/*
    You create a lingering decay in the spirit and
    body of the target. If the target fails its saving
    throw, it takes 1 point of temporary Constitution
    damage each round while the spell lasts (maximum
    5 points of Constitution). If it makes its save,
    it does not lose any Constitution but take 1d2
    points of damage each round while the spell
    lasts (maximum 5).

    31.12 - Updated to reflect new scirpting.
    See melf's acid arrow for details.
