You call on the knowledge of legends, augmenting a skill for the duration. You gain proficiency in the chosen skill. If you were already proficient, you instead gain expertise (doubling your proficiency bonus for any ability check you make with the skill). If you already have expertise, you can instead reroll one of the dice once whenever you have advantage on that ability check. The spell ends early if you cast it again.
