Playing around with a build for a PC.
She wields a normal rapier that has been upgraded with a steampunk features - it spits off crackling electricity.
I'm thinking a NND Blast (defense is insulation, grounding, and magic).
However, I'm not sure how to build the Charges/Battery, and how easily the Focus is disabled. The PC has a battery that is worn on the belt that feeds power into the sword - she uses a hand crank to recharge it.
So the battery represents a target, as well as the cord attaching it - the sword would still work, but one could disable the electrical aspects of it by attacking either one. So perhaps a Bulky Foci? Or perhaps it's just SFX of OAF.
I'm also not sure how to handle the on/off aspect of it. If you get hit with the sword, then the Blast should hit you automatically. However, you should be able to just shock someone without stabbing them- just hit them with the flat of the blade.
I'm also looking at an Endurance Reserve. Essentially I want to be able to achieve the effect that the PC might have to pause in combat to awkwardly turn the hand crank to charge up the sword again.
