I am not sure where to start other than suggesting you peruse The screenshot: This is just 2 floors worth, NTTG, After selling multiple of each to the vendor before I realized there was nothing left in the vendors that I wanted. If I wanted to fully comb over levels 11 and 12 there would have been many more. 1-2 of each are artifact/quest type rewards, but the rest is just plain old one scattered through the dungeon. Since I was staff speciality I didn't mind, but it made me wonder if more staves were dropping because I had staff speciality. I rarely saw a sword, mace, or axe... nothing compared to this.
