Quick Mod Questions

[Stavetor]

Hey all,

I've been poking through a lot of different mods lately, trying to learn how everything's done, and I think that I have a pretty good grip on things, but still a few little chunks of code elude me. They aren't mentioned in the mod guide, any other mods that I've seen, or in any of the threads I've combed through. My questions:

1. With the #flyspr command, what's the sprite number for a Jotunheim-style hurled boulder?
2. How do you make a weapon 2-handed?
3. What's the code to give a unit a siege bonus? I tried #siegebonus, but it didn't seem to work.

Any help will be greatly appreciated, TIA.
