- Attribute: Influence
- Type: Utility
- Time: Two actions
- Description: Characters with this skill are able to mix instrumentals and vocals to create a dynamic tune that can affect enemies or allies in combat. With a successful skill check, the character is able to play a song that has the emotional power to offer specific modifiers, based on the number of skill points in Performance. There are six possible "songs" that are available, each of which can be played in a host of different ways, using a variety of instruments and/or vocals; the character can choose any two to learn after acquiring the skill. After the initial skill check, the character can play a song for an additional round per two skill points in Performance; a minimum of two actions must be spent playing the song, the two remaining actions may be used to move or defend, but any attack action breaks the rhythm and ends the song. There is a progressive difficult (-4) modifier to recapture that emotional power after each time a song is played in an encounter. If the skill check fails, the modifiers are not applied, and each additional attempt carries the progressive difficult (-4) modifier as stated above.
