Please Help!!

[Ameila]

I too am currently a level 29 and wanting to level up.
The 'Invisble' glitches sometimes happen when tp, like Zep said. And, from what I have seen, appears as if you are only invisible to other players. Most glitches that help you level up are basically wall hacks, which isn't very affective agains't those with throwing weapons such as daggers. Also, another tip, try to even out your weapon levels. Believe me, I have completely messed up Amiela so far, and im trying to set them straght before I get too high.
Good luck!
