So I am a bit confused on the newer (since I been gone) acuity/nerve staff. On the wiki they seem to be two different topics but a lot of people call or use both the terms together which is further confusing me. Whats the difference between them? Is acuity just a variation of these nerve staffs listed here https://gswiki.play.net/Nerve_staff/saved_posts? Or are they two entirely different things and people just like to confuse me far more than my simple mind can handle? Before I go out and buy a new staff I wanted to really understand what I am looking at.

Thanks,
Rhan
