I apologize if this has been posted before, but I was searching and couldn't find it anywhere. I read much about breakable walls, and the ability to break walls with a weapon. Well, the wall which hides Logan in Sen's Fortress does not need to be broken by redirecting the ball. The sleeping serpent man can break that wall with his sword if you direct his attack towards it. I have tested it, and it works every time. Just something to think over.
Again, if this has been posted before, sorry.
