Bladesong (Int)

As the elven warriors of old, you have been trained in the traditional fighting style 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 gain the following benefits:

• You gain a +2 bonus to your AC.
• You have advantage on Dexterity (Acrobatics) checks.
• The dance of the elven Bladesong is imbued with the power of the weave of magic, as a result, any Magic Weapon you wield you can use Int instead of Strength for the attack and damage rolls with this weapon. 

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).

*The Bladesong fighting style is a traditional elven martial art, this feat would usually only be taught to elves and half-elves, but if the restriction on that tradition is lifted, the race restriction should be lifted at the same time.
