I am trying to cast a spell, like Message which requires "pointing" at the target, but without looking directly a the target.
I think there are two possible situations that could occur:
- As suggested by Thomas Markov, the mirror is the only way you can see the target with no other direct line of sight. I would have to point into the mirror at the target.
- I am looking into the mirror at the target, but I can point directly a the target. I would have to do a "trick shot" behind the back at the target while looking into the mirror.
