How to make your voice sound old (Decard Cain)

Hey all,

I am trying to make my voice sound like an old wizard. (think Decard Cain from Diablo series).

Any help would be very much appreciated!

There is no “mimicry” effect. That is a human skill (and some animals).
If you can’t impersonate an old man voice you will need to find someone that can (do you know any friendly old people?)
