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.

In TenkaiClassOnline you never pick a class from a list. You become one by playing.

You act. Fighting, exploring, training and finishing quests all count as progression.
Your attributes grow. Each activity trains a mix of attributes, so a character who fights grows differently from one who studies or sneaks.
Classes open up. When your attributes meet a class’s requirements, you start working toward unlocking it.
Your main class follows you. Your main class is always the unlocked class closest to what your character has become.
You level up and specialize. Experience raises your level, which gives you attribute points to spend and mastery slots for the classes you want to deepen.

Everything feeds everything else: the way you play today decides which doors open tomorrow.

In this section

How attributes grow: what trains your character, and why the same attribute gets harder to push.
Classes and your main class: requirements, unlocking, and how your main class is decided.
Levels and attribute points: your character level and the points you spend directly.
Mastery: going deeper in the classes you’ve unlocked, and where abilities come from.
