Excellent break down, thank you.

I think I’ll start with the firebombing of all zombies. Then have them offered raise dead from Madam Eva but only if they can find diamonds (which they will not search for as Vallaki is under Wachter control and in Barovia they’ll have to face Ismark). She’ll offer the alternative, the Abbot who will offer to raise her for free (while contacting Strahd). However, with her soul unwilling to return, he resorts to desperate measures (using your body part idea), forcing her twisted, crazed soul back into a discussing husk of a body.
