Studying someone outside of combat you can discern their class, but not their level of mastery or subclass. You must have interacted with this person for 10 minutes. Roll your casting attribute against their deception, if they fail the roll you are aware of their class.
When using this boon, you must open a ticket. You must screenshot and timestamp its cast, and hold onto it for 72 hours.
You may only use this once every 3 days
