Whimseyshire - Diablo 3 Secret Unicorn level

For those who recall Cow runs in Diablo II, it seems that the developers have not forgotten us, they have included a new version of this ridiculous level only in Diablo 3 it's called Whimseyshire, and it's not about cows. Instead its full of color, rainbows, unicorns and little angry flowers.

There is a very specific process you need to accomplish in order to open the realm though, here's a guide on how to get there: Also bear in mind that you may need to remake the game several times to acquire each of these weird items, as some of them are random spawn.

Act 1 - Leoric's Shinbone and Black Mushroom
You're going to want to take the waypoint to Leoric's Manor, backtrack towards the entrace of the building and go into the room to the North East which is beside the stairs. Check the fireplace for Burnt Logs and Leoric's Shinbone should drop for you.

The Black Mushroom can be found in the Cathedral Level 1 so to get there take the Cathedral Gardens waypoint, then go into Leoric's Manor and head South West towards the Cathedral Level 1. The Black Mushroom spawns inside one of the rooms in Cathedral Level 1 it may be a specific room, or completely random.

Act 2 - Wirt's Bell and Liquid Rainbow
The Wirt's Bell is acquired simply by purchasing it from the little girl Merchant (Squirt the Peddler) in Act 2 for 100,000 gold.

The Liquid Rainbow is acquired by taking the waypoint to Path of the Oasis. Once you're there, follow the path that is connected to the waypoint and stay along the south wall until you come across another path that leads south. Go all the way down the path and if you're fortunate enough you'll find Zavan, if not remake the game. Zavan will open the door above him for you and you can go inside the Mysterious Cave Level 1. Once inside you'll want to look for a Mysterious Chest which should contain the Liquid Rainbow. Again, it's important to note that the chest spawns in level 1 of the Mysterious Cave and does not have a 100% spawn rate, also the liquid rainbow doesn't even have a 100% drop rate from the chest.

Act 3 - Gibbering Gemstone
You'll need to Kill Chilltara (who doesn't spawn every time) in level 2 of Caverns of Frost - NOT the Icefall Caves.

Act 4 - The Plan: Staff of Herding
In order to acquire the Plan: Staff of Herding, you're going to need to go to Act 4 and kill Izual. If he does not drop the pattern, keep remaking the game until he does.

Crafting the Staff
Bring all of these items, along with your gold to the blacksmith to craft the staff. Now, if you're in Normal it will cost you 50,000 Gold. The Nightmarish Staff of Herding will cost you 200,000 Gold while the Hellish Staff will cost 500,000 Gold.
