Spells cast on other creatures, objects, or locations (not on the character) are vulnerable to dispel magic as normal.
The DM may allow other selected spells to be made permanent. Researching this possible application of a spell costs as much time and money as independently researching the selected spell. If the DM has already determined that the application is not possible, the research automatically fails. Note that the character never learns what is possible except by the success or failure of the character's research.
