I'm probably on my 12th run and haven't gotten one

1 ReplyTook me about 20. Think it is a 5% drop chance (but cannot drop on first run). So I was pretty much on par. Based on a little probability formula I wrote. (Probably wrong as school was a long time ago). Chance of having Crux drop by X runs is: 1 run 0% 2 runs 5% 3 runs 10% 4 runs 14% 5 runs 19% 8 runs 30% 11 runs 40% 14 runs 49% 19 runs 60% 25 runs 70% 33 runs 80% 46 runs 90% 59 runs 95% 91 runs 99% 136 runs 99.9%
