I told this to the owner before, but it's back again, if you trait respecc and you have all the kido's that you want, or a specific one like let's say black coffin, all you need to do is put in 90 traits in kido and put all the levels you want on it. This is where the glitch comes in, once you respec traits you'll still have that kido even though you have 0 kido in traits, so you shouldn't have that.
