    Enchantment (Compulsion) [Mind-Affecting]
    Level: Animal 1, Drd 1, Rgr 1
    Components: V, S
    Casting Time: 1 standard action
    Range: Close (8M)
    Targets: Hostile Animals in a 5M-radius sphere
    Duration: 1 min./level
    Saving Throw: Will negates; see text
    Spell Resistance: Yes

    This spell soothes and quiets animals, rendering them docile and harmless.
    Only ordinary animals (those with Intelligence scores of 3) can be affected
    by this spell. All the subjects must be within a 5M-radius sphere. The
    maximum number of Hit Dice of animals you can affect is equal to 2d4 +
    caster level. A dire animal or an animal trained to attack or guard is
    allowed a saving throw; other animals are not.

    The affected creatures remain where they are and do not attack or flee.
    They are not helpless and defend themselves normally if attacked. Any
    threat breaks the spell on the threatened creatures.
//:://////////////////////////////////////////////
//:: Spell Effects Applied / Notes
//:://////////////////////////////////////////////
    This spell Confuses animals, making them stand still basically (not
    attack or flee).

    However, if they have a valid last hostile actor, they will have this
    effect removed.

    For all "Calming" spells, or those which are broken after being attacked,
    a new hostile actor will apply 1 damage and then heal it (or the other
    way around to not kill it).

    If a creature fails its save, the spell is considered "Friendly" and so the
    last hostile actor isn't then replaced with the caster again.
