You can invoke a secret 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 you choose (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 once and you cannot use it again until you have finished a short or long rest.
If you have this ability from another source such as the Bladesinger wizard tradition this feat gives you an extra use of the ability.
