Tasha's Cauldron of Everything
Bladesingers master a tradition of wizardry that incorporates swordplay and dance. Originally created by elves, this tradition has been adopted by non-elf practitioners, who honor and expand on the elven ways.
In combat, a bladesinger uses a series of intricate, elegant maneuvers that fend off harm and allow the bladesinger to channel magic into devastating attacks and a cunning defense. Many who have observed a bladesinger at work remember the display as one of the more beautiful experiences in their life, a glorious dance accompanied by a singing blade.
2nd-level School of Bladesinging Feature
Beginning when you select this school at 2nd level, the gold and time you must spend to copy a abjuration spell into your spellbook is halved.
2nd-level School of Bladesinging Feature
Starting at 2nd level, you can invoke an elven magic called the Bladesong, provided that you aren't wearing medium or heavy armor or using a shield. It graces you with supernatural speed, agility, and focus.
You can use a bonus action to start the Bladesong, which lasts for 1 minute. It ends early if you are incapacitated, if you don medium or heavy armor or a shield, or if you use two hands to make an attack with a weapon. You can also dismiss the Bladesong at any time (no action required).
While your Bladesong is active, you gain the following benefits:
You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses of it when you finish a long rest.

Starting at 6th level, you can attack twice, instead of once, whenever you take the Attack action on your turn. Moreover, you can cast one of your cantrips in place of one of those attacks.
10th-level School of Bladesinging Feature
Beginning at 10th level, you can direct your magic to absorb damage while your Bladesong is active. When you take damage, you can use your reaction to expend one spell slot and reduce that damage to you by an amount equal to five times the spell slot's level.

Starting at 14th level, you can add your Intelligence modifier (minimum of +1) to the damage of your melee weapon attacks while your Bladesong is active.
