Choose the correct resource for Training Ground, Ability Unlock or Altar, then apply the class preset you intended.
Which material belongs to which system?
The Training Token description says: “A currency used at the Training Ground.” Its acquisition text names World Boss battles. Unlock Stone says: “A currency used for Ability Unlock.” Its acquisition text names Raids. Diamond names the Altar. These descriptions distinguish materials; they do not establish the best upgrade order or a guaranteed reward amount.
How do Growth presets work?
The September 17 update describes presets for the active Knight, Ranger or Wizard class. Configure a numbered preset in Training Ground or Ability Unlock, then select the desired number for that system in Character Info to apply it. Confirm both the active class and selected number when changing builds.
What changes as these systems level?
The developer FAQ describes higher-rank probability increasing with Training Ground and Ability Unlock levels. Exact rank percentages, costs and optimal stopping levels remain unverified. Altar enhancement is a separate Diamond-based system; its saved help text points to Passive Effects for the gained stats.
