As a free action, you can spend one point of Inspiration to attempt an addition. You gain advantage on your first attack roll.

You deal bonus damage equal to the number of consecutive hits you land. The extra effects you can attempt are listed below:

6 Hits: Throw one magic attack item at an enemy within 30ft.
