I have to admit that the last page of the IC is WAY too busy for me to do much anything. I mean, most of it if 1 or 2 rounds too early.
First, everyone but Rezzik is in the fog so you have a 20% or even 50% miss chance, unless you have blindsight. Even then, you have to be near the opponent to attack. Dez is 20 feet away from S, and has a 50% miss chance.
I agree with Venn that everyone's doing everything too fast. Some of it will have to be revised unless everyone's using a belt of battle and swift teleportation.
Alenatorion is in the map now. You will have to make a Fort save as well since you're in the cloud. You had to be that close to not be in the way of the table, and for everyone to come in. Not to mention you saw the dwarf had been moved.
And yes I was lazy about the Initiative and everyone's colours.
If Rezzik moved just north of Melkior, he will have an AoO taken on him by the invisible demon there. I see that Dez has See Invisibility, but does Dez?
