I would like to aim for Fire Mastery but I've bought the armor skill in Cold. What are the requirements for Master?

Is there a build around here for the Pure Fire Sorcerer? Can a Fire Master get the Hydra spell? Enchant?

I'd like to know what stats to build and how much to build each fire skill. Is Fire Mastery a good way to go?

There are so many things to learn in this game. People talk about PvP vs PvM. Synergy. Huh? I know what the word means but not in the limited sense it seems to be used for this game.

And I haven't even gotten close to finding anything in the game related to magic find. I just know I need 6 pure topaz gems and helm and armor with three sockets each. Where do I find these? I'm on the third quest (Cain) now. Hope I do it soon. The game is just boring if all I do is go out and fight and bring back junk to sell. I need to see some good stuff soon.
