Let's play an interesting RAW game. I cast Cloudkill on my targets. On the start of their turn they take damage then leave the cloud. Start of my turn the cloud moves 10 feet away from me (presumably away from the creatures who left). I then run through the cloud to the other side. I'm a 10th lvl conjuration wiz-so no break concentration, Halfling with resistance to poison saves-so minimal dmg. Or misty step by rounding half the circle through movement. Now here is the question, at the start of my next turn then does it start moving back the way it came as it 'moves away from the caster' at 10ft-potentially going toward the initial targets? RAW would seem to indicate it moves away from me, so if I go to a specific side I can make it move specific directions... All in all it does not seem very RAI, but might open up interesting battlefield control. Obviously the creatures would move as the cloud was redirected their way--a strange cat and mouse game.
As mostly a DM I wouldn't allow it, but you by-the-rules-peeps would you?
