Detect Weakness

You place your hand on a creature, object, structure etc. After a brief moment of contact you are aware of any structural defects in the target within 100 feet. I.e. a rotten support beam, a fractured stone, a bad knee. Any attacks targeting these weak spots have +2 to attack roll.

The attack roll bonus increases by 1 when you reach 5th level (+3), 11th level (+4), and 17th level (+5).
