WARNING: GMs know about this exploit and dont allow it, i was warned in J/ob and i have heard you can get warned in North American. Use at your own risk.
I used this little exploit in T/ob and J/ob,
There is a spot in the dark elf swamp in which there is a stone area sort of like a temple or something(sry, dont know exact loc.)In this spot you can pull monsters into a corner at the bottom and you stay on the temple area and shoot them down with a ranged attack without getting hit. I did some searching and found this screen from some other boards.
