#vapormancy

I was thinking, what are some strange or rather concepts of magic that aren’t very common or exist as all which is where I come across this idea. Vapormancy 

You throw potions and it forms a cloud of the same effect the potion had. Say you’re in a team of people and are all not looking so good, you pick up your healing potion and toss it by them, the effect lasts longer so long as they’re standing in the cloud of the effect that over time will fade away. An Assassin is right on the tail of his target, he sees him enter a room and decides to pick up his poison potion, tossing the glass bottle into the room and keeping the door closed, a successful kill that didn’t require getting his hands dirty. You could also apply this to concoctions like drugs or alcohol
