Very nice. I really hope you rename the final event, though.... MurdER PreventER: Cup-BearER
(emphasis mine) makes it sound really weird. Or perhaps it's less the repetitive ER and more the word Preventer used in this way that sounds odd. Either way, I think a better title would be good. Otherwise, very nice.
RE: "Hitting the books" -- As an American myself, I clearly understand the phrase and it's common here, but if it isn't common throughout the English-speaking world, which it probably isn't, then it's best to use a phrase that can be understood throughout the world. We don't need players asking "Why would beating books help?"
