A Quill-Bear looks like a large bear with long, razor-sharp spikes covering its back and sides. This ursine creature is as massive as a typical brown bear, weighing more than 1,800 pounds and standing about 9 feet when it rears up on its hind legs.

As with other bears, a successful hit by both claws on the same opponent in a given round means that opponent has automatically been hugged and suffers the listed additional damage.

The quills of a quill-bear move as it moves, waving and shaking. Any creatures within 5 feet of a quill-bear as it walks or runs suffers 1d8 points of damage; a successful save vs. Death Ray is allowed to avoid this damage. However, anyone who attacks a quill-bear with a melee weapon (except for a pole arm or spear) must come within range of the spikes and thus suffers 1d8 points of damage automatically with no saving throw allowed.

The quill-bear is normally a cowardly creature (hence the first given morale score) and avoids large groups of potential enemies. Most of the time one lives a solitary life, foraging for nuts and berries and sometimes carrion in the forest. During a full moon a quill-bear’s behavior changes quite dramatically, becoming aggressive and bloodthirsty; use the morale score in parenthesis at such a time. During the full moon the creature’s diet becomes entirely carnivorous, with a marked preference for larger prey such as horses and humanoid creatures, and the quill-bear will seek them out deliberately. This change in behavior applies both day and night during a full moon, even if the moon cannot be seen; however, as the quill-bear is nocturnal, one will not normally be encountered hunting in the daylight.

When under the light of a full moon, the quill-bear grows larger and gains a hit die; treat the extra hit points thus gained in a fashion similar to a potion of heroism. While exposed to moonlight, a common quill-bear will regenerate damage at a rate of 2 hit points per round, while the huge variety regenerates 3 hit points per round. If the creature is killed but its body is left in moonlight, there is a 60% chance that the bear will arise again in 2d4 rounds with half of its hit points restored.
