I initially had this posted in the D&D Deliberations board and was told I might have better luck over here.
I usually play fighter-types, but I'm trying my hand at a bard for a new campaign, so I need help. It's ninth level, and it's short, so there will not be very much, if any, character advancement. I had this idea of taking Leadership and fixing myself up with another bard cohort, and I was wondering if there was a feat out there that would allow multiple bards' abilities to stack as far as determining DC for bard abilities. Does anyone know of a feat/feat tree that would do this? Any and all 3.5/Pathfinder books are fair game.
