You can inspire actions in multiple allies at once.
Benefit: When you use your bardic music ability to inspire another ally to take an extra move or standard action, you can use up additional uses of bardic music (up to 1 additional use per level of chronicler you possess) to inspire additional allies to take action. Each additional action costs 1 more use of bardic music than the previous action you inspire. For example, inspiring 3 actions at once uses up 6 uses of bardic music: 1 use for the first, 2 for the second, and 3 for the third. You cannot inspire the same ally to take more than 1 additional action: you must choose different allies.
