I've mulled over the Versatile Performance problem. While mulling, I was reminded of the words of Ludwig von Beethoven.
Music is a higher revelation than all wisdom and philosophy.
The bard, through his study of music and other entertaining arts, gradually arrives at deeper, intuitive understanding of certain things. This almost mystical understanding manifests itself through the bard's Versatile Performance class feature. Note that Versatile Performance doesn't mean a bard is using Perform to actually do the skill. For example, a bard with Versatile Performance for Perform (keyboard instruments) isn't actually more diplomatic or intimidating because he's playing a piano. Rather, his bardic understanding of the metaphysics of keyboard music makes him more diplomatic and more intimidating.
A New Type of Versatile Performance (Ex)
At 2nd level, a bard can choose one type of Perform skill. At 6th level, and every 4 levels thereafter, the bard can select an additional type of Perform to substitute. Each type of Perform skill has two other skills associated with it: Act (Bluff, Disguise), Comedy (Bluff, Intimidate), Dance (Acrobatics, Fly), Keyboard Instruments (Diplomacy, Intimidate), Oratory (Diplomacy, Sense Motive), Percussion (Handle Animal, Intimidate), Sing (Bluff, Sense Motive), String (Bluff, Diplomacy), and Wind (Diplomacy, Handle Animal).
The first time one of these skills is affected by Versatile Performance, the bard gains a bonus skill point for those skills only. For example, at 2nd level, a bard chooses Oratory as his Versatile Performance. He gains 1 bonus skill point in Diplomacy and 1 bonus skill point in Sense Motive.
Every subsequent selection of Versatile Performance only awards a bonus skill point if that particular associated skill has not already received a bonus skill point. Otherwise, the bard receives a +2 insight bonus with the skill. For example, at 6th level, our bard chooses Sing as his second Versatile Performance. He receives 1 bonus skill point in Bluff since this is the first time it has been an associated skill for Versatile Performance. He receives a +2 insight bonus to Diplomacy since it's already received a bonus skill point.
The third and greater times a skill is associated with Versatile Performance, the insight bonus increases by +2. For example, at 6th level, our bard chooses Keyboard Instruments for his next Versatile Performance. He gains 1 bonus skill point in Intimidate. His insight bonus to Diplomacy increases to +4.
Is this a good start to "fixing" Versatile Performance? If not, why not? What're your ideas and suggestions?
