Normally, Extraordinary Exponents with the Power of Consecution would need a full night's deep sleep to recover one hundred percent of their Spiritual Power, as their efficiency in recovery during battle was extremely poor.
However, the "Hymn Verse" could allow an Extraordinary Exponent, whose spirituality had been depleted, to recover a certain amount of Spiritual Power every hour. According to Byrne's calculations, this amounted to a recovery of 10 per hour.
The "Bravery Verse" also required the "Bard" to recite it in full for it to take effect, and all allies who listened would receive a buff. Similarly, within a two-hour timeframe, allies would collectively experience an increase in killing power.
Whether on the physical plane or the magical plane, they would all receive a conceptual boost in their attacks.
