Thanks for the tip. I played through a few more dungeons for another roll and picked up a Horus. From what I've read, it seems to be a good starter. What do you all think?
And for the NA/JP thing, kind of expected that. Maybe I'll just stick to NA first learning how it works, then pick up a JP account once I'm used to things.
Horus is a fine starter, although he's a little tricky to use and to reach true endgame potential you have to get lucky and get a very specific set of other monsters to go with him.
If I were you I'd keep Horus, since I don't think rerolling is that necessary. Tomorrow one of the featured sets of gods is Chinese, which in my opinion are the best starters you can get for power level, ease of use, and potential value throughout every stage of the game.
So maybe keep Horus, but save all of the Magic Stones you get today to try to get a Chinese god tomorrow. Or if you want to keep rerolling, wait until tomorrow to do it.
