5th-level Spell: Skill Empowerment

Aspetheurgy (Transmutation)

You supernaturally deepen a creature’s understanding of its own talent. You touch one willing creature and give it Expertise in one skill of your choice; until the spell ends, the creature doubles its proficiency bonus for ability checks it makes that use the chosen skill.
You must choose a skill in which the target is proficient in and that isn’t already benefiting from Expertise or a similar effect that is doubling its proficiency bonus.
