    Enchantment (Compulsion) [Mind-Affecting]
    Level: Brd 1, Sor/Wiz 1
    Components: V, S
    Casting Time: 1 round
    Range: Close (8M)
    Area: Several living enemy creatures in a 5M-radius sphere
    Duration: 2d4 rounds (D)
    Saving Throw: Will negates
    Spell Resistance: Yes

    Your gestures and droning incantation fascinate nearby creatures, causing
    them to stop and stare blankly at you. In addition, you can use their rapt
    attention to make your suggestions and requests seem more plausible. Roll
    2d4 to see how many total Hit Dice of creatures you affect. Creatures with
    fewer HD are affected before creatures with more HD. Only creatures that can
    see or hear you are affected, but they do not need to understand you to be
    fascinated.

    If you use this spell in combat, each target gains a +2 bonus on its saving
    throw.
//:://////////////////////////////////////////////
//:: Spell Effects Applied / Notes
//:://////////////////////////////////////////////
    Uses confusion effect.

    This will, in the confusion heartbeat, make them face the effect creator :-)

    Similar to sleep otherwise, and the +2 saving throw is true if the caster
    is in combat.
