My opinion, you're already at that level so there's no need to freeze full-time, about the monsters up there, there's nothing gonna change if you freeze .. I'm playing with the same guys since i hit Lv90, and now im Lv99, they're still the guys i face every SWB .. And the only thing i can do now is to power-up my char as much as i can .. Sacrificing magatamas, not a good idea ..

I just counted my magatama sweep for this day, and my count reached 39 magatamas .. Mixed Lv1s, Lv2s and Rainbow Magatamas Lv1 ..

Yes, Decisive Bond gives magatama but the fact that the prize boxes gives random stuff then it is not comparable for what you can get from the Ninja Exam, plus the fact that the chances of winning the battles is slim since the DB is a bit insane when it comes in matching .. And for the Redeem Shop in Space-Time, you can only redeem 3 Lv2 Magatama packs per day and that's possible if you have enough Bet Chips to buy it .. The only great source of Magatama is Ninja Exam ..
