L2J Server

Is exist attribute what makes NPC to ignore skills like silent move, dance of shadow etc? When I first have on my server a problem with spawnkilling then I spawned on spawns some anti-pk guards but they ignore PK with silent move . If someone have an solution please write it here

Siege guards ignore silent move/dance of shadow, you can use their code with anti-pk guards

really thanks but I need to use this "skill" of siege guards on some mobs also
