After watching a couple videos on the subject, and spending the last few days seeing what I could get, I decided to write up a little guide for it. Leoric's Signet is a level 14 ring that offers 20-30% bonus experience, and was made popular by the introduction of Paragon Levels. It's not as comparable to the new Hellfire crafted ring, but both together can offer a ton of experience bonus, and the Leoric's Signet still sells very well.
First things first. Magic find, magic find, and more magic find. You don't have to worry about your dps, since you'll be farming such a low-level area. Even at Monster Power 10, nothing here will even touch you at level 60. You should have no problem coming close to the cap for gear.
Next, Movement Speed. Since everything's going to die so fast, you're going to want to mow down everything as fast as you can. Boots are obvious, find a pair with 10%. Other pieces have movement speed as well. For the sake of keeping it cheap, I recommend Hammer Jammers and Lacuni Prowlers. You can get the Legacy version of the Prowlers for cheap, or get the level 60 version for 100k or less. Another good choice for bracers is Slave Bonds. The Compass Rose comes equipped with Magic Find and Movement Speed without resorting to random chance. The Flavor of Time is an amulet with Movement Speed, but here you'll be giving up a chunk of Magic Find, and, as you see, there are plenty of other options to move faster. However, keep in mind that the max amount of Movement Speed you can obtain through gear is 25%, any excess will be wasted space.
With a monk, you're not going to be using your Primary attack at all. Everything comes down to watching your targets die as they near you, and getting as much movement speed and Spirit regeneration as possible.
Fleet-Footed: 10% Movement Speed that goes over the 25% cap
Tempest Rush: More Movement Speed that breaks the cap, also helps kill things. Use it for travel purposes. Northern Breeze reduces the channel cost, and Tailwind increases the movement speed. Both seem to be good choices.
Mantra of Conviction: Used with Submission, this will be your main ability. Submission deals ~20% weapon damage every second to anything affected by Conviction. You will literally watch everything die.
Chant of Resonance: Increases your Mantra duration by a large margin, allowing you to spend more time using Tempest Rush. Also gives you 2 Spirit per second.
Exalted Soul: More Spirit regen, and increases your Spirit pool by 100
Wizard: Requires stand-still nukes unfortunately. Disintegrate seems to be the most optimal way of handling mobs
Teleport/Wormhole: Allows for quick movement
Storm Armor/Scramble: Double effectiveness, hits nearby enemies, plus offers a movement speed bonus
Diamond Skin/Prism: Reduces Arcane Power costs while under Diamond Skin's effect
Critical Mass: Helps to get that Teleport cooldown back
Evocation: Also reduces cooldowns, getting more teleports
Demon Hunter: Will work a bit like the Monk in that your damage aura will be your go-to damage
Vault/Trail of Cinders: For mobility plus extra damage on top
Chakram/Shuriken Cloud: Has a similar effect as a monk's Submission
Tactical Advantage: More mobility while using Vault
3. Farm Run
Change your quest to Normal difficulty, Act 2. Pick the quest, Lord of Lies, with Monster Power 10. First things first, you want to build up your Nephalem Valor stacks before you hit the farm spots. Head into the Caldeum Bazaar and go into the Flooded Causeway. The Ruined Cistern is good for 1-2 elite packs. This is a small area and should only take a minute or two to complete. Afterwards, port back to town, and take the waypoint to Black Canyon Mines. This is another small area, circular in nature, that will give you 2-3 more elite packs. Your next destination depends on how many stacks you have now. If you have four, port back to town and take the waypoint to Road to Alcarnus. Head east into Alcarnus, which is another small area with a guaranteed elite group, sometimes two. If not, head northwest from Black Canyon Mines into Stinging Winds. You can find an elite group wandering around, or multiple dungeons that can offer at least one elite group so you can head to Alcarnus. Also, since 1.0.5, Respledent Chests now give a stack of Nephalem Valor. So do Events, but you shouldn't run into any on this run.
With five stacks, you're now ready to farm. Port back to town, and take the Sewers waypoint. The Sewers is another small area, a little bigger than Ruined Cistern. Remember, you want to kill as much as you can, not just elites. With up to 500 Magic Find, anything and everything can drop legendaries. After the Sewers are clear, port back to town and take the Path to the Oasis Waypoint. This is your bulk area of farming. There are plenty of things here that can spawn. You have the two spots that spawn the Mysterious Cave (where you find Liquid Rainbow for the Staff of Herding pattern). Ancient Cave and Flooded Cave are also good caves to farm, as are Tomb of Sardar and Tomb of Khan Dakab. You can also do the Forgotten Ruins, the quest area here. There are a few rare spawns in the area as well, including one that spawns frequently,Sokhar the Keywarden, and drops gear as an elite group would, as opposed to a usual rare (meaning it guarantees a rare). All in all, the entire run should take about 30 minutes. Once you're done, head back to town and sell what you don't intend to auction (see below).
Alternate path: Use Black Canyon Mines and Howling Plateau to get your NV stacks up. The Ruined Cistern can drop the ring. Also, after Oasis, feel free to continue through the waterways and Desolate Sands, as those areas have a smaller chance, but still a chance, of dropping equivalent level items.
4. Auction House
So, you're farming this low-level area, and you're not making any money. What do you do? I suggest picking up (most) rares along the way. Some people may not need the money, and just want to blow through everything to finish the runs as fast as possible. That's fine. But don't sell these items short. With a little practice, these items can garner you plenty of gold. Of course, all the legendaries are pretty nice. Scrimshaw seems especially expensive. But what about the rares? I'm not very keen on selling items, but I'll tell you what I can.
First, shields and two-handed weapons seem almost worthless. Even with prime stats, I haven't found one yet that is worth putting up. I figure everyone dual wields, and wizards and Witch Doctors use their respective off-hands. Next, items seem better off with a primary stat on it, and high numbers at that. Granted, the percentage bonus just doesn't seem as good, when another 1% of 20 damage is, well, one damage. Weapons, helms, pants, and chest pieces need to have a socket. With the ability to put a gem into an item that doubles its stats (or more), socketed items are extremely valuable. As far as secondary stats, you can't go wrong with Magic Find and Bonus Experience. Finally, rings and amulets. I LOVE getting rings and amulets, no matter what level. They always seem to sell better than anything with less stats. Even without a socket, most can sell really well.
If you give it a go, good luck. Anyone who can provide me with good info on non-Monk (or better Monk) specs, feel free to say so here.
