What does Wirt's Bell do?

Question

I came across a vendor, Squirt The Peddler, in act II that sells: Wirt's Bell for 100,000 Gold. What does that bell do and is it worth it?

Answer 1

It is used for reaching the secret level (along with a bunch of other items and crafting which actually costs more money). Whether spending that much to reach it is "worth it" is entirely up to you :)

Answer 2

You need:

• that item,
• 50,000 G,
• the Black Mushrooms, found in Cathedral
• Liquid Rainbow, found in the Mysterious Cave, located in Dahlgur Oasis
• Gibbering Gem Stone, found in Caves of Frost lvl 2 - dropped by Chitara random purple mob
• Blacksmith plans for staff of hurting (dropped from Izual)
• Leoric's Shin Bone (found in Leoric Manner by the fireplace randomly)

When you have all that, go to the blacksmith and ask him to build it (50,000 G); after you assemble it go to the cow bones (Act I) and enter the level called Whimseyshire. It was awesome and totally worth it.

Be warned! You should be at least level 30 before trying to enter this realm. (Normal mode; I dunno about the upper levels.)
