One of my favorite Alts that I have made is my Thief Acrobat, I'm considering playing it a lot more but may start over since I'm currently only at level 10, my original plan was to stay pure Rogue, I went Strength based and so far it has worked really well, but I see a lot of people with staff builds take 6 levels of monk, I am guessing for Ninja Spy.
I have no experience as a monk can someone tell me what the main advantages to taking 6 levels of monk rather than staying pure rogue?
