Coated Strike. Whenever you finish a long rest, you can create a number of volatile substance vials equal to your proficiency bonus. When you creating the vial, choose acid, fire, or poison vials. As a bonus action, you can expend a vial to coat a weapon or three pieces of ammunition you are holding. Alternatively, you can use an action to apply it to a weapon or ammunition held by another creature within 5 feet of you. For 1 minute, or until the weapon is no longer being held, attacks deal an extra 1d6 damage of the chosen type. Vials are consumed upon use, and unused vials lose their potency at the end of your next long rest.
