A short guid about farming Leoric's Signet.
Why farm lvl 14 ring? Because it gives you 20-30% experience gain. Spending a couple of hours farming this ring will bo more than worth it's time if you're planning on advancing in Paragon levels:

I'm farming with a monk and I believe that's the best possible class for the job. Here's my build
Basicly you should run WITHOUT a companion or Mystic Ally - they tend to run offscreen and you either have to chase them and check the item drops, or ignore them and potentially miss the drop - lose/lose situation.
You should instead apply Mantra of Conviction - Submission. At the moment it causes 17% of your DPS to all mobs around you, which means they die instantly. The range of the mantra is within screen range, so you should be able to see all the item drops.
I'm running MF capped (300%) with 12% movement speed boots + 10% from Fleet Footed passive. Basicly, you won't have to attack a single mob (besides goblins, they have some strange resistances).
Ring can drop in Act 2 of normal difficulty. I'm starting my run at Vault of the Assassin to get fast 5 NV stacks. Then I proceed to Dalghur Oasis + Sewers of Caldeum + Ruined Cistern.
After a week of on and off farming I've finaly found my ring (perfect 30%, go me!). Here's a list of other locations ppl reported the drops:
2x Forgotten Ruins (Dalghur Oasis)
1x Tomb of Khan Dakab (Dalghur Oasis)
1x Tomb of Sardar (Dalghur Oasis)
1x Ancient Cave (Dalghur Oasis)
3x Dalghur Oasis
2x Sewers of Caldeum
1x Ruined Cistern
1x Ancient Waterway
1x Vault of the Assassin (warning, uncomfirmed)
I strongly suggest getting at least one gear piece with increased pickup range. Not only you may make a little bit of gold on the side (made about 300k g yesterday), but it clears the screen space, so you have smaller chance to miss THE drop.
I've made around 4 mil exp in 7 hours worth of farming, which is a nice bonus.
EDIT: I've finally found the ring myself and we have many reports from other forum members - so this method is 100% accurate & working (at the time being, at least :P).
