I have tried and tried to find information on what skills and how high of skill is needed to make the towers and personal towers. please direct me on where i can find the information...i have yet to be able to buy NW in my area (stores all say sorry we dont carry that game refering to AO).

Also anyone know if in the future the darn thing could be downloaded like how i got AO in the first place...i hear its only a key and a few voice things anyway.
