Gacha Exchange is another method of getting new S-class characters and Eidos by exchanging Gacha Points. Every time you do a Gacha Kick, you’ll get 15 Gacha Points. When you have accumulated enough points, you can use this method to buy an S-class character or Eidos. Characters cost 3600 gacha points while Eidos costs 1800. The only downside to this method is that the available characters and eidos are very limited. The pool is refreshed every Monday at 12:00.
