Extract Aspects

"Know your enemy."

 After being trained by a Monk Master, you can strike multiple pressure points to extract crucial information about your foe.

Whenever you hit a single creature with one of the attacks granted by your Flurry of Blows, you learn the creature's Damage Vulnerabilities, Damage Resistances, Damage Immunities, and Condition Immunities. Once you use this feature, you must finish a short or long rest before you can use it again.

Progression: Upon reaching 11th level, you can use this feature twice between rests, and beginning at 17th level, you can use it three times between rests. When you finish a short or long rest, you regain your expended uses.

Concept from Monk: Way of the Cobalt Soul
