Danse of the Crescent Moon

Inspired by your faith in the Dark Maiden, you enter a trance like state that let you wield blades and magic  into a graceful and deadly dance. Until the spell ends, you gain the following benefits:

• Your movement speed increase by 10 feet and does not provoke attack of opportunity.
• You have proficiency with longswords.
• You have advantage on attack rolls that you make with longswords.
• When you hit a target with a weapon attack, that target takes an extra 2d12 Radiant damage.
• Longswords you wield gain the finesse property and shed bright light in a 30-foot radius and dim light for an additional 30 feet. If any of this spell light's area overlaps with an area of darkness created by a spell of 3rd level or lower, the spell that created the darkness is dispelled.
• You have proficiency in Dexterity and Constitution saving throws.
• You have proficiency in the Acrobatics and Performance skills. Your proficiency bonus is doubled for any ability check you make that uses either of those skills.
• When you cast a spell, including this one, using an action on your turn, you can make a melee attack as a bonus action.
• Your armor and clothes take the form of a very light silk gown and your shield takes the form of a light silk scarf. They still provide the same Armor class or magical properties but their weights are reduced to 1 lbs and you do not suffer their encumbrance. 
• As a reaction, which you can take when you are hit by an attack,  you can roll an Acrobatics or a Perfomance check, if your is roll higher than the result of the attack, the attack miss instead.

If you move less than half your movement until the end of your turn or if you end your turn in the same space that you beginned your turn, the spell ends.

Immediately after the spell ends, you must succeed on a DC 15 Constitution saving throw or suffer one level of exhaustion.
