I tried to search but i didint find this bug so i wil rite it down :)
This bug works in 1/3 maybe servers. (Where you can drop adena on the ground)
1.Open L2phx .
2.Open L2 .
3.You dont use main chars, cause if there is low online, admin will see what you are doing.
4.Create new char, and go hide somewhere :)
5.Take all aden from other char, if you dont have then you go borow from a friend.
6.When you drop aden, look at l2phx packets, find ,,drop item", and copy it to send packs.
7.Pick up your adena that you drop, and again look at l2phx packs, find ,,pickup item'' or somehing, copy it to send packs.
8.Put script on 1-100 m/s
9.Now your char is picking up and droping the adenas, now depending from server = When chat wil rite "This item cannot be discarded"
Turn off the script, and make "restart".
voila, now you have double adena that you had.
Extra info...
Many servers only 1 drop and 1 pickup pack is not inuf.
So you can Improvize, like... Drop,Pickup,Pickup :)
I leave it to your imagination. Good Luck.
