    Illusion (Figment, Glamer)
    Level: Brd 5, Luck 6, Sor/Wiz 6, Trickery 6
    Components: S
    Casting Time: 1 standard action
    Range: Close (8M)
    Target/Effect: You/one illusory double
    Duration: 1 round/level (D) and concentration + 3 rounds; see text
    Saving Throw: None or Will disbelief (if interacted with); see text
    Spell Resistance: No

    You become invisible (as improved invisibility, a glamer), and at the same
    time, an illusory double of you (as major image, a figment) appears. You are
    then free to go elsewhere while your double moves away. The double appears
    within range but thereafter moves as you direct it. You can make the figment
    appear superimposed perfectly over your own body so that observers don’t
    notice an image appearing and you turning invisible. The double moves at
    your speed and can talk and gesture as if it were real, but it cannot
    attack or cast spells, though it can pretend to do so.

    Actions you can give it as a henchmen is "Follow" "Do nothing (stand ground)"
    "Attack (Pretend to attack)".

    The illusory double lasts as long as you concentrate upon it, plus 3
    additional rounds. After you cease concentration, the illusory double
    continues to carry out the same activity until the duration expires. The
    improved invisibility lasts for 1 round per level, regardless of concentration.
//:://////////////////////////////////////////////
//:: Spell Effects Applied / Notes
//:://////////////////////////////////////////////
    As the spell says. This can be done in part (but never perfectly, it is
    a real-time computer game).

    The illusion is a CopyObject() of the person. It has full consealment against
    attacks and is plotted.

    A temp effect is added so the illusion can be dispelled.

    An additional, a heartbeat is added to the copy so it can do actions (fake ones).
