Diablo 3 Walkthrough Part 15: Reign of the Black King

After completing the quest "A Shattered Crown", a yellow exclamation mark appears above Deckard Cain, who is standing near the Inn. Go and speak with Deckard. You tell him that you have the crown in your possession, and ask that he direct you to the lost king. Deckard tells you that with Leoric's Crown, you can at last unlocked the sealed door in the room where you rescued Deckard Cain, and enter the Royal Crypts. When you find the Skeleton King, place the crown atop his head, and destroy him.

You receive your next quest:

Reign of the Black King
Use the New Tristram Waypoint to return to the Cathedral Garden

It is recommended you sell items in your inventory before heading out, to make room for additional loot you will find during this quest. Tashun the Miner is the nearest merchant, so go and sell your unneeded items to him. Then, when you are ready to go, use the New Tristram Waypoint and choose the Cathedral Garden as your destination.

Your objective now is to enter Leoric's Passsage. Once inside, you need to go to the Cathedral Level 2 through the Ornate Door. Climb down the stairs and open the Ornate Door. Go in, to find yourself in the Cathedral Level 2. You seek to send Leoric's Spirit back to Mowiru Eikura where his tortured soul belongs. The big Ornate Door closes behind you. Your objective now is to Descend through the cathedral. The second level of the Cathedral includes many enemies such as Undead, Unburied, Carrion Bats, Skeletons, Tomb Guardians, and more.



If you run across a Scribe Lectern's, interact with it, to receive a green item such as Lachdanan's Scroll Part 1. Green items are lore/quest items, which are not equippable, but reveal more of the story. As you climb up and down some stairs, and go around a blue chasm, observe the minimap and look for either a gold arrow or a blinking circle, that directs you toward the exit. Some of the walls panel you cross will explode, and monsters will jump out of them, so be prepared for combat constantly. Also search Barrels, wooden chests, and Armor Racks for treasure.

The exit you are looking for is the Cathedral Level 3 exit. If you see it on the mini-map, and your health is low and there are too many monsters around you, you could try and make a run for it.
