Yes! It turned me into a human and I'm not the only one. I've even heard that it can turn robots into humans as well.

And even if you are already human before coming here, if you got any sort of magic or abilities, it'll take those too.

[Fortunately, all of Riz's abilities are just rogue stuff and not dependent on magic (just the element of surprise, bitch) though it is pretty hard to use any of that stuff without his gun.]
