Ladies and gentlemen, it seems a new exploit has just entered the building.

I don't get why this is so hard, Nexon:

• Set the variable boomrate to the amount of earlier enhancements
  
• If scrolltype is not advanced, increment boomrate by 2
  
• If boomrate is over 9, set it to 9
  
• set boomrate := boomrate * 10
  

Now, boomrate is the probability in percent for exploding your item. If the item doesn't explode, the scroll works. This can actually be done server-sided, Nexon. Duh.
