What are the components, where can I get them, and how much gold do I need to craft The Hellfire Ring?

Solution 1:

The entire process is detailed pretty well on the official blog. The basic steps are

1. In each Act, get 5 stacks of Nephalem Valor and then fight the Keywarden for a chance to collect the keys/plan. (You only need to get the plan once)
2. Give the Blacksmith 12,000 gold to construct the Portal Device.
3. Use the Portal Device in Heretic's Abode to reach one of the Uber bosses and get a chance to collect an organ.
4. Purchase a recipe for the ring from Squirt for 2 million gold (only need to do this once)
5. Give all 3 organs to Shen along with 15,000 gold to construct a ring.

So its a minimum of 51,000 gold per ring (3 x 12000 + 15000), plus a one time cost of 2 million for the ring recipe.
