Well, it'd also fall down if it went through the wall in most places. I'll just have to try both, I guess.

Let me propose a hypothetical for you. "The ground is shaking" trolls throw rocks and destroy a section of your floor.......

Those floors only have 1,000 health per section. Even graylings and graydwarves throwing rocks will eventually break through and I don't see an arc underneath.

That's actually something I considered. I put the barn out by the ocean, at the back of my base. Invasions should spawn on land, I think, so the barn shouldn't be in the line of fire.

Of course, it's possible this doesn't work, the barn collapses and all my boars land in the sea, but that's a risk I can afford to take. It wouldn't be too hard to get replacement boars.
