How This HSR Relic Score Calculator Works
Every Honkai: Star Rail relic — Head, Hands, Body, Feet, Planar Sphere, or Link Rope — carries a fixed Main Stat and up to four random Substats. The Main Stat is deterministic, so it's the same on every copy of that piece at the same level; it's the Substats that are random, and it's the Substats this calculator grades. A maxed 5★ relic (+15) can have up to 9 total substat rolls spread across those four lines — that's the ceiling every score here is measured against, matching the convention used by every community relic scorer.
Pick a Build Role (Crit DPS, Break DPS, SPD/Support, or HP-DEF Sustain), enter a relic's substats, and get back a Roll Value % (how lucky the piece rolled, regardless of role), a role-weighted Score % (how good it actually is for that build), and a Substat CRIT Value figure — for a single piece, or a full 6-piece build.
The 9-Roll Ceiling, Visualized
Every gear slot can carry up to 4 substats. Across a relic's full life from +0 to +15, those substats share a combined maximum of 9 rolls. Roll Value % and Score % are both measured against that same fixed ceiling.
Head
Up to 4 substats
Hands
Up to 4 substats
Body
Up to 4 substats
Feet
Up to 4 substats
Planar Sphere
Up to 4 substats
Link Rope
Up to 4 substats
Shared Ceiling
9 rolls max at +15
Rolls Used
Value ÷ Avg Roll Value
Score %
Σ(Rolls Used × Role Weight) ÷ 9 × 100
Roll Value % ignores role entirely — it's a pure measure of how lucky a relic's overall investment was. Score % applies the selected role's per-stat weights, so the exact same relic can score very differently depending on whether it's being judged for a Crit DPS, Break DPS, SPD/Support, or Sustain build.
Roll Value %, Score %, and CRIT Value — What Each Number Means
Roll Value %
Total rolls used across all substats, divided by the 9-roll ceiling. Role-agnostic — it only tells you how lucky the piece is, not whether those rolls landed on stats you actually want.
Role-Weighted Score
The same rolls, but each one is multiplied by how relevant that stat is to your chosen Build Role before dividing by 9. This is the number that actually tells you whether a piece is good for the build you're running.
Substat CRIT Value
(CRIT Rate% substat × 2) + CRIT DMG% substat — the community-standard shorthand for how much raw crit a piece is carrying, counting substats only. Most useful on Crit DPS builds.
A relic can have a high RV% but a low Score% — that means it rolled well overall, just not into stats that matter for the role you selected. That mismatch is exactly what the calculator's Tips flag when it happens.
Why the Main Stat Isn't Scored
A relic's Main Stat is fixed by the game and grows on a deterministic schedule as the piece levels up — it's never random, so there's nothing to grade. Two Body pieces with the same Main Stat and the same level always have the exact same Main Stat value; only their Substats can differ. Every established relic-scoring convention grades Substats only for this reason, and this calculator follows that convention.
That said, Main Stat choice still matters enormously for a build — a Body piece with an off-role Main Stat (like HP% on a Crit DPS build) wastes the single highest-value stat slot on the relic, even if its Substats roll perfectly. The calculator still checks this: in Full Build mode, any piece whose Main Stat isn't ideal for the selected role gets flagged in the Tips section.
Role Weight Reference
Each Build Role weights the 12 possible substats differently. A weight of 1.00 means that stat is a perfect fit for the role; lower weights mean the stat is still useful but not the priority.
| Stat | Crit DPS | Break DPS | SPD / Support | HP-DEF Sustain |
|---|---|---|---|---|
| CRIT Rate% / CRIT DMG% | 1.00 | 0.10 | 0.10 | 0.05 |
| ATK% / ATK | 0.75 | 0.20 | 0.15 | 0.10 |
| Break Effect% | 0.10 | 1.00 | 0.15 | 0.10 |
| SPD | 0.50 | 0.75 | 1.00 | 0.40 |
| Effect Hit Rate% | 0.20 | 0.20 | 0.60 | 0.20 |
| Effect RES% | 0.10 | 0.15 | 0.40 | 0.50 |
| HP% / HP | 0.15 | 0.20 | 0.30 | 1.00 |
| DEF% / DEF | 0.10 | 0.30 | 0.20 | 0.70 |
A fifth role, Balanced / Hybrid, weights every stat at roughly 0.35–0.55 for a generalist build that isn't optimized around any single stat.
What Counts as a Good Relic Score?
85%+ Score — S+ (Endgame BiS) — near-perfect for the selected role, ready for the hardest content.
70–84.9% — S (Excellent) — strong, reliable, no meaningful weaknesses.
55–69.9% — A (Great) — a solid piece with room to improve one line.
40–54.9% — B (Good / Usable) — works fine, but multiple lines are off-role or under-rolled.
25–39.9% — C (Below Average) — usable as a placeholder while farming a replacement.
Under 25% — D (Reroll Candidate) — the substats are mismatched or barely rolled for this role.
These thresholds apply to both the single-relic Score % and the full-build average Score % — a Build Grade of S means the average piece in that build is performing at Excellent, not that every single piece individually hit S.
