The armamentalist quest can be done rather easily if you know what to do.
First, you need to go to Quarantomb. The first room is just a small room with one entrance, and then next room is a big maze. When you get to the maze room, walk up a bit near the slab (but not right next to it). Enemies here spawn rather quickly. When one of the enemies comes towards you, run back out to the previous room, and then back to the maze room in the same spot and watch the enemies spawn. Keep doing this until you find a metal slime. They aren't super common, but I've seen a metal slime spawn, fought it, then another one spawn immediately afterwards.
When you actually find the metal slime, you should have someone with metal slash (a sword skill). Metal slash normally does 2 HP damage, which doesn't sound like a lot, but all metal slimes have only 4 HP. Have your sword guy use metal slash for 2 HP, have another party member attack for maybe 1 HP, another defend, and have your mage use wizard ward. If everything turned out ok, the slime should be down to 1 HP, and defend with everyone and have your mage attack for the killing blow. Granted, most of the time you probably won't be able to do this in just two turns, but it shouldn't take more than four turns. The metal slimes are also rather aggressive and don't run away too often.
