Last night, NCsoft took down Blade & Soul Korea for an emergency maintenance, which lasted 1 hour. Curious players wondered what happened, and it was later discovered that a fix has been applied to solve a critical exploit in the game.
According to information, the source of the exploit is the cash shop chest (0.45 USD each) which gives out random items, including a material used to craft legendary weapons. 1 player apparently found an exploit which gives him a 100% chance of obtaining that material (if reaction is fast enough).
This caused the price of the material, usually trading for 70,000 gold, to drop to 7,000 within 12 days. The player mentioned reportedly sold the material for real cash at 1 of the virtual items trading websites, earning over 2,000,000 points.
1 point is given for every 10 Korean Won traded, which meant he garnered a revenue of over 200,000,000 Korean Won (around
1,800 180,000 USD). NCsoft is now tracking other players who abused this exploit.
