Yep full raid gear or one exotic plus rest of raid gear. Here is something else about that. I'm not 100% on it but I'm pretty sure that you can't get the helmet unless you do the raid on hard. so best bet is to get an exotic helmet and the rest of the raid gear. But like I said i'm not 100% about the helmet. Thats just some stuff i've heard around it could be completely wrong. Hopefully someone with more knowledge will be able to confirm that.
