Player's Handbook[]
The character knows many styles and varieties of dance, from folk dances to formal court balls.
Player's Option: Skills & Powers[]
The character knows and can perform the moves of many types of dances, including some that involve precise and detailed steps. All dances common to the character's society will be familiar. Rare, archaic, or unusual dances will be known with a proficiency check. Also, characters who have had a chance to observe an unknown dance can perform it (–2 modifier, +1 for each time after the first that it is seen performed).
Truly spectacular dances—the kind that win character's campaign-wide acclaim—combine elements of dance proficiency with skills of tumbling, tightrope walking, and jumping.
The Complete Barbarian's Handbook[]
A barbarian with this proficiency knows the ceremonial and recreational dances associated with his homeland. Such dances may be augmented with hoops, sticks, rattles, and other objects that enhance both the complexity and aesthetic quality of the performances.
