Turbine's official Dungeons & Dragons Online website has been updated with a sixth monster profile, this time detailing the Hill Giant. Once again, concept art of the creature is included, but you'll need to be a member of the game's forums to view the article. An excerpt:
Should close-ranged attacks fail, the hill giant relies on his practice of rockthrowing to send discouragement to more distant enemies. The giant carries an ample supply in its home environment, but do not place it beyond the strength of this titan to reach down into the soil and pick up large stones at a whim. About the only weakness commonly known to these large thuglike creatures lies in their relatively unarmored hide (low Armor Class) and their simplemindedness (poor Will saves).
