So does this mean if they allowed the game to run on "full moon days", it would be expected to eventually get a higher score (if the full moon day allowed that through the actual game mechanism)?
When you try to fight a werecreature in animal form it can summon large numbers of animals of its kind to attack you. This can be extremely deadly for a player who is unaware of this ability. An experienced player knows to attack werecreatures only at range or avoid fighting them altogether. However, encountering the werecreature in its human form is much less dangerous unless it's carrying a powerful weapon.
