Duet Night Abyss Pity Calculator · Pull Planner
Real odds on the featured 5★ — pulls for 50%, for 90%, and for the guarantee, and the expected spend
81 typical, 156 if unlucky, 94 on average — guaranteed by 180. Plotted on the same axis as every other game.
Duet Night Abyss's featured Chrono: 0.6% base 5★ and a 1.6% comprehensive rate including pity, hard pity at 90 with a 50/50 on the featured character.
The base rate and the pity count are the figures the game itself states. The shape of the soft-pity ramp between them is this planner's model, calibrated to reproduce the stated odds — treat the exact per-pull curve inside the ramp as an estimate, and the totals it produces as the game's own numbers. Checked against Duet Night Abyss 1.5.190 on 2026-08-19.

Starting from zero pity — the actual numbers
If you open the banner with no pity carried over, this is what a featured 5★ costs. The planner above adjusts these for the pity you already have.
| Outcome | Pulls | Hourglass |
|---|---|---|
| 50% chance | 81 | 81 |
| 90% chance | 156 | 156 |
| Expected (average) | 94 | 94 |
| Guaranteed by | 180 | 180 |
Base rate 0.6% per pull, with the soft-pity ramp beginning at pull 74 and a hard guarantee at pull 90. A first win is 50/50 against the featured unit, so a loss puts the next top-rarity pull on guarantee. “Expected” is the mean across the full distribution, not the median — half of players get there sooner than the 50% row, and a long tail does not.
