Hey, please don't post the same thread in multiple forums. Thanks!
TLR didn't die from relying on nicrosil. He died because he'd been compounding atium for a thousand years, and when Vin pushed his atiumminds away, those years caught up to him.
A Fullborn can compound Fortune just like any other attribute. So he would never run out of Fortune, just like he'd never run out of speed or strength or healing. We haven't seen any evidence that points to the Spiritual attributes not being compoundable.
Actually, it was Pushed out.
Sorry, I don't think your theory holds water here.
Also, per the site rules, it'd be really helpful for reading your posts if you would use full words and punctuation as well as good paragraph breaks.
