Some questions [Modding related]

[DominionsFan]

I am planning to make a serious mod for Dominions 3, so I have a couple of questions, because I would like to start to work on it already. I want to start to make the unit graphics. Ok here we go.

1. What is the minimum and maximum size for 1 unit's graphics tile? [Example 96x96 pixels etc.]

2. What is the transparency color?

3. Can we add new spells for the various nations? I would like to add new nation specific summons for my mod. This would be very important for me design wise.

4. Can we add new buildings? [Example: Blacksmith, which will allow the player to recruit certain types of troops.]

Ok this is all so far...
