Lord of the Dance (3.5e Feat)
From D&D Wiki
Lord of the Dance [Spelltouched]
The urge to dance lingers on you.
Prerequisite: Must have been exposed to irresistible dance spell
Benefit: You gain a +2 competence bonus to Perform (dance) checks that stacks with Skill Focus. If you are ever hit by irresistible dance again, you are still compelled to dance, but you mastered dancing well enough so you don't suffer a penalty to AC and you can make Reflex saves normally. You can even try to make an attack while under the spells effect, but still suffer a -4 penalty.
