I'd imagine this is not the final boss fight for the second mansion area, but nevertheless this battle is difficult. Three different ghosts show up, each one carrying a mirror. Whenever flashing Luigi's light at either of the ghosts, all they seem to do is deflect the beam and then pummel Luigi afterward.
Is there anything that can be done here? I've also tried vacuuming away the mirror first, which has no effect.
How the hell could u not see them dropping there mirror from there face from time to time. But anyway yea I had trouble when trying to.suck them up cause I didn't know u could dodge with B at that point.
