Cool, exactly in line with what I was thinking/hoping!well, as soon as they move into the fog (which takes up 15X15 feet of a 20X25 foot room), it will go away.
The Large chef is only 5 feet from the fog and the little chef is 10 feet from the fog. They haven't noticed anything yet because their backs are turned.
Chances are, their first attack with be at disadvantage as they move into the fog but after that, it won't be useful.
Anyone shooting from the cover of the fog will get advantage until the zombies realize it's not real. Anyone moving out of the fog and attacking in melee will get advantage on their first attack, if they made their sneak check.
