We have a bit of a mess. Everyone attacked the same Worg as the fog would obscure. That seems off to me, so I'm gonna play fast-and-loose with your targeting. I'll make all the long-range attacks go to the further away Worg and the close-range ones go to the closer one. This will give the closer one a chance to attack, which I suppose you probably meant to avoid, but the fog cloud is best where it also obscures the route to the camp, to keep the gnolls from noticing their guards go down. Trust me, this will work as intended, if not 100% as you meant for it to go down.
