For you, the thrill of creating an exciting dish from scratch and crushing goblin skulls with your fist have become one and the same. You've learned that the perfect home for you is no home - living on the road between adventures, making the most savory concoctions you can imagine with what you find along the way. Your food grants you and your allies the following benefits -

• Increase your Constitution or Wisdom score by 1, to a maximum of 20.
• During a Short Rest you can work to prepare a nourishing and filling dish with supplies you've brought or ingredients you've foraged for. You create a meal large enough to feed a number of creatures up to twice your proficiency bonus. Creatures that consume the meal are granted a bonus to Hit Points recovered equal to your proficiency bonus added to each Hit Die spent. 
• One level of exhaustion can be recovered after consuming the meal during a Short Rest. A creature can only benefit from this once until they've completed a Long Rest.
• While a creature is eating any food prepared by you and for up to an hour afterwards, you have advantage on any Charisma check made against them provided they understand the language you speak.
