Obtaining the Sulfuras, Hand of Ragnaros

Intro:
This mace is one of the best two-handers in the
game. There is a fragile limit to who should/can use it though, most
would say this goes to a DPS warrior, although Paladins and even
enhancement Shamans have been seen with it. While Thunderfury require
you to farm BWL for elementium ore, everything you need for Sulfuras
can be found in Molten Core or in the outside world.

How To:
To make Sulfuras, you'll first need to make a Sulfuron
Hammer. A blacksmith with 300 in skill is needed for that and the
plans for it are sold by Lokhtos Darkbargainer at the BRD
tavern (the same guy you do turn ins to for increased Thorium
Brotherhood rep after you reach honored). You need to give him a
Sulfuron Ingot (dropped only by Golemagg in MC) to receive the plans,
however there is no rep required.

Once you've got the plans it's time to start working on those
materials for the hammer. You should already be way on your way as
you've spent some time getting to Golemagg in MC.

What you need and where to find/how to make it

1. 8x Sulfuron Ingots (From Golemagg, as mentioned. This
   is in addition to the one you used to buy the plans)
   
2. 20x Dark Iron bars (Which again means 160 dark iron
   ores. Dark iron is mined a few places in Burning Stepps and Searing
   Gorge, but are most easily found inside Blackrock Dephts and Molten
   Core itself. To melt ores into bars you need to learn it from one of
   the dwarves from the Chamber of Seven, and melt it at the Black
   Forge, next to the MC portal in BRD).
   
3. 50 Arcanite Bars (Arcanite bars again. 1 arcane
   crystal and 1 thorium bar is required per Arcanite bar and it takes
   an alchemist 2 days to make one. Better get your guilds alchemists
   ready to contribute)
   
4. 25x Essence of Fire (these drops from fire elemtanls
   in Burning Stepps, Searing Gorge and the Blackrock instances. They
   can also be created by alchemists (275+ and a Philosopher's Stone)
   by transmuting air to fire, but the process has a 24h cooldown).
   
5. 10x Blood of the Mountain (This are rare drops from
   Thorium veins)
   
6. 10x Lava Core (Drops off of most mobs in MC)
   
7. 10x Fiery Core (Same as Lava Cores, drops from MC
   mobs)
   

The blacksmith should have all he needs to make Sulfuron Hammer.
In itself it is an excellent DPS weapon (63 DPS), but the real value
is it's ability to turn into Sulfuras, Hand of Ragnaros. For this you
need ONE thing - the Eye of Sulfuras. Unfortunately it only drops
from Ragnaros at about 2% drop rate, which means you could easily
farm Raggy for a year before your guild gets it.

Note that the Sulfuron Hammer is BoE, so the one who makes it need
not be the one chosen to receive Sulfuras. The Eye of Sulfuron
however is BoP, so make sure the chosen one loots it. Sulfuras is BoP
as well, no-one can loot the eye, make Sulfuras and give it away.

Once you got Sulfuron and the Eye, you are 45 seconds away from
being the proud owner of this beauty.

If that doesn't work and you need gold quick, I recommend The MMORPG Exchange WoW Gold. They deliver quickly and are cheap! I usually receive my gold within 20 minutes. They're my secret weapon, I highly recommend them!
