I am creating a bard for my first ever DnD session (3.5e) with my friends and I had a question about the subcategories in the Perform skill being able to stack or not. Like, if my bard has Perform String Instrument, Perform Sing, and Perform Storytelling and I go to make my check for a performance, can I roll all three of those modifiers for playing the instrument, my amazing singing voice, and the lyrics in the song conveying the tale? If so, a lot of the bard spells require a certain number in performance (3 for first level). If I put a single point into those three performances to play my music (using them in the manner as above), does that count as the 3 points needed to cast said spells?
I have never played DnD before and I can't find anything regarding this on the internet. I sent a message to the person who is suppose to be the DM of our campaign, but I figured I would post my question here as well.
