Two things--
First: why doesn't the plague cause undead to spawn? The original did. I debated making it do so in my game. But that just might be the straw that broke the cities back. Swarms of plagued rats and crows would be bad, add ghouls and things get super bad.
Second: My PCs are going to do doing the boat soon. They want to enlist the help of the crazy druids protesting the The Turtle & Pesh (in the guide to Korvosa). They seem adamant there should be at least one druid who could shape change and scout for them. I am leaning towards a group of low level druids with nothing better to do.
I mean I -could- make one a shape shifter who goes and scouts... and never returns. The hag would tear them to shreds.
Any thoughts?
