Very sorry to hear about your mom, Digger. As the others said, we understand and will make do.
On another note, if you 6 that are playing in the next adventure would let me know when you are approved here in this thread while I'm prepping to start the next thread, I'd appreciate it. Of course we had at least 1 that was going to start playing while unapproved I believe. That's fine as well and I'm not trying to wait on all to be approved before starting. I'm drawing out my maps for the next adventure so that it's all good to go.
As Digger said, the dragon had double moved and was out of the cloud of darkness while at range 14 from the party. All you needed was enough ranged stuff that could reach her. I think Quagmire's sling was the only thing that would reach. Eldritch Blast stopped at 10, Hrav's shuriken stopped at 10 or 12, etc. As I understand it at least, the cloud of darkness stays stationary once created and she can mantain it or not, but not move it.
