Gunslinger's Trance

As long as you have not used this feature in the previous round of combat, and you are using a one-handed firearm, you can use a bonus action to ready your attack. You can fire multiple separate shots out of your gun at once, as long as the firearm has that many rounds loaded. For each shot you intend to make, roll an attack with disadvantage, and add a misfire score of +3 to every shot fired to your gun's base misfire. You can use this feature for a number of times equal to your proficiency bonus. This ability's uses are reset after each short/long res
