I want to know from you who are more experienced what the ranger is using.
It is faster, can not be stunned, and most of the blows they give insufficient region.
And for the hack, this is something new and no one wants to share something so beautiful. There is a chance this is the multi-hack posted on the hacking section here, that allows you to reset your speed and resets stuns (any stuns).
But if you want to get it, i say get someone to suck up to this person and get it. Its what i always do when i see someone using a good hack.
Thats all my little brain can tell you.
