Need advice about a buddy key

hi everyone,

I finally got my brother back into playing GW with me, and he only has prophecies. I have a couple of keys for him to use to try out Fact. and NF,. but he has asked me a question that I can't find the answer to.

Will he be able to get a set of fact. and NF armour and be able to keep it, until he is able to purchase the two campaigns?

I am willing to help him get the ones he wants,. but we just want to make sure that he can keep the armours until he can buy the two additional campaigns.

any help from you guys would be greatly appreciated.

Thanks

Vizzi

Im not really sure but maybe it is like the skills. When the trial expires they get locked. Like when you go into RA with sunspear rebirth:P
Not sure about armor though.
