Fishing!
Go to Valley of the Four Winds, to this location, just west of the Pools of Purity.
You should see this NPC Ghostly Pandaren Fisherman. If he is there, then talk to him and he will give you the Ancient Pandaren Fishing Charm.
This simple item will allow you to catch up to 20% more fish from pools as new reports show.
Mining!
You will also receive the achievement: Lost and Found if you happen to find just 1 of the 2 items listed above.Go to the Jade Forest, to this location: Greenstone Quarry, just at the bottom of the Tian Monastery.
Go to the bottom of the cave, and you will find a sparkling pickaxe - it is very hard to miss, if it has spawned that is.
Interact with the axe, and you will receive Ancient Pandaren Mining Pick.
This will allow you miners to loot gems from mining nodes - something that you can't do without the axe. Best part is, you don't even need to have it equipped to benefit from the spell!
Mining and Herbalism!
Get yourself an Engineer level 525, with:
8 x Ghost Iron Bolts
2 x Spirit of Harmony
and craft yourself a pair of Mist-Piercing Goggles - Again, you don't need to wear them in order to benefit from their special power. It'll allow you to see more nodes than your competitors.
I hope these tips come in handy to you!
