Vision AOU sp1 not dealing any damage?

Just to clarify, I’ve looked all over Reddit and the forum for other posts about this, and have found none. So what would happen around 20-30% of the time I use Vision AOU’s sp1 and no damage is dealt nor any energy taken away. It connects with the opponent and he’s knocked down, but nothing happens. What am I doing wrong?

If no power is burned, no damage will be inflicted.
So it depends who you’re fighting and under what circumstances.
