[@LordOfTheNight] We really should figure out what is effective against the cursed.  I suggest that consecrated ground at least slows them.  I also think that eventually Shiara will be able to create a ritual that either weakens them and makes them easier to kill, or perhaps returns them to properly dead.  Of course the ritual itself won't be a fast thing, and she'll need the others to keep her safe while she casts it -- and it will only work in a specific area, either her immediate surroundings or else an area she has to mark out in advance.
