Secondary jobs

Now that i have a secondary job, i cant access the skills to that job. for some reason, now that my skill bar is full, i cant drag another skill down to it, and i cant use any from the skill list itself. Whats wrong here? Is there something else i have to do to use it?

In order to change skills around, you have to be in a town or outpost. In the tutorial, as you collect more skills, you'll get more than you can fit on your skill bar. In order to change around your skills, you'll need to go to one of the towns: Ascalon City, Ashford Abbey, Fort Ranik, Barradin's Manor, Foible's Fair, or any of the other dots that you can see on the map that I've forgotten about.

I also have another question. As to create new armor, you have to be in new ascalon, but what drops the items to make new armor?

That depends completely on your class. If you are a warrior, for example, you need mostly Iron. Not to mention, you are in luck as you can use the salvage kit on any item and most of them are made of metal! (Of course, when it comes to steel, it's another story).

Hmm, what about bolts of cloth, and hides? What would drop those, or at least the items to salvage to make those?

Mostly salvagable armours and garbs. Try hunting Charrs.
