  Effects:  The Jump skill has only this one, singular use:
   * Jumping (Active): Use this skill to cross from one square to another in the dungeon while missing a square in between. This skill will let you get past a monster without bull-rushing it, or to avoid a trap or pit. Beware, though -- if you try to jump too far, you may not end up where you want! A typical jumping DC is 15 for 1 square, +5 per extra square! Jumping provokes an attack of opportunity.
