Laser Swordmaster

You are a trained and practiced sage of the laser sword, a subtle, yet elegant weapon. As such, you gain the following benefits:

• When you are wielding an antimatter dagger, laser halfsword, or laser sword with which you are proficient and another creature hits you with a ranged blaster attack or an attack from one of these weapons, you can use your reaction to add your proficiency bonus to your AC for that attack, potentially causing the attack to miss you.

• You score critical hits on rolls of 19 and 20.
