Shadow Strike

Precision Strikes: Once per turn, when you hit a creature with a weapon attack using a finesse or ranged weapon, you can choose to reroll any damage dice that result in a 1 or 2. You must use the new roll, even if it is another 1 or 2.

Assassin's Expertise: Your sneak attack damage increases by 1d6. This bonus damage increases to 2d6 at 11th level and 3d6 at 17th level.

Executioner's Gambit: When you hit a surprised creature with a weapon attack, you can choose to maximise the damage of the attack, rolling the maximum possible result for all damage dice rolled.
