Looks good Sharnid. Just keep in mind that you won't necessarily be able to influence other people's characters or any important NPCs that may pop up with your music ability. You can suggest things that a character might feel, but the end result is up to the players.

Edit: And Forsythe, looks good. I'm just going to nitpick and say change "blinded for a few minutes" to "several seconds." Even 10 seconds is a long time to be blinded. If you don't believe me, hit a punching bag for ten seconds and imagine how much damage that would do lol.
