bladesong

Starting at 2nd level, 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 can use this feature twice. You regain all expended uses of it when you finish a short or long rest.
