Explanation of the "double buff" bug (tested only on private servers with C1):
1. Buff your main character with 2-3 buffs (empower + acumen or focus + deathwhisper).
2. Run 2 windows with l2walker.
3. Type your login and password of your buffed main character in both windows.
4. Press "Login" button in 1-st window AND when it will tell you "Entered Char [X]" (X - number of character) PRESS "Login" in 2-nd window AND when 2-nd window will tell you "Entered Char [X]" press "Login" in 1-st window again.
5. Repeat it about 2-10 minutes.
P.S.: You can check your progress in Character Ifno section in l2walker (means your stats will growup).
P.P.S.: You can cummulate only 20 buffs.
