HM and basically anywhere u can drop white and blue q8, for purple and gold u need certain level of foe

white is practically worthless and pretty common

comlaring probabilities quantitatively is rather impossible here: for prp/gpld shields you need lvl16-20mobs, for white ones lvl20+. means usually in a given farming location you get almost exclusively either white/blues or purple/golds. on the overlap of lvl20 the odds are very distorted: lvl20 is the best chance to get a p/g max q8 among the range of possible lvls, whereas for blue/white it is the worst. and indeed you do usually get more p/g max q8s on lvl 20s than b/w. you can try to compare during regular random gameplay: usually mobs are either out of range for all max q8s in the starter/level up areas, then there is a small part of the game where you encounter lvl20s on your journey and after that the vast mahority is out for p/g q8s. also the usual community activity takes place for scs, vanqs or hm missions, so all you can expect is b/w. from that perspective you can say p/g is way rarer. on the other hand you can compare relative probability: take a lvl20mob and look at the percentage of max q8s as part of all their p/g drops - and do same on a lvl 24+ mob and see for the repartition of max q8s amongst the b/w. those are in fact comparable. then you need to respect that b/w items are subject to anti farm code and p/g are mostly not, so if you do farm at a 1kill/min rate the lvl24 you will get more max q8b/w that at same kill rate on a lvl 20 you get golds. vut increase the numbers to 1kill per sec and you would get way more p/g in comparison. maybe that helps - mayve not, but this is what I can conteibute

My experience extensively farming Wurms outside Boreal Station is consistent blue q8s. Some max value armor or dmg. Hundreds of runs never a p or g q8.
