  • Core Units are always a must pull, as they provide you with more options for building different teams and lineups
  • Don’t really need to invest much into core units, so it’s relatively cheap to build
  • Has the option to go for DPS or HP build
  • This core only requires 2 Espers, 1 Grappler and 1 Duelist. So there’s more flexibility in terms of lineup
