Were-Wolf

A werewolf is a savage predator. In its humanoid form, a werewolf has heightened senses, a fiery temper, and a tendency to eat rare meat. Its wolf form is a fearsome predator, but its hybrid form is more terrifying by far — a furred and well-muscled humanoid body topped by a ravening wolf’s head. A werewolf can wield weapons in hybrid form, though it prefers to tear foes apart with its powerful claws and bite. Most werewolves flee civilized lands not long after becoming afflicted. Those that reject the curse fear what will happen if they remain among their friends and family. Those that embrace the curse fear discovery and the consequences of their murderous acts. In the wild, werewolves form packs that also include wolves and dire wolves.
One of the most ancient and feared of all curses, lycanthropy can transform the most civilized humanoid into a ravening beast. In its natural humanoid form, a creature cursed by lycanthropy appears as its normal self. Over time, however, many lycanthropes acquire features suggestive of their animal form. In that animal form, a lycanthrope resembles a powerful version of a normal animal. On close inspection, its eyes show a faint spark of unnatural intelligence and might glow red in the dark.
Evil lycanthropes hide among normal folk, emerging in animal form at night to spread terror and bloodshed, especially under a full moon. Good lycanthropes are reclusive and uncomfortable around other civilized creatures, often living alone in wilderness areas far from villages and towns.
