Relic Score (CV)

The tool uses Crit Value (CV) = Crit Rate% × 2 + Crit DMG% to quickly measure how good a relic's crit lines are. The ×2 coefficient isn't arbitrary: three independent sources confirm the same ratio — Fribbels Star Rail Optimizer (open source, potentialScale shows Crit Rate = 6.48/3.24 = 2× Crit DMG), the Korean community's per-roll score table on arca.live (Crit Rate 2.92% = 1 point, Crit DMG 5.83% = 1 point, same 2:1 ratio), and Japan's Altema (states the ideal Crit Rate:Crit DMG ratio is 1:2).

The root reason: the highest single-roll value of Crit DMG (6.48%) is exactly double that of Crit Rate (3.24%), so 1% Crit Rate is always worth 2% Crit DMG at any roll tier.

Every substat has its own highest-possible-roll value for 5★ relics, used to convert whatever value you enter into "how many perfect rolls is this worth." The tool's MAX_ROLL table matches Fribbels' published high-roll table exactly: Crit Rate 3.24%, Crit DMG 6.48%, SPD 2.6, ATK%/HP%/Effect Hit Rate/Effect RES all 4.32%, DEF% 5.4%, Break Effect 6.48%, while flat stats (raw HP/ATK/DEF) sit noticeably lower since they don't scale off a % base. A maxed +15 relic carries about 9 "roll lines" spread across its 4 substats (4 initial lines + 5 upgrades) — the tool uses this exact number to compute roll efficiency.

The HSR community runs two entirely different scoring philosophies side by side, which is why two tools can show very different numbers for the exact same relic even though both are "correct":

• Weighted roll-value (the community school, Fribbels): sums each substat's value converted via MAX_ROLL, multiplied by a role weight. Fribbels and the Korean arca.live score table both follow this approach — this page currently scores raw CV + roll efficiency, NOT yet multiplied by a role weight.
• Value/theoretical-max (the Japanese appmatch/Otameta school): divides the ACTUAL substat value by a theoretical maximum (the sum of every possible roll at +15, e.g. Crit Rate theoretical max 19.4%, Crit DMG 38.7%), then multiplies by weight, producing an absolute score scale (e.g. Otameta's 55 points per piece, SSS 6-piece at 262+).

Both philosophies rank relics equivalently — they don't contradict each other — they simply normalize and display numbers differently. So: don't compare this page's "grade S" or "score 50" threshold against another tool's threshold unless you know for certain it uses the same formula; each tool has its own scale, and grades should only be read within the tool that produced them.

The fastest way is pasting your UID into the input so the page automatically pulls the relics currently equipped on each character in your build — no manual substat typing needed. Once the list loads, pick a character then pick the relic you want to score; the tool auto-fills the main stat and recorded substats from that build into the form.

Without a UID (or to test a hypothetical relic), enter up to 4 substats manually: pick the correct stat name from the dropdown and type its % value — the tool recalculates instantly on Enter, no separate submit button needed.

The result has 3 parts: a letter grade (S/A/B/C/D) based on raw CV — S at CV 45 or above, roughly a relic with both crit lines near-perfect; the CV number itself is Crit Rate×2 + Crit DMG added together; and a roll-efficiency bar (%) measuring the total "perfect roll equivalent" across all 4 substats against the 9-roll maximum of a +15 relic.

The breakdown lists how much each substat contributes to the total — whichever line carries the biggest share is what's driving the CV score up (or down). A substat that isn't Crit Rate/Crit DMG does NOT add to CV but still counts toward the overall roll-efficiency bar — the two numbers measure different things, don't conflate them.

Said plainly so you can judge for yourself: this page currently scores CV as generic "crit quality," and does NOT yet apply per-character weights across the roster. Every strong community tool (Fribbels, Otameta, HSR Statistics, game8) keeps a separate weight profile per character — a support character, for instance, needs SPD/Break Effect/DEF% more than crit. Because this tool only scores generic crit-CV so far, a relic with strong SPD or Break Effect for a support character MAY score a low CV grade even though it's actually right for that character's build.

How to compensate while you wait: if you're building a support, a Break-focused Rupture unit, or any character that doesn't need crit, don't rely on this page's S/A/B/C/D grade to decide keep-or-scrap — compare its SPD/Break Effect/DEF%/Effect Hit Rate value against what that character actually needs, and only trust the CV grade when the character genuinely wants crit stats. Adding per-character weighting is a future improvement that NEEDS MANUAL UPDATING — it isn't built yet, and this page doesn't claim otherwise.
