Tiamat Omega is the one summon that will up your bolts skills and you can spam Anat with her or eventually when the Wind shiva comes. MLB that asap. The more Tiamat selfies you get the better.

I am pretty sure plenty of players actually do Tiamat raids, did you send up backup quest on it? Because by the time you open it the raid is pretty much dead within seconds. By the way, I only find that you are limited to 2 Tiamat raids a day a little disappointing, but I don't get anything good from red chests anyway.

Also, they have given a lot of berries in the past. Like quite a lot if I remember that they gave out a thousand berries or so? Can't remember clearly but it was in the hundreds. I rather have crystals for more rolls than berries though.

GBF IS based on the AP/EP model mobage type games, seeing that it's from Cygames that has adapted the system from the original Cinderella Girls game and the Rage of Bahamut game. So stamina regeneration is kinda of a thing, just like in KanColle where you have resources and morale holding you back from spamming sorties over and over again.

Besides you can spam a lot coop for berries and elixirs. Join a random coop (don't join the rank 100 players and above because they might do insanely difficult EXTRA quests unless stated in the room description, resulting you getting kicked out) This doesn't waste AP/EP and you can spam them forever as long the other person is hosting the coop quests for you.

Also before the update a few weeks ago, it was 5EP and the regen was slower. Nowadays you have 10EP and it regens much faster. Just do something for a while and come back in an hour, by then your EP regen is back again.
