Hello forum member awhile ago I heard of a bow that was made for bards it let you change a round of bardic performance into some damage dice or something similar was wondering if anyone knows of it and could provide a link thanks!
Good news! You don't even need a new bow, just a new bow string. Well, it doesn't add extra damage, but it's awesome for bards. Probably not really what you were looking for though.
Not what I was looking for but still an awsome item!
You're probably looking for something from 3.5e. There was a bow that let you add cha to hit & damage either for one shot, or for one round, can't remember, in return for a bardic music use(you had a lot fewer of those, was still a fairly bad item).
Also, there was a rapier that dealt extra sonic damage when you were singing.
Now we have (at 11th level) Discordant Voice, which allows all party weapons (including the Bard's bow) do an additional 1d6 sonic damage with each attack.
