The Pits can technically drop any item other than torches-annis-uber keys and organs-standard of heroes-tamoe highlands. Some of the better drops are Windforce, High Runes and uniques like Griffons. However, they are mostly run for socketables like 15//15 armours, eth armours for bugging and open socket Berserker Axes etc... Full of pack uniques monsters. Any character will succeed basically.
The Countess is located in the 5th level of the Forgotten Tower and is surrounded by dark archers and Ghotsts. She herself is very rarely light immune so Light Sorcs are good/ The Countess can drop Terror Keys (up to three at once) and is TT66 in Hell, she also has her own unique rune drop which can go as high as Ist, and as high as Lo on her normal drop list. She is easy to run and is good for making cash at the start of ladders.
Andariel is loacted in the 4th level of the Catacombs and has a Tc level of TT69. She is well known for her jewelery drops and I get my fair share of charms from her and gems from her minions, Shakos and War Travellers are also not a rare sight. Andariel has a reduction in fire resist so fire sorcs are a good option here, orb sorcs also work well and they rip through most of the minions, my personal favourite however is the light sorc once more.
The Summoner -
The Summoner is located down one of the 4 ledges leading off from the Arcane Sanctuary WP, the ledge is chosen at random. Although the summoner rarely drops any actual good items he drops Hate keys (up to 3) and i've had a bunch of rare rings//amulets and an eth armour. The summoner is sometimes cold immune so a Light sorc is a great option here.
Travincal is well known for it's HRs, gems, gold and rare items. I've also in my time and found a fair few unique amulets//rings 2 of which were soj and 1 was maras. They are however annoying to kill and i would advise running them only if you have a Hammerdin or a good sorc like light with infinity or for immunes.
Mephisto is a great runner, drops are frequent and she is known for drops such as Zakarum, Shako, War Travellers, Gores, Wizzy and Arachs. Dont miss the council here, there easier then Travincal and they once dropped me homu + occy in one run. Mephisto is located in level 3 of the Durance just beside a river of burning lava and a red portal. Orb sorcs are good here. Watch out for the ball thing wink.gif
Chaos Sanctuary -
Diablo himself is not the main part here, it's his minions... they have the ability to drop good items such as Dracs and other uniques. I've heard of many Vex's etc being dropped although I myself have only found Mal, on Open tongue.gif Diablo himself can drop good items ofc and his GCs can be sold or cubed for 45 lifer skillers. Hammedins and trapsins are best here. Chaos is found along the Flaming River
Pindle is like an Alvl85 area except Tyreals//Arach and i think one more item (confirmation of this item would be great). Pindleskin can be found through the red portal opened up by Anya, i would do Nili and just tele back to do Pindle. Some good drops from Pindle are Griffons, Crown of Ages and Deaths Fathom. Fire sorcs are good here if you have a good merc.
Frigid has Eldritch and Shenk, both of which are good for random uniques like Dracs, Silks and low set items. There main asset however is the amount of rares they drop. Most characters can run Frigid but Eldritch and his minions are cold immune.
Nilithak is down one of the 4 sprouts of the Halls of Vaught, accessed through the Halls of Pain, tele back from here to the Halls of Anguish to do Pindleskin. Nili can drop Destruction keys but be careful as his corpse explosion is violent. Just aim for him and kill him before he kills you, with natures peace you should be ok. His GCs are also good for cubing to get 45 lifers. Hammys are good for the easy tele on and kill, my Tal Light Sorc can run him though.
Baal is amazing, any item can drop from Baal except the same as the Pits. Getting to him is easy, simply tele to the Throne of Destruction and kill his minions, he'll disspear. Follow him. The experience is good, just make sure you can kill them.
