What makes LB unkillable?

[Ezric]

Using Exult Studio with FoV, I'm having trouble figuring out what makes Batlin and Lord British invulnerable to attacks. I'm sure I'm overlooking something, of course, but it's eating at me that I don't know the "how" of it. Can someone possibly enlighten me?

Thanks

With Exult Studio open, go to 'shapes.vga" (left hand tree) and find the corresponding shape (you can find by name, or look at the shape indicated by the NPC's data). Double-click the shape and go to the 'Monster' tab; in the 'Immunities' group, 'Death' should be checked (note that being immune to 'death' implies being immune to 'death magic' -- e.g., death bolt).
