Secondary Profession Question

Hey guys... I have a question hopefully someone may be able to clear up for me.

I have been played Prophecies on a mates account for a while now, and have just brought Nightfall, I installed NF seperate from the other account and tied Nightfall to my own e-mail addy.
So, the question is... Can my 'soon-to-be' NF characters take one of the Prophecies Skills as a secondary profession, or does it have to be a Nightfall skill... i.e Dervish / Paragon or vice versa?

Hopefully someone understands my ramblings

cheers.

Prophecies professions are otherwise known as "Core" professions, they will be available with any campaign. The only difference is you won't have access to Prophecies only skills.
So the answer is yes

awesome... I figured as much. cheers _b
