific attack type.
• Follow-Up or DoT: look for a set whose trigger condition matches the mechanic you're actually running (bonus attacks, or stacking damage-over-time).
• Super Break: look for a set that directly adds Break Effect or amplifies Break damage.
• Support: look for a set that restores Energy or buffs the whole team on Ultimate use — its value is feeding the team's rhythm, not personal damage.
• Healer or tank: look for a set that boosts Outgoing Healing, or raises shields/reduces damage taken for the team.

Since every 4-piece bonus has its own trigger condition, read the exact percentage in the table above before committing — a set that's great on one character can be dead weight on another if the trigger doesn't match its playstyle.

The two Relic groups drop from two completely separate sources, both spending Trailblaze Power but in different ways:

• Cavern Relics drop from the Cavern of Corrosion, gated by your account's Equilibrium Level — lower tiers still mix in plenty of 3 and 4-star filler, so push Equilibrium Level up before farming seriously to avoid wasting Trailblaze Power.
• Planar Ornaments drop ONLY from the Simulated Universe, and only from World 3 onward — after beating an Elite or Boss on a floor, interact with the terminal and spend 40 Trailblaze Power to claim the full set shown on screen.

To target the exact Cavern set you need instead of farming blind, use Self-Modeling Resin: gather 10 spare 5-star Relics (salvaged from pieces you don't use) to craft one piece of the exact set and slot you want, a feature that unlocks from Equilibrium Level 3 onward. General advice: don't rush Relic farming early in the game — spend Trailblaze Power on leveling characters and raising Equilibrium Level first, since higher tiers drop noticeably better gear and farming too early tends to waste your effort.
