Practice picking locks, making black powder bombs, casting bardic spells (they require some kind of performance, whether singing, dancing, recitation, playing an instrument, etc), avoid the traps, and sneaking up on one another to backstab your classmates. Anyone hit with a Danger Shop weapon will turn a bright clolor to show they were backstabbed. So be on guard, unless you want to end the class bright yellow, or pink, or chartreuse!
