Flash Bear

Named for its resemblance to a bear and its ability to create a blinding flash of light (via mana stored in its paws and the Flash spell), the flash bear is a solitary creature, active at all hours in cave complexes or at night when it emerges to find prey. It is capable of hauling off a human-sized victim, which it grasps and carries with its manlike hands.
It usually lies in ambush around the corner of a tunnel or near a game trail. When suitable prey comes along, it will leap out and flash a brilliant light. It will then grab its blinded victim and dispatch it with its teeth. It will not hesitate to attack solitary humans. Larger parties will be left alone unless the flash bear is threatened or desperately hungry. If it does attack a party, it will grab its victim and escape before dispatching him. It will often have a cubby-hole nearby - most blinded adventurers will stumble right on past. It will be satisfied with one victim, and not bother the rest of the group.
