Drops from Edacious Opo-opo who is spawned by trading multiple Pamamas or Wild Pamamas, one at a time, to the ??? at K-10 in Yhoator Jungle.
Took me 4 stacks one time. and 14 stacks another useing Pamamas. Wild Pamamas is the way to go useing as little as two or three.
soloable with most jobs 75+.
From what I saw in your tests you were told you did not do it properly. Thus you can't verify or use your data as evidence. Next time equp naban karingu before eatting the pamama's.
