Dancer

Lithe and agile, a dancer trains to gain complete mastery over their movements.  Your precise control over your body allows you to weave in and out of danger on the battlefield and lets you perform physical feats that are beyond those of other creatures.

Performer

At 3rd level, you gain proficiency in the Performance skill if you don't already have it.

Graceful Movement

At 3rd level, while you are not wearing any armor and are not wielding a shield, your Armor Class equals 10 + your Dexterity modifier + one half your Charisma modifier.

Also, as a bonus action you may make a Charisma (Performance) check against an adjacent creature you can see that isn't incapacitated, contested by the target's Wisdom (Insight) check.  If you succeed, the target becomes Charmed by you.  This benefit lasts until the start of your next turn.

Dance Magic

Starting at 9th level you've learned to weave ideas and instructions into your dance, subtly manipulating those that watch it.  You can cast the Suggestion spell without using a spell slot, verbal components, or material components, but it gains a somatic component.  The spell lasts for its duration, requires no concentration, and may target a number of creatures up to your Charisma modifier.  Charisma is your spellcasting ability for this spell and you use your Charisma when setting the saving throw DC of it.

Spell save DC = 8 + your proficiency bonus + your Charisma modifier

Once you use this feature, you can't use it again until you finish a long rest.

Centered Balance

Starting at 13th level you take no penalties while balancing or squeezing and can enter hostile creatures' spaces regardless of their size and their spaces are not difficult terrain for you.

Uncanny Dance

At 17th level your grace and mastery of movement in battle allows you to mislead the movements those who would attack you, placing others in harm's way.  When you use your Uncanny Dodge feature to halve an attack's damage against you, you may have an adjacent creature take the same amount of damage you take.
