I was expecting an adventure about slaying orcs, and was initially very excited about this module. The adventure really ran it of steam after the first two sessions and the rest was a bore.
The first 2 sessions have a rough fight against some hippogriffs and crazy water shooting fish with a bridge and waterfall. There are some great moments exploring the pass and discovering its history. Then earthquakes and jumping spiders. And then a gatehouse with traps and a mechanism. This was the high point of the module and every thing after that was unfortunately down hill.
There are orcs. And then orcs, and then orcs. And not only were these orcs the same stat block and abilities as all other orcs, but the same Orc scenario was run an least 3 times with the same monsters.
I would definitely recommend the module's first half, everything else requires a lot of fixing.
