I shot a kamehameha as MysticKrilln at my friend who was Cell Form 2. He block struggled it against the nearby cliff, you can see the scorch mark in the picture. He wasnt taking damage while being pushed against the ground, and when he ran out of ki he was able to move around and fight normally, but I was still stuck in the block struggle. Even when he died the beam would jump back to him and stay with him while he fought. I was out of ki as you can see and still stuck in the block struggle unable to do anything.
