[@Polaris North]: It's very easy NOT to kill someone using it. I haven't fully fleshed out the specifics but there's probably quite simply a way to work things nonlethally, but where someone could be much more seriously injured if things suddenly were to go awry. I guess... think Nanoha or something, if you've seen it, where you can totally do things like this without seriously injuring someone but when things go out of control it can get worse.

[@Caasicam]: As for the perspective matter, um, second person is legitimately kind of confusing to read. ^^; Which I think probably is why it's underused, outside of stuff like CYOAs. You can head to the training room, but the group's dispersing and you'll just run into one of the people leaving most likely.

[@banjoanjo]: There's multiple training rooms.

[@Slendy]: Tattoos are not a ritual device. ^^;
