I'm doing research into this and everything is super unhelpful with 'it's the current that kills not the watts.' Gee thanks but I think it in watts, not damn amps xD (Boo for actually converting it myself)

I'm probably going to go with like 1000-1500?? My view of an extreme use of her power was to kill someone with it, but I'm not sure if that isn't actually extreme or what haha.
