Infusion Amplification

As a bonus action, you can sacrifice one of your currently infused items to empower your weapon attacks for 1 hour. This increases the damage of all your weapon attacks by 2d6 force damage. 

Furthermore, if you choose to sacrifice 3 infused items, the damage increases to 4d6 force damage. And if you sacrifice 6 infused items, the damage further increases to 6d6 force damage.

You can use this ability once every long rest.
