The Crypt of Nadox is right off the Gulf of Gunthak, which has a book from PoK to it. Nadox is another one of those zones where you should be expecting to get raw cash over items to sell in The Bazaar. You'll easily be able to blow through this zone in the upper 70's raking in a decent amount of cash.
After some time in Nadox inventory space may start to become a problem, but you'll usually get bored before that will happen. I would recommend destroying the swords, maces, daggers and whatever else the living trolls drop to free up space.
Veksar is located in the Lake of III Omen in Kunark. It contains a slew of different undead creatures. They all hit fairly weak, but do have a half way decent amount of HP. You'll find that they usually drop 6 or more plat per kill and Steel weapons that will sell for 6pp at a vendor. Your inventory will get loaded up fast here and so will your wallet!!!1111 lawlz funnai joke.
Veksar is huge, you will probably get lost many times in here. Luckily there is no shortage of mobs for you to kill.
You'll find the following nammeds wondering around;
A lot of the junk off the nammeds is vendor trash. You can try to sell it in the bazaar if you want but I think you will just be wasting your time
PP Per Hour Estimate: 3,400 to 5,000
Items You Will Find In Veksar:
Defiant Gear
Shabby Fine Spell Scroll
Steel Ch'Ror
- Sells to vendors for a good amount of plat but takes up a whole inventory space. I recommend destroying them if you get too many and need room for something more important like defiant gear.
Steel Mak'Stor
- Sells to vendors for a good amount of plat but takes up a whole inventory space. I recommend destroying them if you get too many and need room for something more important like defiant gear.
Steel Re'Stek
- Sells to vendors for a good amount of plat but takes up a whole inventory space. I recommend destroying them if you get too many and need room for something more important like defiant gear.
Steel Ta'Nak
- Sells to vendors for a good amount of plat but takes up a whole inventory space. I recommend destroying them if you get too many and need room for something more important like defiant gear.
Sunshard Pebble
Sunshard Ore
Razor-edged Shan'Tok
- Sells to vendors for a good amount of plat but takes up a whole inventory space. I recommend destroying them if you get too many and need room for something more important like defiant gear.
Blackfeather Roost is a great farming spot for levels 72-75. Killing the animals on the first platform will give you a good combination of Vendor Trash and Cat/Bear Pelts. If you're low on AA's I'd like to advise you that a healthy mountain puma and a cunning mountain puma can put out a decent beat down for being green to you.
There are a few pieces of gear here and an Aug. I put them in the Items of Interest section incase you can use them.
PP Per Hour Estimate: 3,500 to 4,500 (Not including items to sell in Bazaar)
Something to keep in mind is, if you plan on farming here awhile I recommend vendoring the stuff that the nammed mobs drop. It's worth usually 300pp + at a vendor.
Plane of Hate has to be close to my #1 all time favorite farming locations. Not only is the loot here great but there are literally thousands of mobs for you to kill. How many mobs you can pull at a time in PoHate will depend on what level you are and how many AAs you have. With right around 1,000 AAs I can pull close to fifty and kill them all without too much of a problem. Each of the mobs has a chance to drop a valueable gem like a Diamond, Peridot, Ruby, Black Sapphire, etc, etc, on top of the usual 5 to 7pp a kill they give. There is one thing that sucks about PoHate, however and this is having to wait 5 minutes from when you leave combat to med.
PP Per Hour Estimate: 2,400 to 7,800
Additional Note: The class specific armor that drops in Plane of Hate can be turned into NPC's in PoK for gems, like Diamonds, Peridots and Blue Diamonds. If you'd like to do this quest you can view the page on allakhazam here. It is entierly up to you if you want to hold onto the armor, or destroy it so you can farm longer. Usually it will take a good hour or two to fill up your inventory.
The Hole is another one of my favorite farming spots. This zone is jam packed with undead for you to kill and harvest the plat from their corpses! I won't give you a specific direction to go here, since everywhere is really good. Just sit back, get lost, put on good music and kill away. Also I'd like to recommend if you don't have gate you bring gate potions, It makes it a lot easier to get out.
