It seems like there IS NO OTHER ITEM

Sandsheel gives us the final, enthraller-killing-holy-weapon, or Willow potentially gives us nothing.
We NEED that item, because otherwise we wont have the 7th holy weapon, and we wont be able to kill the 7th stalker.

Are you really willing to bet the safety of everyones souls on the law enforcement strategy of a post apocalyptic town?
