>>39816033Rolling costs 300 gems. You get 30 gems every time you complete a battle for the first time (you can repeat battles to grind for items but won't get gems again). You get 10 gems every time you watch a story cutscene or sync pair story for the first time. After you scrape the very bottom of the barrel in content, you have to start relying on login bonuses. Every week has 100 free gems on the first and fifth day, and 50 free gems on the third day. You can also do daily missions to get another 30 gems a day, for a total of 460 gems per week after you run out of content (3 rolls in 2 weeks).
Uh, and completing some achievements give you 10 gems. Achievements are usually "Obtain X amount of Y", and every time you complete one, it comes up again but with a higher requirement (they do have final totals though so the gems are finite).
Oh yeah, and every day has a daily discount where you can use 100 PAID gems to do one roll.
Let me phrase it this way. There are 65 characters in the game at launch. While you'll get 23 through the story, the other 42 must be rolled. When the game launches, people will be around their 30th roll, and that's assuming they're dedicated and played since it came out in Singapore. With the 10 additional rolls in log-in bonuses in the next 7 weeks along with the new content with the update, it'll be possible to hit 42+ rolls by the end, though it'll probably be sub-50. But you're far more likely to begin rolling duplicate characters rather than always rolling a new one, so yeah.
