Thank you very much for checking it out! That is meant to be flavour in the title to distinguish why it has a +1 to it's damage. It is not considered a Trait and that +1 always is included in the damage.
I hope not too much time was spent looking! I should think of a way to make that more clear. I am glad you reached out about it. I am always happy to answer any questions. Thanks again. I hope you enjoy your time with the game!
