Let's discuss the topic.
So, recently getting jailed for speed hacking... I was like... whoah..they ban on a private server? no wai.
Anywho...I don't use hacks for advantages in PVP, just use it to move from place to place.
So...I believe this is possible. Just a question of how.
I believe if you are able to "change" the form you are in, you'd be able to escape with a return scroll. Perhaps.. only speculating.
By change, i mean make the server believe you are different form, and not this little blue ****.
*cough* packet editing anyone?
