Thanks @wdzepplin

Looks like I just need more rng (welp there go my chances of ever seeing both those bosses).

Another question:
Is cows still the best place to farm blue orgs? I've seen people have like 10 sets of them but no idea how do they farm that.
And did the chance of alkor head dropping get lowered? Last patch it didnt take long at all but now I'm at 80+ swampy pit runs (with around half of them being full runs) and it still hasn't dropped.
