Hello, im using l2jfrozen rev 1118, and i'd like to edit the amount of buff that the skill Cancellation Removes, i've tried to change in xml files but nothing, i also have tried changing this lines on Eclipse but nothing.. 

 

         L2Effect[] effects = getEffected().getAllEffects();
         int maxdisp = (int) getSkill().getNegatePower();
         if (maxdisp == 0)
         {
            maxdisp = 3;
         }
