Like the World Boss that everyone has been after in Diablo 4, Strongholds are some of the harder overworld content that players can take on without any time limit in the mix. Kor Dragan is one of three Strongholds that are available to complete in Fractured Peaks and it has its own gimmick.
Strongholds each have their own tasks that players have to solve before taking on the final boss at the end. You will also have to take on hordes of tough enemies as you get there. This guide will explain how Kor Dragan works so you do not get stuck hitting immune enemies or simply dying.
Diablo 4: How to Beat Kor Dragan Stronghold
You can find Kor Dragan in the northwestern section of the Fractured Peaks, right above the Sarkova pass. This area will call for players to be at level 25 or above, but that will scale as you level up. I waited to take on this stronghold until I had full power, and it certainly makes it more manageable.
Once you are in Kor Dragan, you can climb up over the wall and begin your assault on the castle. The interior is full of Vampiric enemies and plenty of vampire knights to stop you at every corner. You will notice the main path is blocked and the Vampiric Incubator in the main hall is immune to damage. Your objective is to purge the corruption by destroying the three other incubators in the castle.

Each one of these can be found within the yellow circles on the map, and when you find them, they are fairly easy to destroy. The most dangerous part is fighting the sanguine hordes that try to defend the incubator. After all, three are destroyed, you can go back to the main hall and destroy the final Vampiric Incubator, along with Lord Decillus.
With those out of the way, you can descend down the main hallway into the final boss room. If you go up against Nilcar, Forgotten Bishop, the fight is fairly simple. Each time he loses enough health, one of the three incubators in the room will open up and you will need to take out an additional enemy. Continue to kill these as you burn the boss and victory will be yours in Diablo 4.
