About this Wuthering Waves Echo Scorer
Wuthering Waves echoes have randomized substats, making it hard to tell whether to spend Tuners on a fresh drop. This tool uses real in-game substat roll ranges and role-based weighting to give you an objective score.
How the scoring works
For each substat you enter, we calculate how close it is to its maximum possible roll, multiply by the role-specific weight, and normalize against the theoretical best 5-substat combo. A score above 70 (A grade) generally means the echo is worth leveling to +25.
When to level an echo (and when to skip it)
Tuners are the bottleneck on echo progression — you get about 30 from a daily reset, and a single +25 4-cost echo costs around 75 Tuners. That means roughly 2.5 days of dailies for one fully-leveled echo. Don't waste this on a random drop. Use the score above 70 (A grade) as the keep threshold for a 4-cost echo on your main DPS, and 60 (B grade) for sub-DPS or healer slots where stat compression matters less.
For a fresh +0 echo with the correct main stat, the score is computed from substat rolls and your role preset. Re-rolling the substats happens at +5, +10, +15, +20, and +25 — five chances total. If your +0 echo already shows two priority substats (like Crit Rate and Crit DMG for a Crit DPS preset), it's almost always worth leveling. If it shows zero priority substats, skip it: the odds of unlocking all four priority substats in five tries are too low to justify the Tuner cost.
5 common mistakes when grading echoes
These five mistakes show up in nearly every "did I make the right call?" thread on Reddit and Discord. Avoid all five and your echo planning will be cleaner than 90% of players.
1. Treating any S-rank as auto-keep. An S-rank echo with the wrong main stat is still worse than a B-rank with the right main stat. Always check the main stat against your role preset first. A 4-cost with HP% on a Crit DPS character is a hard skip even if the score reads 90.
2. Ignoring sub-stat ceiling math. Each substat type has 8 possible roll values. A Crit Rate roll of 10.5% is the maximum; a 6.3% roll is the minimum (and almost worthless). The score factors this in, but new players often see "Crit Rate" appear and assume it's good without checking the value.
3. Leveling before all 4 substat slots unlock. Substats unlock at +0, +5, +10, +15, and +20. A 5th substat appears at +25. You only know the full picture after +20 — and by then you've spent most of the Tuners. Reading the +0 score is the only chance to make a smart investment decision.
4. Using the wrong preset for the character. A Liberation DPS like Calcharo doesn't value the same substats as a Crit DPS like Jiyan. Using the default Crit DPS preset for everyone will systematically over-rate Liberation-scaling echoes for Crit characters and under-rate Liberation substats for Liberation characters.
5. Not factoring 4-cost slot scarcity. Your team only has four 4-cost echo slots total (one per character). Filling a slot with a B-grade echo isn't a tragedy if you have nothing better — leave it and let the +5/+10 rolls decide. Re-rolling 4-cost slots costs the most because the main stat itself has many options.
Frequently asked questions
Should I level a B-grade echo if I have nothing better?
Yes, but only to +15. Stop there, check the score again, and decide. Going +15 → +25 costs about 50% of the total Tuner budget for one echo — that's the expensive half. A B-grade at +15 is usually better than no echo at all, but the marginal damage gain from +15 → +25 isn't worth it unless the substats hit at least two priority rolls.
How does the role preset change the score?
Each preset assigns weights from 0 to 2.0 to each substat type. Crit DPS weights Crit Rate at 2.0, Crit DMG at 1.0, ATK% at 0.75, and zero for HP/DEF stats. Healer flips this: HP% at 1.0, Energy Regen at 0.75, Crit weights drop to 0.1. The final score multiplies each substat's value-vs-max ratio by its weight, then normalizes to 100. Different presets can give the same physical echo wildly different scores — pick the preset that matches the actual character.
Why does the same substat value get different scores on different echoes?
The score is normalized against the theoretical best 5-substat combo for that preset. A Crit Rate roll of 10.5% on an echo that already has Crit DMG, ATK%, and Energy Regen scores higher than the same Crit Rate roll on an echo with only HP%-junk fillers. This is correct behavior: the value of any substat depends on the company it keeps.
When is it worth re-rolling a 4-cost main stat?
Almost never. Re-rolling consumes the echo entirely. You'd need to farm a new 4-cost (1-2 hours of Waveplate), tune it (more Tuners), and hope for both a better main stat and at least 2 priority substats at +5. The math says: keep any 4-cost with a correct main stat and at least one priority substat at +0, and re-farm only if the main stat itself is wrong (ATK% on a Liberation character, HP% on Crit DPS, etc.).
Build presets explained
- Crit DPS — Standard double-crit build, prioritizes Crit Rate and Crit DMG.
- Liberation DPS — Burst-focused, values Liberation DMG% and Energy Regen.
- Heavy Attack DPS — For Heavy Attack carries, values Heavy ATK DMG%.
- Sub-DPS / Buffer — Higher Energy Regen weight for off-field burst rotation.
- Healer — Prioritizes HP% and Energy Regen, ignores offensive stats.
