Reign of the Black King Diablo III Guide

Last update: 11 May 2016

This quest can be unlocked by talking to Deckard Cain.

Use the New Tristram waypoint to return to the Cathedral Garden

As mentioned in the description, use a waypoint to travel to the Cathedral Garden.

Enter Leoric's Passage

You must choose the same path as the one you've used after you've rescued Deckard Cain. Proceed to the passageway leading to Leoric's Passage (you're travelling to the place where you've first met Cain).

Go to the Cathedral Level 2 through the ornate door

Go to the place where you've found Cain earlier in the game. Proceed to your right, descend the stairs, open the golden door and enter the new area.

Descend through the Cathedral

You're standing in Cathedral Level 2. This is a rather large area that's populated by plenty of monsters. Watch out for Tomb Guardians, because they can summon Skeletons.

Your objective is to find a passageway leading to the next level of the cathedral. Once you use it you'll find yourself in Cathedral Level 3. Head left here.

Give aid to the Warrior

You will encounter a group of Necromantic Minions here and you'll notice that they're using magic to hold a warrior in prison. Kill them all and also deal with other monsters present in the area. Once you've saved the warrior talk to him.

Find the warrior's stolen items

Use the stairs to head up and search the nearby chambers. Your current objective is located directly in front of you and there are some monsters in your way.

Dark Cultists are guarding the chest with stolen items. Kill them and then open the chest so that the warrior can reclaim his things. The Templar will join you and you'll also find a waypoint nearby.

Find and kill Jondar

Head forward, travelling through corridors and using stairs along the way. You will soon find a door that's protected by black magic, but thankfully your new companion will deal with this problem. Head down and it shouldn't take long for you to reach Jondar's hideout.

Jondar can summon Skeletons and he is also capable of firing projectiles that inflict poison damage. You should also notice that he's incredibly fast. Once you've defeated him your companion will finish him off.

Join the Templar

You will now have to decide whether you want the templar to continue following you or not. It's highly recommended that you agree to his offer. Once he's a member of your team open his character panel - it's used to change his equipment and to activate his skills.

Search for the Royal Crypts

Descend the stairs and use the passageway leading to Cathedral Level 4.

This location is huge and it contains a lot of corridors and chambers. You will encounter monsters that you already know as well as some new types of creatures. Skeletal Shieldbearers are equipped with shields and they can use them to defend themselves against your attacks. Skeletal Archers are equipped with bows and they can become a threat if they operate as a large group. Don't forget about killing the Tomb Guardians as soon as possible in order to prevent them from summoning too many Skeletons. Your objective here is to locate a passageway leading to the Royal Crypts.

Find the Crypt of the Skeleton King

We're almost there. Choose the only available corridor, defeat a new group Skeletons and locate a waypoint. Approach Leoric's sword to witness a retrospection of the king's death. You may proceed forward.

You'll meet Skeleton King here once again. Notice four Activated Pillars that are responsible for summoning Skeletons to the battlefield. You must destroy them, but be careful, because you'll be dealing with dozens of Skeletons. In addition to that you'll find yourself under fire from the Skeletal Archers. Keep fighting until you've destroyed the pillars and then follow the Skeleton King to the next area.

Keep heading forward until you've located a passageway leading to the Crypt of the Skeleton King.

Enter the Crypt of the Skeleton King

Choose the passageway to find your way to the Crypt of the Skeleton King. You'll witness a cut-scene here showing the Skeleton King.

Kill the Returned

Proceed to your right. The king will close the gate and send a group of the Returned after you. The monsters you're fighting are stronger versions of skeletons. Once they're gone the gate will open again.

Place Leoric's crown on the Skeleton King

Head up the stairs and approach the throne where the king's body can be found. Place the crown on his head, bringing him back to life and starting a boss battle.

Kill the Skeleton King

The Skeleton King is constantly summoning the Returned (stronger skeletons) and the Forgotten Soldiers (skeletons with shields). He can teleport himself across the battlefield and he has a lot of health points. You should also know that thanks to his long weapon he can attack you from a larger distance. When you're attacking him you should focus on killing the summoned creatures quickly, so that you'll have a chance to injure the king before he can call more monsters for help. If the creatures he's summoned aren't standing in your way you can also use the opportunity to approach him right away before he teleports to another location.

Enter the Desolate Chamber

Once you've killed the king enter the chamber located underneath the throne.

Talk to the Stranger in the Desolate Chamber

You've reached the point of impact. Descend to the crater to find Stranger. You must talk to him.

Return to New Tristram

Head left to locate a waypoint. Use it to travel to New Tristram.

Talk to Deckard Cain

Talk to the old man to end this quest (Cain can always be found on the main square).
