i think what he meant was....
change your height to max then move around, let's say left and right, then when you reach your highest height,let's say 17700 example. use siegekit mode "works with Accretian Launcher" then when your in Siege mode, change you height to normal....
you can now hit monsters or PK without being seen by anyone
but you can't move, if you move, you'll be seen by others
LOL
useful in hunting PB's
i don't use this in PK's
i use this when killing PB's
