Hello Ya'll
i made a fresh farming char not to long ago, and ofcourse it requires tailoring, so when i hit max tailoring i went farming.
i usually first rack up a hundred or so corpses before looting, and when i did, i noticed there were multiple recipes for celestial cloth in the Corpse:

you can only carry 1 at a time, so i learned it, and found out i could pick up another, but not only that, i could also learn it again!.. and it gave me a New Epic recipe!

TLDR: Get tailoring max, rack up a bunch of corpses untill there are 4+ recipes in there, the learn > loot > learn > loot >learn> loot . . .. . .. ..
