This adventure was a great tie together from mines of Phandelver and Princes if the Apocalypse. My playe3rs enjoyed it, the layoutb was straight forward, and it was easy to run.
I just finished running this for my regular group and they really liked it. It was run pretty much as written though the party didn't stick with the linear path as written. I also through in a nice encounter back down the mountain with a Hill Giant leading a small pack of Ogres as a surprise for good measure. They are excited to get back to Phandalin and see where there next adventure takes them. Southcrypt Falls? Maybe. They won't know until they talk to Gundren again.
I cut the first part of the adventure and changed some of the monsters, but kept the core concept and layout of the adventure. This is a great way to tie the Lost Mine Of Phandelver adventure in the Starter Set with other adventures (in my case Princes Of The Apocalypse)
