My Maxwell shots never do damage. Why?

From a beta customer:

When I try to attack using the Maxwell, the fireballs never do any damage, am I doing something wrong?

When they do hit, they do big damage and at a long distance, so I’ve tuned it to be very innaccurate. They will hit, just not often!

They also have a range. It could be that you are shooting outside the range. Look at the dark area when you first select the attack to see how far they will go
