Paradino Mine Boss Loot Table Bug (Vergoltung)
While mindlessly grinding QCs, I observed that the loot contradicts that of the stated loot table. Specifically:
- I received 2 copies of Book of Ice Shards in a single kill, despite the loot table indicating that only 1 book can drop per run.
- Across 25 tracked runs (plus ~35 prior unlogged runs, not including savescumming attempts), I received:
- 0 copies of Glacial Prison (10% drop rate)
- 0 copies of Ice Age (5% drop rate)
Statistically, this is highly improbable. Based on expected probabilities, at least a few rare book drops should have occurred. This suggests a possible bug where rarer book rolls are being overwritten by Ice Shard.
Steps to Reproduce:
- Battle Vergoltung repeatedly. (Or save just outside the boss room and rerun the fight many times)
- Track loot drops across multiple runs.
Supporting Data: I’ve compiled a loot tracking spreadsheet to estimate drop rates.
While the sample size is modest, the Ice Shard drop rate appears inflated, and the complete absence of other books is concerning.
Probability Context:
- Chance of not getting Glacial Prison in 25 runs: ~7.2%
- Chance of not getting Ice Age in 25 runs: ~27.7%
- Chance of not getting either: ~2%
Although it could mean I have astronomically awful rng (Approx 0.2% no Glacial Prison and 5% no Ice Age across ~60 runs), I'm pretty certain that there shouldn't be duplicate book drops.
