You break open the door and find yourselves face to face with a very thin, tall man in a wizard's robe. His eyes flashing, he cries out a command in a strange language, and the stuffed Black Bear in the corner, suddenly animated, gets up and attacks you.

[The bear has a Constitution of 50. It gets 6D6+25 adds, and won't quit fighting until it has been literally torn to pieces. In addition, for each combat round when it is not dead/destroyed, it regenerates 5 CON points, even if it isn't hurt. If it's CON gets to 60, then it gets 7D6+30 in combat and so forth everytime it's CON goes up by 10 to the next level.]

If the bear kills you all, then you are DEAD!

But maybe you will beat the bear.
