The Sanctuary aura

I know about it being bugged and whatnot, but I don't know how the "ignores physical resist" part works. What exactly does it do to the undead's physical resist? Does it sum with amp and decrip? Does it work only for the carrier of the aura? (seems to be the case as my merc kills decripified ghosts very slowly)|||It makes the carrier of the aura ignore the physical resist (meaning it will be considered 0) of an undead monster if the physical resist is positive. This comes after the effects of curses.|||Thanks
