/*
    You infest  a target with maggotlike creatures.
    They deal 1d4 points of temporary Constitution
    damage each round. Each round the subject makes
    a new Fortitude save. The spell ends if the
    target succeeds at its saving throw.

    If the targets constitution would drop to 0
    through this spell, and the player is playing
    on hardcore difficulty, the target is
    is killed instantly.
