Update this and maybe split each world quest like a chasm, enkanomiya section and split the quests by their separate islands and also do the limited quests but in a limited section. Golden apple archipelago can have its own separate section dividing the differing versions (1.6 and 2.8)

For the seventh samurai as the part of inazuma world quest i believe you have to finish tatara tales first, then you go to the island to the east of inazuma castle, notrh part of the coast specifically. You'll need to talk to xavier

About Equivalent Exchange, it's a side quest given by a Fatui guy in the Church. Idk about any sorta pre-requisite but I DID do a Daily comm. given by the same guy so, maybe that is it?

Windrise, Windfall is a world quest you can unlock by talking to Elzer in Dawn Winery if I remember correctly.
