NPC dupe method.

Something an old friend of mine and me stumbled upon 2-3 years ago in a few servers.

Upon buying something you'll get something like this.

[3D 00] [00 03] [00] [B4 A6 4F 00] [01 00 00 00] [00 00] (Broken down structurally. int, short, bytes)
^^^Possibly wrong, if it is....
[3D 00] [00 03] [00] [B4 A6 4F 00] [01 00] [00 00 00 00]

B4 A6 4F 00 is the ID.
It translates to 5220000 (Or something close.)

Lets take a look at the 01 00 00 00 however. It signifies I'm buying 1 Net-gachapon ticket.

What we want to do is this.

3D 00 00 03 00 B4 A6 4F 00 01 FF FF FF FF 00 00 00 00 00
and insert a negative into the amount bought.

and you should now have more of the currency you needed to buy the item. Here are some screenies.

Want more just post in the thread. I have some spare time to find these. Also server is quite easy to find out. Same one Blitz filmed the 7th Day Market dupe on.

And yes, you should DC.

If you know any other duplicating method please tell me this one is working and its really great.

Thanks

One day i saw some guy duplicating his nexon cash, and I was wondering if you know how to?

Send me the link of that thing or something ?

Google. it. Its online.

Not working for melons. Could you post a packet?

@iAngel
What are is it going to dupelicate?
Also when I send the packet I crash, Do I need to block anything to prevent it?

Thank you in advance.

AWESOME Thanks <3333333333

Hey, will npc duping causes LAG/Massive DC to the server?

Does this still work?
