Earning Status Points will also award Guild Status Points, which in turn results in Guild Experience to your guild and helps your guild to level up.
10% of the Status Ppoints you earn will also be awarded as Guild Status Points. If you leave your guild and join another your Guild Status Points reset to zero. Even if you return to your original guild, your Guild Status Points starts again at zero. Your guild does not, however, lose the Guild Experience you earned for them while you were there.
