Scorpion Harness is still useful but you should know that the price dropped dramatically and you can get them for 20-40k now. I used to do blackmage manaburn parties in Operation Desert Storm back in the days and I made a killing off of charging 20% (divided by 3-4 blackmages) from mainly the venmous claws. Everyone and their mother used to want one, so now the market is flooded with them and theres better gear at higher level.
