I must have done something wrong with the weapon. For some reason hits just did not register on enemies. The offhand weapon worked fine though. Based on the gif the combat does look quite fun though.

Ah shoot. Yeah, I probably should have explained. The weapon you pick is a test weapon, based off of the tonitrus from Bloodborne. Right Trigger does your attacks, where as Right Bumper charges up the weapon with electricity. You can combo in a Right Bumper as an attack, but otherwise all it does is flick the weapon to electrify it.
