The table shows the cumulative odds of getting at least one item given a 0.1% drop rate (one in a thousand)

I.E. a 1/1000 drop rate does not mean that if you kill 1000 you WILL get one; rather since the chance is 0.1% each time you kill the mob, then the odds of getting at one from N kills is 100% minus 99.9%^{N}. Furthermore, since the cumulative odds never quite reach 100%, it is possible—albeit unlikely—to never get one.

Number of Kills | 100 | 288 | 401 | 693 | 1386 | 2302 | 2995 | 4603 | 9206 |
---|---|---|---|---|---|---|---|---|---|

Cumulative Probability | 9.5% | 25% | 33% | 50% | 75% | 90% | 95% | 99% | 99.99% |

Neither the drop rate nor cumulative probability increases based on the number of monsters you have already killed. |
