Well... I don't know if my instructors would agree, but I believe that the true essence of spell development is figuring out how to do all kinds of things in roundabout ways. Once you've designed a technique that can somehow accomplish what you intended, no matter how unwieldy, laughable, or inefficient... you're already most of the way there.

That said, I cannot really recommend putting any particular effort into devising a way to electrocute oneself.

And of course, I can also grant wishes such as "I wish to set something on fire," "I wish a great wind would lift me into the air," and "I wish to obliterate something down to its component particles."
