Remember Rule One

A Class Skill of the Wandering Monk Class, Remember Rule One is a passive skill (requires no Mana to activate, is always in effect) which allows a Wandering Monk to damage any opponent with their preferred weapon, even if the target would normally be too heavily armored or resistant to that weapon's damage type to actually be harmed by it. Anthony, a member of James' Party, is able to do major damage to a monster even though his weapon shouldn't even be able to penetrate its hide.

"Remember Rule One" is a tribute to a similar principle in Sir Terry Pratchett's "Discworld" books. In those books, "Rule One" of dealing with combat opponents is: "Do not act incautiously when confronting a little bald wrinkly smiling man". (Due to the Disc's narrative causality such a person is almost always a highly-trained martial artist.) Here, Anthony looks like a punk kid with a sharp stick: believing that he's harmless because he hasn't got a gun or a sword is a very bad assumption to make.
