I have a player who want to play a shaman. He really wants to keep the bard classes but he is much more interested in the druid lore. He doesn't want to be charismatic and handle social interaction, he wants to focus it's music around nature and worship nature-related deities. Therefore he was asking if he can have a bard with wisdom as the incantation characteristic.
I'm about to say yes, but I'm new and I don't know if there is major balance issues that will come up and that I didn't foresee.
