I don't know anything about lockmastery. Can a lockmaster not only lock something but set a trap on it?


"So, what does that green line on the graph represent?"

"Oh, that's the projection of a hypothetical offspring from a union between Sauron and Cruella de Ville; we use that as a baseline for determining character alignment."

It all depends on what you mean by setting traps. There isn't any trap setting skill as such, but sneaky things can be done which might catch someone else.
