It makes a lot more sense (and makes them considerably less O.P) if they simply increasing the force of Kanitah's movements by three times what they actually are. Sort of like having a warhammer attached to your limbs, the warhammer makes a fairly powerful human movement into something far more devastating by increasing the pressure of the movement and the weight of the object you're hitting something with.

If they can reflect any force against them then 1. you should have easily beaten Fury in our first fight 2. this fight has become about 5x harder for me.
