If you haven’t put two and two together yet, Macca is the demonic currency in SMT: Devil Survivor 2 Record Breaker, and a vital resource for becoming the high bidder in Demon Auctions. The entire concept of being able to pick up deadly monsters from eBay-style auctions may terrify you, but trust me, you’ll be doing it a lot. See, unlike SMTIV or Persona Q, the only way to get new demons is by buying them or fusing them. And you can only fuse so many before you run out. But no problem, just crack open the demon auction app and get yourself a whole new complement of demons!
Each demon will come with ratings – the more stars the better stats and skills it comes with, meaning a strong ally for immediate use, or eventual fusion fodder down the road. There’s also special auctions for exceptional demons, but make sure that you have enough Macca on hand so you don’t get outbid by that jerk Carol J (or any other bidders).
