The Worldstone Keep is the last building, protected by three Ancients , where Baal is. The entrance is sealed until those Ancients are defeated.
The most fearsome Oblivion Knights can be found there at Nightmare Difficulty and Hell Difficulty .
It is also one of the area level 85 zones on Hell added in patch 1.10, meaning the monsters there have a chance of dropping high level items compared to other places - however, due to the Willowisps and Oblivion Knights it might not be the easiest place to do Magic Find runs.
