There's some...thing...somewhere with an anti-gravity gun. I'm racking my brains but I can't for the life of me remember what it was. There's also Reverse Gravity spells in a few games/universes...playing with gravity is fuuuuun.

The perpetual lightening strike sounds like some kind of horrible weapon of doom that could be self-powering - if it's messing up weather patterns and the local electromagnetic fields while drawing down a constant stream of power, it could just keep going indefinitely or until there was some catastrophic overload. At this point one wonders what all the built up charge, displaced air and other weather-y things would do...I can't imagine it would be good for those nearby....
