Description: You invest a little bit of your piety into your every performance.

Prerequisites: Bardic Music ability, Turn or Rebuke Undead ability

Your bard and cleric levels stack for the purpose of determining your turning check and turning damage. For example, a 4th-level bard/1st-level cleric turns or rebukes undead as a 5th-level cleric. Your bard and cleric levels also stack for the purpose of determining the number of times per day you can use your bardic music (although this does not affect which bardic music abilities you can use). For example, a 5th-level bard/4th-level cleric receives a bonus equal to 9 (the sum of his bard and cleric levels) + Intelligence bonus (if any) on his bardic knowledge checks, and he can use bardic music 9 times per day.
