    Divination
    Level: Luck 8, Sor/Wiz 8
    Components: V, S
    Casting Time: 1 standard action
    Range: Personal
    Target: You
    Duration: 1 hour/level or until discharged

    This spell grants you a powerful sixth sense in relation to yourself. In NwN,
    you may choose to add a 25 bonus to the next hostile spell save against an
    enemy (Only one save), or add it to one saving throw you yourself make against
    another caster. Alternativly, you can apply it for a 6 second bonus to your AC
    (Applied in Natural Armor, even when flatfooted). Once used, the spell ends.

    You can’t have more than one moment of prescience active on you at the same
    time.

    This applies a visual, well, doesn't actually apply a good one until it
    comes into effect.

    Applies a cessate one here - which notably doesn't stack.

    It is checked for in the spell save DC files - PHS_INC_SAVES, which does
    all the save work.

    It can of course apply 25AC (Which is kinda a waste), but the choice is thiers
    and this uses the menu - no sub dial (for easy GetHasSpellEffect() things).
