Secret Manuals and the Breakthrough System
Character power in Justice Online is tied closely to Secret Manuals, which require a breakthrough every 10 levels to keep advancing. Each breakthrough needs Secret Manual Fragments, obtainable from the "Wanli" quest and general treasure hunting — budgeting time for fragment collection alongside normal leveling avoids getting stuck at a breakthrough wall.
The Personal Transmission Master-Apprentice System
Players above a certain level can't become formal regular apprentices to other players, but they can still form a "Personal Transmission" master-apprentice relationship. This system exists to satisfy the wuxia-genre desire to take on a master figure even at higher levels, and can provide guidance and social connection that pure solo leveling misses.
Sworn Siblings for Social Progression
Like-minded players can become sworn siblings in Justice Online, pledging deep friendship in a system that reflects the game's wuxia roots. While this is primarily a social feature, strong social bonds in a heavily group-oriented game like Justice Online translate into more consistent access to instance groups and shared progression support.
Instance Types Serve Different Progression Needs
Since instances are split into Guild, Experience, Equipment, and Currency categories, efficient leveling means running Experience Instances specifically when your goal is character level progress — Divine Marquis Order, Wanxiang Tower, Fallen Maple Manor, and Qingming Riverside are commonly cited as the core Experience Instance rotation.
Choosing a Class Early
Justice Online offers multiple classes drawing from wuxia archetypes, and while the specific roster has expanded across the game's many expansions since 2018, picking a class that matches your preferred combat style early avoids a costly or time-consuming reroll later, since class-specific systems (skills, Secret Manuals) are built around your choice from the start.
Paid Leveling Services
Power-leveling services exist for Justice Online as with most MMOs. Weigh the time saved against the account-action risk covered in our safety guide before deciding.
