do low level trophies have maximum quality which can be given out or is it unlimited? *Never had anything good from those
All drops and trophies have technically same maximum quality (1) that can be rolled. However, count the average number of stats that appear on your piece of equipment(Yeah, some have more but quality threshold values are accounted for that). Now take (0.05+0.1) to the power of the number( 0.05 indicating legendary threshold, 0.1 indicating crap loot bonus), then do that with (0.05+0.75) - 0.75 indicating Tenbora's box threshold.
Okay, the picture might be not that bleak actually, but you get the idea.
