Gift of The Magi (Tier One)

Passive: You are naturally attuned to the presence of magic and arcane energies. You can determine if an object is magical just by touching it, and if there is a hidden magical object or creature within 10 ft of you, you can discern its general location.

Active: You can ritually cast a spell that you are familiar with (have cast, seen cast, or have a scroll) with the ritual tag. The spell's level can be up to half your proficiency bonus, rounded up.
