The best 2 examples that I can think of are Crystal (Prisoner) and O1. I have done tests because I was interested in this phenomenon. Whenever I teleport late to a Crystal or enter O1 much later and do less damage (boss is usually dead at that point), i always end up getting loot. But when I stay there since the beginning (even sometimes getting first hits) and deal more damage, my percentage of loot is like 1/10th compared to late damage. Is this intentionally in the coding or is it just weird RNG?
T.L.D.R.
Is more damage correlated to less loot on bosses like Crystal and O1? (I get the concept of RNG though)
