Wuthering Waves uses a soft-pity system: 5★ probability is 0.8% base but ramps up sharply around pull 66, with hard pity at 80. The featured Resonator banner uses a 50/50 mechanic — if you lose the 50/50, the next 5★ is guaranteed to be the featured character. The weapon banner has no 50/50: the featured weapon is always 100% on every 5★.
How the math works
We simulate the probability distribution starting from your current pity, using the published soft-pity ramp (probability rises from 0.8% to roughly 75% between pull 66 and 80). For multi-copy targets, we compound the expected pull count using the geometric/negative-binomial distribution. The 50/50 result is averaged in for the character banner.
Astrite economy reference
1 pull = 160 Astrites (or 1 Tide directly)
F2P daily average: ~60–80 Astrites from dailies, events, and exploration
Per patch (6 weeks): ~12,000–16,000 Astrites for a F2P player = 75–100 pulls
Soft pity hits: ~75% of 5★s come between pull 66 and 80
Pulling tips
If you are at 60+ pity, push to soft pity now even if you don't want the current banner — guaranteed 5★s carry over.
Never pull a weapon banner unless you have at least 80 Forging Tides saved. The hard pity is your guarantee.
For S6 (max chain) targets, expect 480–600 pulls including weapon. Plan 2–3 patches of saving.
