I didnt' really know you could unwhisper, or unwhisper back.

But TeacherCreature's solution makes sence to me, but I think we're both waiting for him to tell us how to do it 

ah cool thoguht so by guessing which means your solution works good enough.

I didnt do anytign special I jsut made an invisible serpent ward but in the est_effect section made it so noone could see it there for it seems liek the smoke is doign the damage
than I added a cool coughing sound per tick of dmg and timed the serpent ward to match the smoke duraiton
