Confused

[RiversideGuy]

UPDATE: So I was looking at my maps and saw this FATE HAD commenced, so I high tailed it there. Of course, by the time I got to the spot, I saw a Failed message, so I sat to wait. Gave up after waiting over 20 mins... it went from daylight to deepest night.

Like I said VERY bad design... so easily solved by putting a NPC in there to trigger it. As it HAS been an issue for 3 years, doubtful it will really get addressd, shame.

That particular one requires you to defeat a mini-boss in a FATE, which is a bit tricky to do by yourself unfortunately.

You can just summon your Chocobo for the extra boost needed to win, especially if you made a heal based chocobo.

You waited 20 min... You do know that the Book Fates for the Animus upgrade could easily have you waiting 4-6 hours, right? God forbid you fail the FATE and have to wait again. The way how you have to do this is to constantly check your map for when it spawns while doing the other non-FATE beast dailies and then rush over to complete it when you see it go up. It seriously only requires 30 min max in order for it to respawn, and you can stockpile the items you get from it even if you don't have the quest.
