Song of the blade

Bladesingers are trained in a magical tradition that includes swordsmanship and dance. Originally created by elves, this tradition has been adopted by non-elven wizards who honor and spread elven traditions
In combat, the bladesinger performs a series of complex yet elegant maneuvers that prevent potential damage and channel magic into devastating attacks and deft defenses. Many of those who have watched the bladesinger at work recall the sight as one of the most beautiful experiences of their lives - a magnificent dance to the accompaniment of the bladesinger.

War training and song

You gain proficiency in light armor and one type of one-handed melee weapon of your choice
You also gain proficiency in the performance skill if you don't already have it

Song of the blade

You can awaken elven magic called Bladesong if you are not wearing medium or heavy armor and are not using a shield. The song imbues you with uncanny speed, agility, and focus
As a bonus action, you can start a Bladesong that lasts 1 minute. It will end early if you become incapacitated, wear medium or heavy armor, a shield, or use both hands to make a weapon attack. You can also interrupt Bladesong at any time (no action required).

Extra attack

If you take the Attack action on your turn, you can make two attacks instead of one. Additionally, you can cast one of your cantrip instead of one of these attacks.

Song of protection

While your Bladesong lasts, you can use your magic to absorb damage. When you take damage, you can use your reaction to expend one spell slot and reduce the damage you take by five times the level of the spent spell slot
