/** @file prc_cwsm_fright
    A 20th-level Samurais bravery, honor, and
    fighting prowess have become legendary. When
    the samurai draws his blade, opponents within
    30 feet must succeed on a Will save(DC 20 + Cha
    Modifier) or become panicked for 4d6 rounds (if
    they have 4 or fewer Hit Dice) or shaken for 4d6
    rounds (if they have more than 4 Hit Dice, but
    fewer than the Samurai). Creatures with more Hit
    Dice then the Samurai are not affected.
    Any foe that successfully resists the effect
    cannot be affected again by the same samurai's
    frightful presence for 24 hours.

    SRD on panicked:
    A panicked creature must drop anything it holds and
    flee at top speed from the source of its fear, as
    well as any other dangers it encounters, along a
    random path. It can<61>t take any other actions.
    In addition, the creature takes a <20>2 penalty on all
    saving throws, skill checks, and ability checks. If
    cornered, a panicked creature cowers and does not
    attack, typically using the total defense action in
    combat. A panicked creature can use special abilities,
    including spells, to flee; indeed, the creature must
    use such means if they are the only way to escape.

    SRD on shaken:
    A shaken character takes a <20>2 penalty on attack rolls,
    saving throws, skill checks, and ability checks.
