After killing the lower sorcerers, the one higher one, and the 2 death knights, you will get the fang, boomerang shuriken, sorcerers heart, 2 giant swords (nice 2-handers, mook only), some gadgeteer items, and umm something else, don't remember what tho

There's a couple of undead after the harder fight tho before you get your hands on the fang and the shuriken, and some of the other items.
