You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight. After 4 hours of being exposed to direct sunlight your ability scores are decreased by 1 point each. After an additional 4 hours, this effect doubles. Ability scores modifed by this trait can be lowered to a minimum of 5 points. You regain lost ability scores after completing a long rest in the shade. If you rest in complete darkness, the time to heal is halved, down to 4 hours.
