Help me make a seige mage.

[Crazy Aido]

Yes, I know, they're stupid and they don't work, but I really don't care, because I love seige warfare and this would be the best way of playing someone who can, essentially, bring a cannon to the party.

Before I start asking about stats though, could someone please explain how firing a seige weapon(specifically cannon and mortars) works.

I know I add my base attack bonus, but do I add my dex or int bonus? Can I use true strike(XD)? I just want to be sure on bits like this before I dive in.

If you're going to play a siege mage talk to your dm first. Because it's hard to siege a cave.

May I suggest reading the siege rules first?

I have done both and am still somewhat confused about the seige rules. In academic terms: Clarification needed.
