OK, so you’ve just killed Sneed, now for the Foundry. The spiral ramp isn’t a problem for you as a healer until you get to the bottom. Stay to the outside wall. If you get too close to the inside rail, you will pull a goblin or two or three from below the ramp or on the center platform. With all the healing going on all the way down the ramp, you are going to be high enough on the threat meter to warrant an attack, then you will die, then everyone else will die, and everyone will be pissed at you for being a noob. Don’t do that. As long as you can use good pulling techniques and clear the room, the boss, Gilnid, is easy. He drops a nice ring and crappy pants.
Clearing the mine to the next set of doors is easy as pie, and just mana/heal up before you blast the doors down with the cannon. As you go through the doors, make sure you clear out the goblins to the right if you have anyone pretty low level in the party, because they will come running after a 14 or 16. Clearing your way to Mr. Smite is smooth sailing. Have the tank go after Mr. Smite and generate a lot of aggro before anyone else hits him. Besides, everyone else needs to go after the guards. Put Renew on the tank and take care of the rest of your party. Smite will stun everyone twice as he goes for new weapons, but as long as the tank has aggro, everything will be fine.
My preference when I am group leader is to go left at the ramp and go after Cookie. He has the best wand for many, many levels to come, and the group is doing a good thing to make sure their healer gets some goodies. Otherwise, he drops his mace, which is so-so, but not great by any means.
Go back to the ramp and head around the other way. This is just killing mobs that are obviously more resilient than the ones at the entrance, but nothing special. When going up the final ramp, make sure any lowbies stay close to the edge away from the ship if the patrol is walking by. You don’t want to fight them and trash mobs when partially prepared. If you successfully clear the ramps and get onto the ship, mana up and heal for pulling the patrol, which includes Captain Greenskin. He drops a great staff, but the quest reward for Van Cleef is a better staff for priests. Regardless, either staff will be replaced by the Illusionary Rod in SM in your 30s. The patrol is pretty basic. Just heal. If you have a good tank, you’ll be fine.
Now for the moment everyone in the group has been waiting for: Van Cleef. You all want his head. Why else would you be in Deadmines? If you have a high enough rogue or stealthable player, have them stun VC and start in on his guards with the other 3 members. When the stun breaks, the tank needs to take him fast. When he gets to 50%, he will spawn new guards; ignore them. Take VC down fast so you can concentrate your healing on the tank for that part, and then spread it out for taking out the new guards. Loot the body, turn in the head, and you are done. Congratulations.
