Priest Grinding guide 1- 40

Summary: Do very, very few quests from level 30 to level 52. Then do quests as quickly as you possibly can until you ding at 60.

Levels: 21, 22, 23, 24
Where: Southeast Duskwood (Tranquil Gardens Cemetary) Mobs: Level 21-23 Skeleton Warriors/Mages
Comments: The area is packed with mobs and has a fast respawn rate. Should get around 18,000 EXP/hour here. Do the quest titled 'The Night Watch' because it is a really good grinding quest.

Levels: 24, 25, 26
Where: Northwest Duskwood (Raven Hill Cemetary) Mobs: Level 23-25 Skeletal Fiends/Horrors
Comments: If this area is packed with players, you can always jump over to the Ghoul area north of the Skeleton area. Watch out for Mor'Ladim. The second 'Night Watch' quest is here. Raven Hill is rather far away from the graveyard; don't die as you will have a long walk.

Levels: 26, 27, 28, 29
Where: Duskwood Mobs: Level 27-29 Ghouls (Raven Hill Cemetary/Catacombs), Level 26-30 Ogres (Ogre Mound)
Comments: I'm sorta at a loss about what to say for these levels. The Worgen quest gives a 24.2 dps wand (if you didn't do BFD) and the Bride of the Embalmer quest gives a 7 INT/7 SPR pair of shoulders. Do whatever for these levels, but if you're going to quest it up in Duskwood, do bunches of quests at a time to minimize travel time. Set your hearth to Darkshire, also.

Levels: 29, 30, 31, 32
Where: Northeast Duskwood (Manor Mismantle) Mobs: Level 29-30 Fetid Corpses
Comments: There are two treasure chests here (one in the middle of the area, one in the house). Be careful of Stalvan inside the house; stay away from him since he curses you. You'll need to remove the disease these zombies give you. You'll get lots of wool and a bit of silk

Levels: 33, 34
Where: East Desolace (Kolkar Village) Mobs: Level 31-34 Centaurs
Comments: There is one grind quest here for Centaur Ears, and the quest reward is a 7 SPR ring. You can easily get a ton of silk and mage weave here. Level 33-36 were the slowest leveling paces and the most painful. I'm wondering if there are better places to grind than in Desolace (e.g., Arathi trolls perhaps?). If you want my personal opinion, avoid Strangle thorn Vale, especially if you are on a PvP server as you will not get anything done quickly.

Levels: 35, 36
Where: Southeast Desolace (Magram Village) Mobs: Level 32-36 Centaurs
Comments: This can be a tough area to grind in, if you let it be. You have to find the correct spot and just get in a groove. For me, I used the spot on the map where the land juts into the lake to form a peninsula. There is a small tower near, and you can cross the bridge and kill the mobs on the island if you would like. Beware and avoid the Pack Leaders at all costs (they spell easy death). Figure out their movement paths so that you can avoid them.

Levels: 37, 38, 39, 40
Where: Northwest Badlands (Dustbowl) Mobs: Level 37-39 Lesser Rock Elementals
Comments: Your greatest grinding will probably take place here. Your mount money will come from here. Elemental Earths sell for 75 silver to 1 gold a piece on the auction house on my server, and stacks of 20 Solid Stone sell for 1.5 gold to 2 gold. Make use of the auction house! At level 40, I had about 200 gold thanks to Badlands. The Elemental Earths are also good if you are a tailor (power level your tailoring skill with the Earthen Vest pattern. There is also a grind quest for the Lesser Rock Elementals. IMPORTANT NOTE: Make sure you are NOT using a nature-based wand. Elementals are IMMUNE to nature damage. If you are an enchanter, you can craft yourself a Greater Mystic Rod (level 175).
