Ok, here is what you do
Download L2 Walker 10.2.3
HERE
You will need WinRAR to extract it
Extract the file and run the L2 Walker.exe
Do not run the token, run Walker alone.
Select IA from the server list, do the username and pass and log in.
And to stack buffs(at your own risk)
Step 1:Set the walker up what u see on the top now
Step2:Go under option>and set relogin on and on 5 sec or lower make no sense
Step3:Login with the walker if it says EnterChar[x] press logout
Step4:Now the walker try to relogin again u will see packet error in the lower box u can ignore it
Step5:This time let the walker log in u will see enterchar[x] and this teal welcome massage if u did step3 correct
the walker will automaticly log off and will try again to login...so now u got your first stack dont forgett
your buffs get allways doubled 1>2>4>8>16>20 more doesnt work
Step6:Now u have to do Step3 then Step 4 and Step 5 again and that so long since u have your buffs
full stackd...its easy if u understand it so happy stacking...
