a scorpion  

The scorpion, decaying skelleton, mosquitoes, a pygmy barricuda, a swamp leach, a giant swamp leach, a barricuda, and an iksar outcast are all found in a secret tunnel in Cabalis East. I strongly reccomend hunting there in the low levels, especially if you are a monk. You can bank and sell right outside this tunnel. The way you get in it is you jump into the water. Then you swim to the east end of the lake. You should find a tunnel there with barricudas and pygmy barricudas. In this tunnel you will find I believe 5 different places you can jump up and fight. Jump out of the water in the fourth one. Then follow a one way path till you reach the fifth one (you cannot jump into the fifth one for some reason). Here you should find the room. There is another secret room if you walk into one of the walls. When you want to sell/bank, just jump into the water and swim out.

Actually they con blue to my forth lev monk, forgot I had gone up a level.
