Wuthering Waves Tools

Every 5★ pull in Wuthering Waves starts at a base 0.8% rate on both the character and weapon banner, with a hard pity at 80 pulls guaranteeing a 5★ — but soft pity kicks in around pull 66, where the real odds climb sharply toward that guarantee. A 4★ or higher is also guaranteed every 10 pulls, so those never get lost.

• On the character banner, a 5★ pull is a 50/50: lose it once and the very next 5★ is guaranteed to be the featured character.
• On the weapon banner, there's no 50/50 at all — every 5★ that drops is the featured weapon.
• Pity and the 50/50 guarantee both carry over between banners of the same type, so nothing resets just because a banner ended.

Plug in your current pull count and this calculator shows your real odds for pulling the featured 5★ before you spend a single Astrite — the same math behind it is verified against Kuro's own published rates.

Instead of spitting out one number and asking you to trust it, this calculator shows the full chain behind your damage: ATK_total × Skill% × (1 + total DMG Bonus) × (1 + total Deepen) × Crit multiplier × DEF modifier × RES modifier. Every factor is its own line, so you can see exactly which stat is doing the work.

• Deepen (DMG Amplify) multiplies against regular DMG Bonus rather than adding to it — two separate 30% buffs stack to roughly +69%, not +60%, and the calculator shows that math instead of hiding it.
• Crit starts at a 5% base rate and 150% base damage; most builds aim for a rough 1:2 Crit Rate to Crit DMG ratio, landing Crit DMG somewhere around 200-240%.
• The DEF modifier is labeled as a community-measured estimate (roughly 52% against a same-bracket enemy) rather than an official closed formula, since Kuro hasn't published one — the calculator flags this instead of pretending it's exact.

Use it after you've picked a weapon and echo main stats, to compare two loadouts side by side before committing Tuners to either one.

Every Echo has up to 5 substats, and judging whether one is worth keeping shouldn't require memorizing a spreadsheet. This scorer publishes its full weighting up front — nothing hidden — split by role:

• DPS: Crit Rate 2.0, Crit DMG 1.0, ATK% 0.75, matching skill-type DMG% 0.75, flat ATK 0.25, Energy Regen 0.25, HP/DEF weighted 0.
• Sub-DPS / Buffer: same as DPS, plus Energy Regen weighted 0.75.
• Healer / Support: HP% 1.0, Energy Regen 0.75, DEF% 0.5, flat HP 0.3, Crit Rate/Crit DMG only 0.1.

The score also reports Crit Value (CV), calculated as 2 × Crit Rate + Crit DMG — the same shorthand the wider community uses to compare rolls at a glance. A score of 70 or higher is graded A (worth building around), 60+ is B, and anything under 45 falls to C/D and is usually safe to feed or discard.

One honest limit worth knowing: this weighting is a published rubric, not a hidden constant baked into the game itself — if your build leans on an unusual skill-type scaling (say a Frazzle-focused kit), weigh that skill-type% substat a little heavier than the default before trusting the score blindly.

These three tools line up with the three stages every build actually goes through.

• Before you pull: open the pity calculator first, check your real odds on the banner you're eyeing, and decide whether to pull now or wait for a fresh guarantee reset.
• After you've pulled and chosen gear: run the damage calculator with the weapon and echo main stats you're considering, comparing two loadouts side by side before spending Tuners — pair this with a character's own build page or a team page for the recommended sonata set and rotation first.
• After a Tacet Field or open-world farming session: score every echo that dropped before you decide what to feed and what to keep — a mediocre 3-cost is easy to miss without a number attached to it.

Run them in that order and you spend Astrite, Waveplate, and Tuners on decisions you've actually checked instead of ones you guessed at.

The pity calculator, damage calculator, and echo scorer are live today, but they're not the end of the roadmap. A few more tools are in the works:

• Material planner — total up how many Tacet Field runs, Waveplate, and leveling materials a full character build actually needs.
• Build card generator — turn a finished build into a shareable summary card.
• Pull-history tracker import — pull in your own gacha history instead of entering pity counts by hand.
• Interactive map — pin every collectible and Tacet Field location across the open world.

None of these are live yet — they're genuinely still in the works, so no release date is promised here. The three tools above are ready to use right now.
