1) As a Jonin medal holder I was able to invite 3 ninja from day one. My bond level is now 69 and I am still only able to invite 3. Day two I had 5 ninja total show up at my home, day three 7 ninja and today 11 ninja. The number of ninja that show up at your home is related to the ninja refreshes on beloved Ero Sennin's screen, when you mouse over your level you can see all your stats.

I do not really understand this part... So number of ninja that show up depends on the ninja refreshes? what is that? thanks :)
