Yeah, I had the arena unlocked for a bit now, I've only just started making use of it. It is indeed a very excellent place to train. Thanks for the tip. I definitely need to spend some time in there and get used to both every character, and the battle system itself. It's also nice that they throw multiple enemies at you as my biggest problem was always dodging one, to end up beside him while his buddy was running up and ending up between them. Though I also just unlocked and equipped abilities for a lot of people to do successive dodges so now I can just hold the button and dodge like crazy (I guess?)

Either way, still really really loving the game. And I do love this battle system. I just kept treating it like a Tales of game out of instinct to start out with. Basically trying to muscle my way through fights with a constant barrage and you canNOT do that. You take way too much damage way too fast. It's also really wonky how you use items but I'm not sure there was a better way. So now there's that advantage as well (I have yet to use items in real battle or on missions x_x lol I'm such a noob)
