Null-blocked

Considered to be the worst punishment for all mages, becoming null-blocked is a complete severance of someone from all magic abilities. This punishment can only be given out by Eldrien, Spheres of the Gods, and is reserved only for mages who attempt to break Mystra's Ban, or are believed to try to attempt it in the future. Through a magical ritual, the mage's connection to magic is violently severed, and they will find themselves unable to cast or sense magic for the rest of time.
