This may be off topic but I think this will help. For players who already know this, good for you then. (easy six paths, but doesn't solve the topic issue, I know)

Getting to Six Paths rewards you with 12 arena rank points right? So all you have to do is rake some points until you get to 47 arena points then receive the arena mail (the one containing the ninja frags and arena points). *, instant Six Paths. So what if you failed to reach Six Paths on the previous month? Then adjust accordingly. 50 points if you only reached Super Kage, 51 for Kage, etc. (do the math). I think its really helpful since going to Six Paths from Super Kage is the hardest. Do know that you only have 15 days to do this since the mail expires within 15 days. You can still do this on the last 2 weeks of the month though but only if you don't open your arena interface on the previous days since opening it will immediately give you your arena rewards for the month.
