/*
    Long range area of effect spell
    10d6 sonic, acid, fire and lightning damage to all
    objects in the area

    10d6 points of negative energy damage to caster
    if MODULE_SWITCH_EPIC_SPELLS_HURT_CASTER switch
    was enabled on the module.

    This spell is supposed to hurt the caster if he
    is stupid enough to stand in the area of effect
    when all hell breaks loose. It will hurt other
    players allied with the caster as well. These
    effects are dependent on your difficulty setting

    Save is 20 + relevant ability score, or, when cast
    by a placeable, equal to the placeables WILL Save

    There is no benefit from the evasion feats here
    as the are of the spell is too large to avoid it
