Compelling Performance, Improved (Feat)

The creature's uncontrollable dancing is unceasing, exhausting it to near-death.

Prerequisites: Level 16, Compelling Performance (Feat), Harmony class feature

Benefit: If a single target suffers the effects of Harmony over two consecutive rounds, it must make a Fort save, DC 10 + half the bard's level + CHA mod, or become Fatigued. If the same target suffers the effects of Harmony on a third consecutive round and is already fatigued, they must make a second save, with the same DC, or become Exhausted.
