What Wuthering Waves pulls actually cost you in probability
Wuthering Waves does not run independent pulls. The base rate is 0.8% per pull, but a soft pity starts at pull 66 and the 80th pull is guaranteed. That single fact is why a flat probability formula gives the wrong answer — and why most players misjudge their odds.
At a flat 0.8% the chance of at least one 5★ inside 80 pulls would be 47.4%. With pity in play it is 100%: the guarantee does the work. Half of all players hit by pull 67; 90% hit by pull 72.
Pull-by-pull breakdown
Chance of at least one 5★ in Wuthering Waves, by number of pulls
| Pulls | Chance of at least one 5★ | Chance of nothing |
|---|---|---|
| 10 | 7.7% | 92.3% |
| 20 | 14.8% | 85.2% |
| 40 | 27.5% | 72.5% |
| 60 | 38.2% | 61.8% |
| 80 | 100.0% | 0.0% |
Why the plain formula undersells you
A simple 1−(1−p)ⁿ model assumes every pull is identical. Between pull 66 and 80 it is not: the rate climbs by 6.0 percentage points per pull, so the last stretch is worth far more than the first. Use the table above for planning, and the pity calculator when you want 50/50 and guarantee scenarios modelled explicitly.
