That makes sense; I just had the vision of cenobites in my mind when thinking about the angels so decided that's something they could look like :). Regarding safety tools, I suppose I could try to include actual safety tools, but I don't feel qualified to come up with my own, and to not do them a disservice would probably take up a whole page at least, so I decided to defer to people who actually know what they're doing, and I assume people can find the right stuff.
