I don't really understand why. It was showing on my other characters and I made a new character so I can level it up using the limited quest. At first, I thought it was just some sort of level requirement but as soon as I hit level 50, the limited quest is still not showing so I checked my other characters and saw the limited quest's lowest level requirement is level 8 so I do not really understand why it is not showing up in my new character.
Are all of your characters on Episode 5? Check in Quest Counter > Change Settings > Switch Episodes on every one of them.
@RemiliaScarletX newly created characters always have to start from scratch, it's common to most games that have a create character feature
@coldreactive Funny that I accidentally signed in on my Microsoft account instead of my Steam but yes, all my character are at Episode 5.
The JP counterpart of this quest requires to clear ARKS quest "Suppress Za'udan" (the very first ARKS quest) as a prerequisite, but I'm not sure if this holds true in the global server too.
