1st degree Razor’s Edge Action
The execution and follow through of your strike is exquisite with not an iota of force wasted.
When you activate this maneuver, you take the Attack action and make a weapon attack, as well as any additional attacks granted by Extra Attack. Until the start of your next turn, your weapon attacks score a critical hit on a roll of 19–20.
If you already have a feature that increases the range of your critical hits, your critical hit range increases by 1 (maximum 17–20).
