    Evocation
    Level: Clr 3
    Components: V, S
    Casting Time: 1 standard action
    Range: Personal
    Target: You
    Duration: 1 min./level (D)

    You surround yourself with a sphere of power with a radius of 1.67M per
    2 caster levels (Maximum 16.67M at level 20) that negates all forms of
    invisibility. Anything invisible has thier invisibility removed while in
    the area. Natural hiding is not affected.

//:://////////////////////////////////////////////
    I altered it so people wouldn't be put under a false impression.

    Anyones invsibility is removed!

    The AOE changes per 2 caster levels - not per 1, this makes it more
    manageable for NwN, and is still a huge radius as the spell progresses
    in levels!
