    when this skill is used.  If this is zero, then experience only goes to
    to the skill.  Values higher than 1 are allowed.  Note that experience
    rewarded to the players total is in addition to that given to the
    skill.  Eg, if player should get 500 exp for using a skill, and
    expmul is 1, the player will get 500 added to that skill as well as
    500 to their total.</td>
