Going dark with it: How much are organs worth on the black market?
Keeping it light: like 4 or 5 maybe, as long as there is no degradation in capabilities I think I could feasibly let 1 do my job, then the rest and myself could pursue other intellectual endeavors. I would also always have a full D&D group and be able to play the multiplayer games I have always wanted to that never had the interest of my friends.
I always play wildly different characters in my campaigns and like to mix things up. The other players knowing what I am thinking just means that I don't have to communicate my hair brained schemes.
