I would also like to ask if the fast hands bonus as a thief be applicable here, since use object can be a bonus action. Essentially the grapple check meets Aurora's AC but the clasps would be undone anyway.
Fast Hands would be applicable here. ^_^ So she can unclasp as a bonus action.
For the Grapple, go ahead and roll either Athletics or Acrobatics to contest Brutrumukk’s 14 in Athletics.
