Different Masteries need different unlocking. Some require additional Carbo and/or Stoney Cores for every next Level (for example the whole tree with Deep Wounds, each level needs more Cores).
But once each level is unlocked, and if you Reset your mastery later, they will remain unlocked (except for needing minor amount of either Units or Gold each time).

Can anyone suggest me a great mastery?
