2 Class Specialties?

[Draxis]

I know the description on some of the class specialty enhancements states you can only have one.
However, is this one per class, or one per character?

For instance, are tempest warchanters possible? Or tempest assasins? Etc.

I'd rather find out now than 12 levels down the road.

You can only have one class specialty per class, but you can have multiple specialties from different classes. So yes, a Tempest/Warchanter is possible.
