Spent 89 stones on the special banner so far pulling for green. I've had horrifically bad luck so far. Only pulled a single five-star, a dupe Hector, which is the one I wanted the least (but still pretty good). I've seen an almost impossibly low number of green orbs, with almost 50% of screens not even having one, only a single screen having two, and none having more than that.
Oh well, banner's up for a few more days and there are tons of stones on the table, so my luck will probably flip. Kind of really want another SCamilla and a Brave Ike, gonna be really disappointed if I don't pull at least one.
Haven't had time to look at the weapon refinery yet, but that's going to be all kinds of interesting.
