Please gm can answer my question?

I searched the forum for similar topics but i didn't find any.
I have 2 questions the first one if i buy the premium membership how long does it take the server( or you) to active it, and how can i see that my drop rate is increased? The only way is to kill monsters and hope for a better drop? or is there any other way to check it?
Thank you for your patience and time.

Please someone answer me i really need the answers...

 

If you buy something in the shop it wil be on your account directly.
There isn't a way to see only that the rates are higher.
