Autistic Hyperfocus

You are exceptionally focused on your current interest, to the detriment of others.

At the end of each long rest, you may roll a d20. If you roll a 19 or 20, reroll. Using that number, count up on the character sheet from the first skill (athletics) to the last skill (survival) until the rolled number is reached. This skill is marked as your current hyperfocus. Until the next long rest, you gain proficiency in this skill. If you already have proficiency in this skill, you gain expertise. If you already have expertise, you may roll every skill check related to this skill with advantage.

As a consequence, every other skill check besides this one will receive a -1 penalty.
