Saw the post on PoN and thought this zone should also be described as well. For someone reason mobs here have ridiculous amounts of HP. The trents can double for up 300 and when they stun its quiet painful as you will see all your HP disapear within seconds. But with this aside the experience is simply amazing. Stay in PoN till 53. Anything before 53, the resists are too great and you will spend too much time chant kitting vs. actually making exp. Yard trash (arachnids, hatchlings, ravens, trents, bats) DO NOT SUMMON. A lot will still con even or yellow at 53 but dont be afraid to make that pull. North of the graveyard is an old withered tree. Make a path from graveyard to this tree, avoid large circles, adds can be an annoyane but manageable. Run through your chant kite, i recommend oos instead of chant of flame if you have it. Soloing you will see 1-2% a kill at 54 and 55. Approx 5 min per mob, usually less. Do not bother with your charm as only young bats can be charmed and i hardly see them around.
However....
To speed this process up i highly recommend finding yourself a partner. Know a good necro/sk/druid? well invite them to join the fun. Run your chant kite till mob is at 90%, let the druid snare, chant to 80-85% and let the druid start dotting. Mobs will fall in about 3 min and the exp becomes slightly better then soloing. Same with necro, sk...snare at 90, at 80 let the sk or necro pet follow behind the mob and beat the nightmare out of it (refered to as aggro or reverse kitting). General rule of thumb is "they get aggro, they will die". Keep your chants on, selos recast will be needed around 70% and 30%.
Have fun and much luck to you all. Hope this will help someone out.
