I've been watching this, http://video.pbs.org/program/uranium...-dragons-tail/

And it struck me. Firstly, if Redcloak made a Uranium elemental, it wouldn't be 235, because that's REALLY rare, but rather 238.

Also, it would shoot energy from itself, but each it does it, it turns into another elemental. And some of those elementals would be gasseus. It would have 26 shots until it became a significantly smaller and stable lead elemental.

Details here, https://en.wikipedia.org/wiki/Uraniu...nium_series.29

You'll notice that there are several radioactive isotopes of lead in this series.
