Inspired Strike

You are able to tap into moments of pure inspiration, during which you are more capable of striking down your foes than ever before. While you have Inspiration, you gain the following benefits:
-you gain +1 to weapon attack rolls

-when you hit a target with a weapon attack, you may spend your Inspiration and immediately add 2d6 to the weapon damage dice dealt by that attack. This damage improves to 3d6 at 12th level, and 4d6 at 17th level.

Additionally, at your DM's discretion, if you spend 8 uninterrupted hours in martial training exercises, you may restore your Inspiration.
