Samurai's Oath

You have practiced techniques useful in combat against oponents wielding firearms while you are only equipped with traditional weapons, gaining the following benefits:

• Your Strength or Dexterity score increases by 1, to a maximum of 20.
• When a creature makes an attack roll against you with a firearm, you can use your reaction to immediately move up to your full movement towards that creature.
• When you hit a creature within an attack using a weapon that is not a firearm or gadget, that creature suffers disadvantage on the next attack roll it makes with a firearm before the end of its next turn.
