The Duo-Dimension, 10' radius spell causes a group of creatures to have only two dimensions, height and width but no depth. These creatures are thus invisible when turned sideways. This invisibility can only be detected by means of a True Seeing spell or similar methods. In addition, the duo-dimensional creatures can pass thru the thinnest of spaces as long as these have the proper height - going thru the space between a door and its frame is a simple matter. The subjects can perform all actions normally. They can turn and become invisible, move in this state, and appear again next round to attack, disappearing on the following round.

Note that when turned, the subjects cannot be affected by any form of attack, but when visible, they are subject to double the amount of damage normal for the attack form (a dagger thrust does 2d4 hp damage, for example). Furthermore, the subjects have a portion of their existence in the Astral Plane while the spell is in effect, and are subject to possible notice by Astral creatures. If noticed, it is 25% probable that the subjects of this spell are pulled entirely into the Astral by any attack from an Astral creature. Such an attack inflicts normal damage.

The spell confers duo-dimensionality upon the touched subject, as well as all those creatures within a 10' radius of the subject. Any affected creatures moving out of the radius return to normal, altho no creatures entering the area after the spell is cast are affected. The spell recipient remains in duo-dimensional form for the entire duration of the spell.

The material components of this spell are a small klein bottle and a strip of parchment. As the spell is uttered, the parchment is given a half-twist and joined at the ends. The bottle is then passed thru the parchment loop, both disappearing right as it passes thru.
