Limit of Skill Trees?

[Dragon]

Are there a limit? I want to learn everything, but I cannot learn Dark Arcana. Or, if I learn Light Arcana, I cannot learn Dark one?

[Zhon]

I've only played with Master Arcana characters as of now, and they can learn 3 different arcanas from trainers and at least 1 skill tree from some heroes like Riq, Astrid or Tiqin (dunno if more than one as I didn't try). I still don't know if Gifted or non-magical playable characters can learn less or the same quantity.

So, no, you can't learn everything with the same character
