The big revelation was that teeth were not the weapon of choice at all; rather, it appears that the killer used a bag of marbles.
This then makes it obvious why the Hippo League would be involved. They are hungry hungry. Dwarves hoard treasure right? The victim may have had all the marbles, presenting an irresistible target to the hippopotami, who stole his marbles and then bludgeoned him to death with them.
There were a lot of marbles involved, so we should have a bit of a reprieve now. Unfortunately, it won't last long. Marbles are like crack, and soon the hippos will be hungry again.
Luckily, we now have additional skills to combat them. Isaac explained that the purpose of the event was to get people accustomed to the RPS and combat systems. You could say it was something for us to cut our teeth on. Because the troll teeth are diamonds, that should mean we now have a Diamond Cutter. If we have a Diamond Cutter, we should also have a Stone Cold Stunner, since they're both just variations on the 3/4 Turn Neckbreaker. Do you think stunning in this game will work like roleblocking? That would make sense.
Did anyone find any diamond teeth at any of the three locations? If so, we should start planning how to use your new roleblocking skills to maximum effect.
