Since this was last written things have changed a bit.
Now it seems the Mages that go to doom are there to SUPPORT the warrior. It is almost imposible for a Mage to get looting right and even less to obtain an Artifact. Warriors/Archers should think of 3 weapons to take to Doom. Fire or Cold, Deamon and Undead. There is really no other need for any other weapon.
Here is what I think works best in Doom.
Have Warriors, fight Bosses upclose. Use the HONOR Wall, works great down there. Archers stand right behind a wariors that is fighting the boss. If the Boss turns on you just un arm and step away. They might chase but all you have to do is not hit them and keep going in circles around the warrior; the warior will get it off you.
Mages unfortunetly dont come close to doing enought damage. I am not saying they don't but I just dont think it's worth it. In my opinion if you were to take 2 decent wariors down there you could have alot of fun. Just keep an eye on each other. I usually go down there by myself. Havent had any real probmes yet. Now another great thing I have seen is Tamers working together. Get a few Tamers down there with a decent WW you will defenetly clean house. I have seen GOL use this tactic on the DF. They had a few healers on the WW and he rocked the DF. The other people there were taking care of the Spawn. But if you are a warior and can not find anyone else to go with you all you have to remember is to take a Bonded pet with you.
You will need it when you get to the Dark Knights. Just tell it to follow and kill one at a time. Everytime it hides dismount and it will show you were its hiding. Use Purple Pots to reveal it. If its hiding and you can not find it verry simply dismount and tell it to guard you. Walk around. When you get close to them they will make a sound. If it flags on you wile walking your pet will autimatically walk towards it.
Now for the ones that come after that, the Squid looking thigs. Be carefull with those. With 0.00 Magic Resistance it has droped me from 120 strenght down to 68. So you have to be carefull with them.
There are a few more ways to hunt down there succesfully but those examples above are the best. Hope that helps for some of you who were wondering.
