tl;dr You need the dummy account so that you have a means of logging out of the game. Without syncing your game to something, you can't manipulate the save at all on a single device afaik.
You're welcome, and don't sweat it. I explained how. I didn't explain why.
Lets assume you've connected the account you currently have(With bad units) to a dummy facebook account. Now you want to reroll.
You log out of the game via the menu, which lets you start over. No problem.
When you pull units on this new game, and they're garbage, you need a way to erase the data This is where the dummy fb account comes in. You go into the menu, and reconnect to fb, and you're new game(The 2nd one you made), will be overwritten by whatever was saved to your dummy facebook.
Now log out again, and repeat.
Once you get favorable units, which imo are at minimum Luneth and Refia for this banner, exit ffbe, and log onto the facebook app. There you will log into your actual facebook account. Reload ffbe, and connect the account you want to your real facebook account and you're good to go.
You can do this on one device, with one dummy fb account. This is how I did it when I started and unless this new update changes something, it should work for you as well.
Glad you got it working, Alvhino. I'm happy to help.
For macro users, Nox works again. There is much rejoicing! Nox runs so much more smoothly than Memu on my Surface.
Omg every quest has the 50 Lapis first time completion. Story quests, Vortex including reborn bosses... exploration quests. I'm going to be dumping so much stamina redoing the story for this Lapis.
I was not expecting every quest lol.
Is there a way to lock parties so one can have summons and another cannot (for arena, Diabolos has a no-no ability).
You can enter the arena fights with the restricted abilities. You just can't use them during the fight, they will be unselectable.
Yep, I'm just looking forward to the update that JP has where you can set espers per party. I want Diabolos most of the time but right now I'm farming explorations... XD
How the hell are you supposed to win against whales in the arena lol.
Edit: i've lost every fight so far, is there any prizes for participating at least?
My melee characters are agriad, vaan, locke, zidane. I only have charlotte as a tank. I have a kefka, tellah and golbez as nukers and I have a lenna healer.
Edit: also i have 0 TM items or abilities.
I use an under lvled Ramza, Agrias, WoL, Lenna and Kefka and haven't had a problem yet. Status attacks are your friend and kill the healer first.
Also, just managed to pull a Vaan...is he still worth upgrading if I already have two other Full Breakers and another unit with Focus?
Hot diggity! Summoned a bunch in an attempt for Refia and lucked out with a Luneth!

Lost nearly the whole day to extended maintenance and a dentist appointment that involved meds that knocked me out for 8 hours.Arena is pretty fun but frame rate issues seem to creep in after a bit. The prevalence of 6* Cecil and using 4 Excaliburs in my team is not making it fun to kill him lol.
If Arena's taught me anything, it's that everyone else has Luneth and/or Lightning.![]()
