I need some help when Ron has to defeat some ghosts using the light spell.
shareWhen attacking them with Lumos, try and back them into a corner so they can't escape you. Then when they look solid use Incendio (I think that's the spell, I haven't been on the game for ages).

I agree this is irritating, but stick with it. Hit one of them with Lumos until they turn solid then blast them with flipendo. Make sure to hold down the lumos button until they become solid and keep Ron moving or the other ghosts will burn him.
Good luck!
Merry Christmas ya filthy animal.
Ah, Flipendo, that was it. I knew it ended with an 'o' : P
