31 The werechameleon situation was resolved surprisingly quickly, with only one casualty (that I'm aware of, at least). My ad hoc militia didn't have nearly enough time to assemble and grab their crossbows and quivers, but apparently somebody managed to kill pretty quick.
It killed my brewer (not a big loss), and may have bitten and infected an unknown number of dwarves before being killed. I haven't had any dwarves turn into lizards and go berserk yet, but I'm not sure if I've let the simulation run for a month after that incident yet either.
