What does the threshold effect of Infinite Vitality protect against?
What does the threshold effect of Infinite Vitality protect against?
Anything that would Damage or Destroy Dahan in that land, whether Powers, invader Ravages, Events, etc.
It does not protect against effects that "remove" or "replace" the Dahan.
If the threshold effect of Cast Down into the Briny Deep is used, the Dahan can survive. They would then be moved to the nearest legal land (as per anytime an Invader/Dahan piece is left in an illegal place).
