How to unlock new classes in Skyforge
Skyforge's class system is definitely something different, and new players starting the game will be met with three classes to choose from. This can be a bit of a shock, considering the number of classes shown on the official site.
New classes are unlocked as you progress your character using the Ascension Atlas, the primary method of improving your overall character Prestige (essentially level) and stats.
There are two tiers to the Ascension Atlas, one of which you unlock after progressing far enough into your first class.
This is either called "Path of the Cryomancer," "Path of the Lightbinder," or "Path of the Paladin" depending on your current starting class.
Once you reach and unlock this point in your first class's progression, you will unlock the upper tier of the Ascension Atlas. If you thought customization wasn't actually all that vast based on the first Atlas tier, you're in for a treat upon unlocking the higher tier.
The stats and skills obtained here affect your character no matter the class you're using, meaning these are permanent improvements. This is also where you unlock new classes after a great deal of effort.
If you zoom out, you can clearly see which nodes are for unlocking classes.
You must work your way from your starting class's nodes out to one for a new class, and ultimately work your way all the way into a middle of that class's node to unlock it.
You should go into the game with an idea as to which class you really want to start with, and which classes you want to go for first. Some take much longer than others to branch out to, so plan your progression properly to avoid wasting Sparks. You only get a certain amount per week!
You can have the Ascension Atlas automatically plan out your course to a new class by right clicking on a class node and clicking on "Find Path".
This way you don't have to memorize the path you need to go.
I hope this has cleared up any confusion there might be on how classes are unlocked in Skyforge. The game requires some planning for your character's future, so take the time to think about what you want to do in the long term.
The game does allow you to try out every class not too far in. If you're not sure what to aim for, wait for the Training Room to open fully to start planning based on the classes you find most fun.
