drop down from zone in. come down the passage way until you get to the second large area... this area has 7 possible ways to go... he spawns in the 6 o clock position on your EQatlas map....
roughly pos 50 pos 500
hope this helps.
fyi he is in the same general area as Magic Adept Xabok but spawns in the cul de sac just south and east of the Magic Adept
