But that is only relative.
low LP chance uniques still have waaaaaaaaay lower chance to get LP than high LP chance uniques.
Relative to each other it might be that those super rare uniques have a higher chance to get LP, but in absolute value they have waaaaaaaaaay less chance.
I talked about it here:
Event Horizon is a very good item to practically test this behaviour in “larger” quantities.
Because it is very easy to obtain in large quantities but still has incredibly low LP chance (similar to super rare chase uniques like Red Ring, Ravenous Void or Omnis).
Yes 40 is still a pretty small sample size but I think it is enough to underline my point.
