Do spores/thornheart bypass save vs. spell resists?

In my expeirnce I'd have to say No. Thornheart is one of the easiest to resist, but what it saves against I don't know. Spores is a little harder to resist, so I'm thinking it's probably going through save vs spell since almost everyone neglects this, especially damn roll hungry warriors. I might find the log where someone saved vs thornheart 12 times in a row if I dig through my Grecken stuff.
