Changes

: - These new skills only go to level 10 for now. That's high enough to unlock all six existing tracks for the instrument.

: - People who listen to a performance (including the performers) gain a minor buff called Performance Appreciation, which boosts earned XP and out-of-combat armor regeneration. The effect is highly dependent on the number of performers, their skill level, and the diversity of the performance (more instrument types = very beneficial!). It can vary from +1% XP to +14% XP, and from +4 to +56 armor regen.

: - The longer you listen to the performance, the longer the buff lasts. (Again, the formula is based on the number of performers, their skill levels, and the instrument diversity.)
