Wishnapping is a whole entire other class of threat. Almost nobody besides Abrogail Thrune needs to worry about it. It's just too expensive.
If you are Abrogail Thrune, or somebody else worth more than a hundred thousand gold pieces to kidnap, the first elementary precaution is to be Mind Blanked whenever you're out of a Forbiddance.
But as for a Mage's Disjunction or a Nefreti Clepati Dispel being levied on a Forbiddance, while you're inside it, and a Wish following immediately after -
Well, then, if you're Abrogail Thrune, you laugh. Involuntary Wish-movement allows both Will-saves and Spell Resistance, and Abrogail Thrune wearing the Crown has plenty of both. Even without the Crown an 8th-circle sorcerer still gets a heck of a Will save, and Abrogail Thrune's luxuriously spoiled aristocratic upbringing has granted her something of an extra-strong Will save on top of that. A circle of a hundred noble Efreet could all Wish for her to be moved, one after another, and Abrogail Thrune would not move did she choose to stay; the Efreet are not such mighty casters, after all, even if they have a strange affinity for Wishes. You'd have to render her unconscious outside a Forbiddance and take off her Crown, and if you can do either of those things, you can just take the Crown.
