I've created a custom spell to tear down the wall, and visually, it works. I want the NPC to cast the spell several times before the wall explodes, with small bits coming off each time, (like they're chipping away at it). I played around with visual effects a little, but I don't want to get more in depth until I figure out how to make the wall bits fly.
I've got this vague idea that I would have to write a separate script for every tiny piece of debris, but I really don't want to do that. It would be easier, I suppose, if I wanted to work with Havok items, but the only Havok rocks I can find are part of the rockfall trap, and I can't figure out how to use them in a way that looks right. Any pointers ("use this script command, use that static, look at that quest scene") would be helpful as I am totally at sea here.
Thanks for looking!
