Do I understand correctly that farming a cube means you spend a blue cube to fight a boss, and then one cube it, and get a blue cube back as a reward? If so, then you only gain a cube when using your naturally regenerating cubes to engage the boss, right? So the only other way you'd gain more cubes than you spend is when you find "???" level bosses, right? Are there other ways?
