With 574 perception, I get 500+ always using disc+methx3 then gather. I have gotten 3 dusks, 2 dawns, and 1 landborne at a time on these. Pretty much I just go grab the 4am/pm nodes node right after I finish my culprite grab for that set. I then go back to crafting and do it again in 30 minutes. I used to try getting multiple, but when I got two dawn from a 7/8 rarity I just stuck with grabbing one good one each time.
