[Share] Java CP Exploit Fix

[Devon]

I found this bug working in an old L2J C5 server. Then I tried it in the Interlude servers in HopZone and it worked in most of them. In the latest revision of the L2JServer pack it doesnt work but it works in L2JFree.

 

I searched for this bug here and I didnt find it so I guess it isnt posted so I share it here...

 

- Equip a weapon that increases CP. (Example: Infinity Wing)
- Heal your CP.
- Unequip the weapon.
- If your current CP is more than your Max. CP the bug worked.

If it worked add this code and compile your pack:

Just an FYI, this is more fun to do with a cursed sword. Get a cursed sword, go into the water and drown and die. Voila, you have 100k+ CP and no sword. ;)

Karma is just a reward and even if the share is a copy paste, he deserves to be rewarded.

 

And please speak better, i know that giving karma is terrifying you, but don't overdo it ;)
