Adaptive Fighting
Blademaster Specialist: 3rd level You've learned to make adaptations to your fighting style on the fly. You have three such effects: Change Up, Draw, and Stow. When you use your Adaptive Fighting, you choose which effect to create. You can use this feature twice. You gain an additional use at 5th, 9th, 13th, and 17th level. You regain all expended uses when you complete a short or long rest.
Change Up
You can use your object interaction and expend a use of your Adaptive Fighting to change the Fighting Style option granted to you by your fighter class feature.
Draw
When you use your object interaction to draw one or more weapons, you can expend a use of your Adaptive Fighting (no action required) to increase your critical hit range by 1 with the weapon(s) until the start of your next turn.
Stow
When you use your object interaction to stow a weapon, you can expend a use of your Adaptive Fighting (no action required) to take the Disengage action.
