increase rogue archery speed : KO Submissions

Ok,this is more like a bug than a hack because it totally relies on the server.
first of all,ONLY use it if your an archery rogue (bow),means if ur not using sword/dagger/club.. it will be verry bad for you if your a close combat person.
ok here how it goes : once you teleport to luferson castle/EL morad from moradon make sure once your screen show teleport to then earest town using the teleport gate,im not so sure if it will work in EL morad,but in karus try teleporting to raon camp,this of course exactly at the moment your charactor shows.
you will notice that your image will be 50% invisible (just like when you respawn) for a long time,and also notice that when you shoot arrows your casting speed will be GREATLY increased.
however you will not be able to attack using a dagger or a close combat weapon unless you use skills instead.
i've been using this bug for 2 months now,means im not sure if it's possible with mages and etc..

let me know if you find any difficulties in understanding.

PS: once you teleport to raon camp,re-teleport to linart village as fast as you can before your invulnerability is removed,or else you will fail.
