School of the Bladesinger {Improved}

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.

Training in War and Song

 

When you adopt this tradition at 2nd level, you gain proficiency with light armor, and you gain proficiency with 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.

Bladesong

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 gain a bonus to your AC equal to your Intelligence modifier (minimum of +1)

• Your walking speed increases by 10 feet.

• You have advantage on Dexterity (Acrobatics) checks.

• You gain a bonus to any Constitution saving throw you make to maintain your concentration on a spell. The bonus equals your Intelligence modifier (minimum of +1).

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.

Magic Knight

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.

You can also perform the somatic components of spells even when you have a weapon in one hand.

When a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to cast a spell at the creature, rather than making an opportunity attack. The spell must have a casting time of 1 action and must target only that creature.

Defensive Dance

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 + your wizard level + your Intelligence modifier. 

 

Arcane Smite

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

In addition, when you hit a creature with a melee weapon attack or cantrip, you can expend one spell slot to deal force damage to the target, in addition to the weapon's or cantrips normal damage. The extra damage is 2d10 for a 1st-level spell slot, plus 1d10 for each spell level higher than 1st, to a maximum of 5d10.
