You have gained an attunement with the flow of ki, the magic that runs through all living things, in your own body, and can bend it to your will to an extent.

You have 2 ki points, which you regain after you finish a short or long rest. You can spend them (and ki points gained from levels in the Monk class) to create the following magical effects:

Focused Strike. When making an attack, you can spend a ki point to make the attack count as magical for the purposes of overcoming resistance and immunity to nonmagical damage. The attack deals additional damage equal to your proficiency bonus.

Tranquility. You can spend a ki point at the start of your turn to ignore any effect that would limit the actions you could take on your turn, such as the Gibbering ability of a gibbering mouther or the confusion spell.

Swiftness of Action. You can spend 2 ki points to gain either an additional free object interaction or an additional bonus action on your turn.
