/*
    User takes an amount of Constituation damage.
    In exchange, all allies in short radius are
    healed by their HD * ConDam / 2 and are
    cured of diseases.

    The constitution damage cannot be healed for an
    hour, so it is applied to hide for that duration.
    Once the hour has run out, the damage is applied
    as a temporary effect.
    Also, Stigmata cannot be used again during this
    hour.
