All the characters in your party will also get a buff that gives them +1 to Strength, Constitution and Intelligence. The bedroll is a consumable and using it will replenish the Health Points of your entire party and both types of armor as well as remove all negative statuses (besides the permanent ones). You will be able to find a free bedroll on the floor of the ship at the beginning of the game and picking it up will not be considered stealing. Make getting these two items your first two priorities when you begin playing Divinity: Original Sin 2.
