For version 3.0.0 we've completely remade the game, which means, we also need to completely remake the powers for your blades and dojos. We will add these back into the game in upcoming updates.
I have migrated with Blades & Dojos from a version before 3.0.0
Any Blade or Dojo you've owned before the 3.0.0 will automatically be given its powers in upcoming updates.
I've earnt a new Blade or Dojo in 3.0.0
Any new Blades or Dojos you earn in the 3.0.0 update will require levelling up to level 10, and then finding the power in boxes. The powers will be available in an update newer than 3.0.0.
