About WuWa Tools
WuWa Tools is a free, browser-based toolkit and guide collection for Wuthering Waves (鸣潮) — Kuro Games' open-world action RPG. We launched in 2026 because we were tired of clunky echo-grading spreadsheets, region-locked tier lists, and pull calculators that get the soft-pity math wrong.
What we believe
1. Math first, opinion second.
Every number on this site comes from the in-game data tables. Substat roll ranges, soft-pity probability curves, character ascension costs, and Forte skill upgrade tables are all coded from the actual game values — not estimated, not crowdsourced from reddit threads. If you want to verify, every formula is visible in the JavaScript source of each tool.
2. Your data stays in your browser.
WuWa Tools does not have a backend database. When you enter echo substats into the Echo Scorer, those values are processed in JavaScript locally and never sent to a server. We can't see your account, your pull history, or your build because we don't store them.
3. Built for global players from day one.
Wuthering Waves is a global game. The tier lists and meta opinions you see on most English sites assume the global server's meta — which sometimes lags China by months. WuWa Tools supports English, Simplified Chinese, Japanese, and Korean out of the box, with terminology cross-checked against each region's official client.
The tools
- Echo Scorer — Grade any echo's substats from S to D against role-based weight presets (Crit DPS, Liberation, Heavy Attack, Sub-DPS, Healer). Tells you whether to spend Tuners before you waste them.
- Pull Calculator — Compute exact pull counts, Astrite budgets, and confidence intervals (50%/90%/99%) for both character and weapon banners, with soft pity and 50/50 modelled correctly.
- Material Planner — Plan ascension and Forte skill leveling: every Shell Credit, XP potion, boss drop, and Forte material needed for your target character build.
The guides
We publish long-form guides covering the topics tools alone can't answer — when to skip a banner, which Sonata set actually fits each character, the real ER breakpoints for each rotation length, and so on. Read the latest:
- Echo Main Stats Guide: Best 4/3/1-Cost Per Role
- Pull Strategy 2026: How Many Astrites for Guaranteed 5★
- Sonata Set Tier List: Which 5-Piece Set for Each Character
- Echo Farming Routes: Best XP & Tuner Efficiency
- Energy Regen Breakpoints: When You Actually Need More ER
How we're funded
WuWa Tools is supported by a small number of discreet display ads (Google AdSense). We deliberately keep the tool pages ad-light so you can input substats without the page jumping around. There are no paywalls, no premium tiers, and no plans to add any. If you want to support the site directly, the best thing you can do is share it with your guild or community.
About the team
WuWa Tools is built and maintained by a small team of Wuthering Waves players. We're based in Asia, we play on multiple regions, and we keep up with the patch cycle the same way you do — by reading datamines, watching Bilibili showcase videos, and pulling like idiots whenever a hyped character drops.
