The heartfire fanner (Dragon #314) mentions
the heartfire fanner gains the bardic music ability as a 5th-level bard if he did not already have it
A heartfire fanner’s class levels stack with any bard levels for all bardic music calculations, including the number of uses of bardic music available per day.
How many uses does the Bard 0/Heartfire Fanner 1 get? 1 or 6?
