Yeah. Well actually, I don't know for sure, because I never got to see Terra Break when I had 255 Vit.. but there was a thread discussing Omega on a different forum, and everyone claimed Terra Break ignored Vit. But you're welcome to try it out to make sure if it does or not
And yeah, I know about getting the stat boost items. But I couldn't really be bothered heh. I think I'm too lazy to do all that
