Hero class traitstone requirements?

I can’t seem to find a list of which traitstones are needed to unlock each class trait. Is this information available yet? I have yet to unlock trait #2 on any of the classes so I have no idea what kind of slog trait #3 will be.

Thanks in advance!

They are exactly the same as legends, except all of the single colored ones require 12 arcanes on the 2nd trait instead of 10. The 3rd trait is still 6.

I see. Thank you for the answer!
