Your AC while unarmored is 10 + your Constitution modifier + your proficiency bonus

You have proficiency on Persuasion skill.

You don't need to drink, but you can if you want to. You have half the food requirements for a small sized creature.

If you are in a wet ambiance, get doused with at least 1 pint of any liquid or drink more than a pint of liquid you have disadvantage in saving throws, attack rolls or skill checks depending on Strength, Dexterity or Constitution until you stay in a hot, dry place for at least 1 hour. If you are under rain with no waterproof cover, you gain 1 exhaustion level every 15 minutes if it is light rain, every 10 minutes if it is normal and every 5 minutes if it is heavy rain. If you get submerged or thrown in bodies of liquid, you must immediately make a Constitution saving throw with DC = 10 + turns in the water (Minimum 1). You must roll a new Constitution saving throw at the beginning of each of the turns you spend in the water. In a failed save, you fall unconscious and your life points immediately drop to 0. You don't roll death saves unless you start your turn out of the water. After 5 turns unconscious and in the water, you die. If you get out of the water without a failed save, you gain 3 levels of exhaustion. You can only recover exhaustion levels if you stay in a hot, dry place for 2 hours per exhaustion level and you get a long rest.
