College of Dance.

The College of Dance is one of the oldest colleges to still practice the bardic arts. There is a wide schism that separates this college from the others. This is due to their performance, which does not rely on song, instruments, or sound at all, but dance.
Bards of this college are often simply referred to as Dancers, but the roles they play are anything but simple. There are Dancers who perform holy dances used in prayer; there are Dancers who tell stories and keep history alive through their performances; and there are those who dance in the very battlefield, mixing performance with combat, lifting the spirits of their companions and allowing them to perform feats beyond their normal capacities. These Bards use dance to become a blur in the enemy’s eyes, dodging their attacks with expert grace and poise and clouding their minds with enchanting movements that make the Dancer harder to pin down.
It takes courage to stand in the thick of battle among armed warriors and armoured Paladins, but it takes a Bard to do so while dancing.

Level 3 Features:

Somatic Performance.

You are able to cast your magic using only the precise, meticulous, and elegant movements of your body. You may choose to replace all Verbal or Material components of a spell with only the Somatic component of dancing, so long as the material components of the spell do not have a cost.

Dance.

You can perform an arcane dance that empowers and inspires an ally in combat. As a Bonus Action, you can start your Dance and choose one creature you can see within 15 feet of you. Roll your Bardic Inspiration die. That creature can now add the result of your Bardic Inspiration roll to one ability check, attack roll, or saving throw per round. On the next turn, the creature you inspired can add your Bardic Inspiration roll again, so long as it remains within 15 feet of you and you keep dancing. The Bardic Inspiration bonus decreases by one at the end of each of your turns.
For instance: You use your Bonus Action to start your Dance and select an ally within 15 feet of you. You roll a 6 on your Bardic Inspiration die. The creature you’re inspiring attacks an enemy and adds +6 to their attack roll. After the end of your next turn, the creature you’re inspiring now adds +5 to their attack against that enemy. The creature you’re inspiring adds +4 in the next round, then +3, and so on, until the Bardic Inspiration bonus is reduced to 0.
A creature automatically loses all benefits of your Dance when they leave its 15-foot radius.
You can renew the dance by using your Bonus Action to expend another use of your Bardic Inspiration and re-roll your Bardic Inspiration die. You must concentrate on this Dance as if it is a spell, and cannot cast any spells that require Concentration while using this ability.
You can end your Dance at any point during your turn without using an action or Bonus Action.

Level 6 Feature:

Deadly Dance.

Your calculated movements blend dance with battle prowess, allowing you to double your attack prowess while you dance and move across the battlefield seamlessly.
While you’re using your Dance ability, your Speed increases by 10 feet and you can attack twice, instead of once, when you take the Attack action on your turn.

Level 14 Feature:

Danse Macabre.

You have mastered the art of dancing on the battlefield. Your very presence inspires even more combatants to transcend their physical limits in combat, making them even deadlier in turn.
The radius of your Dance ability is now 20 feet. When you use your Dance ability, you may empower two allies simultaneously. Both allies must remain inside the 20-foot radius to receive the benefits of your dance. If one leaves while the other one remains in the area of effect, the one remaining still enjoys the benefits, but you must use a Bonus Action and roll your Bardic Inspiration die if you wish to empower a second ally again. The new roll overrides the previous one.
For instance: The original Bardic Inspiration roll is 8, and you are inspiring two creatures. One creature leaves the radius of your Dance and loses the benefits of the Dance. A new creature enters the radius and you use your Bonus Action to roll your Bardic Inspiration die to inspire that second creature, the result being a 4. Both creatures now add +4 instead of +8 to their ability checks, saving throws, and attacks.
