Dances

Dances are divided into three categories: Sambas, Waltzes, and Jigs. Each of the dances within these categories is acquired at a different level, and requires a certain amount of TP to use. Each category has its own recast time, and using a dance will prevent the use of other dances within the same category until the recast time has expired. In addition, the effect of a Samba dance will be overwritten by other dances within the Samba category, regardless of the remaining duration.

• Sambas imbue melee attacks with special enhancements. Dancer must be engaged and meleeing to grant effect (tested and proven with Drain Samba). Also, the effects are limited to playable characters, pets are not included in this effect. The effect from a Samba is an Additional Effect, and as such Additional Effects from a user's weapon will take priority(Tested with Blind Knife and also with Hellfire Sword). En- effects such as Enthunder will also override a Samba's effect.
  
• Waltzes cure and remove ailments from party members.
  
• Jigs require no TP to use.

Steps & Flourishes

Steps are used to enfeeble an enemy, while at the same time generating the Finishing Moves required to perform Flourishes. Steps require TP to use, in the same manner as dances. The enfeebling effects produced by Steps can be stacked up to five times. The more times an effect is stacked, the more powerful it becomes. Finishing moves are generated at a different rate depending on whether dancer is set as your main job or support job. Up to a maximum of five finishing moves can be stored at one time.
Flourishes are used to produce various powerful effects by consuming the finishing moves generated by Steps. Each type of Flourish requires a certain number of finishing moves to perform. Flourishes are divided into two categories: Flourishes I and Flourishes II. You cannot use Flourishes II unless Dancer is set as Main Job. Each category has its own recast time, and using a Flourish will prevent the use of other Flourishes within the same category until the recast time has expired.
Building towards a Flourish: Build TP with weapon attacks until a Step can be used -> Earn finishing moves by using Steps -> Consume finishing moves to perform a Flourish
