A master once said to his pupil that, in the hands of a skilled practitioner, even a parasol can become a deadly weapon. Returning the next day, the pupil excitedly turned over a parasol forged out of metal slats, explaining that it lowered the amount of skill one would need to exert deadly force. The master sighed, seeing that his pupil had failed to see the point, but accepted the gift nonetheless. Ingenuity was, after all, a virtue.
Since then, other smiths have imitated the pupil’s design and crafted additional sensei’s parasols, and they’re highly sought after by those who appreciate multipurpose tools. This weapon functions as a
+2 striking bo staff.
