Spent 99% of the run trying to figure out how to unlock our SJs here. Turns out it's not a ??? that triggers it like in Bubu. You need to kill the 3 red Nightmare Flies to unlock your SJs. One is near the west oasis and has a massive link with Hippogryphs. One just to the SE of the outpost which links with Manticores. The last one is a little farther to the East and links with Sheep. We were able to pull the sheep one without links so I'm sure it's possible to do the same with others, just need to figure out how. Managed to kill the last fly with 30 seconds left and bam- "SJ Restriction wears off."

I honestly don't know why people like the above posters even post here. You guys just bragging or something? If you don't wanna tell how, then just GTFO. Truth is, people will find out eventually, there is no point in acting like you're hot shit and with-holding info.
People did that with Sea NMs. That was quite beneficial, eh?
