And if you die from Shadow Strike (messed up CD) or the melee after it (late taunt from offtank) you will die with purgatory anyway because the misery debuff is too long and you cant be healed out of purgatory.
In General there are 2 Kind of Magic Debuffs. First is like Varimathras or for e.g. the first Boss in ToS or Mythic Cenarius; the Magic attack Needs to be fully absorbed by AMS to prevent the Magic Debuff.
And then there are Things like the rings from Elisande where AMS made you completely immune to the ring debuff (= Zero damage) and you could walke through the rings for the 5 second Duration of AMS.
