Posts from Class Auto-translated

I recently started playing and haven't heard anything about Light or Darkness yet... I understand that later I'll need to complete a quest to check compatibility with Light/Darkness. My question is: can I choose a profession for my Monk (for example) that is offered to me without any Light/Darkness requirement, like "Enlightened," and then later upgrade him to Ninja? Or is the Light quest required for that? P.S. The same question applies to the Knight... can I upgrade him to Crusader so that I can later make him a Dark Knight?

Each class has three tiers:
1) Basic, which is the starting class, and you don't even need to acquire it.
2) Advanced, such as various Crusaders. To get this, you need to complete a quest. This, of course, gives certain advantages, such as new skills to learn, increased health, and mana.
3) Dark/Light. To get this, you need to complete a quest for the advanced class and choose to side with darkness or light (later in the story, messengers will come from Bracada and Deyia; I think it's clear who represents light and who represents darkness). After that, you can take a quest from the trainers to become, for example, a Black Knight. This again gives new advantages and access to new skills (for example, a sorcerer who becomes a Lich can learn dark magic, as can a Dark Priest).

Thank you for your answer :)
I have a few more questions:
1) Is there only one advanced class for each character? Will it affect the third class?
2) There are also quests, for example, for a Druid... although I don't have one in my team... can these quests still be completed, but the profession won't increase? Or can they not be completed?

1) No, there is only one class. As a rule, the trainer will later give a quest for the Light or Dark class (it depends on the trainer). If not, you will have to find a trainer for the desired class. 2) It gives experience and records it in the diary, but otherwise, it doesn't have any effect.
