How progression works
No class selection screen: what you do grows your attributes, your attributes open classes, and the classes you invest in grow their own mastery.
Attributes
The attributes that describe your character: what they are, how they shape your classes and your fighting, and how they're grouped.
30 attribute pages
Items
Every item that exists in the game today, grouped by kind. Bonuses apply while an item is equipped.

Development notes
The technical side of TenkaiClassOnline: how it's built, the full progression model with its formulas, combat stat weights and the event catalog.
