Phadnelver and Below: The Shattered Obelisk (Part 3c Cragmaw Castle)

Welcome to the next installment of the PaB: The Shattered Obelisk series. In this session, your players will find themselves at Cragmaw Castle where they will have to battle through a castle filled with goblins in order to reach the missing Gundren. I've made a few minor changes to the original to make it a more engaging encounter. The main one is altering the final encounter to use the mechanics from Flee Mortals! This change allows the final boss battle to be far more interesting and challenging; as well as have your characters feel like absolute badasses as they tear through hoards of minions.

I've included the Preview PDF in the Complete Collection in case you need to refer to it; the encounter pdf should have most of the information you need though. Lastly in the event that Gundren meets his untimely demise, remember that Reidoth also knows the location of Wave Echo Cave, where your players will soon reach the conclusion of this epic adventure!
