Right now im thinking about making a Gold Wizard just wanted to see if you guys had any ideas?

http://en.wikipedia.org/wiki/Lores_of_Magic

heres the wikipedia page about warhammer lores of magic, the gold wizards are metal wizards who use the Winds of Chamon.

this would be a good place to start, it has the warhammer spell list and a good summery of what they can do to flesh out more spells.
